Back to the motor

Dear Valued Customer Small, precise, powerful – and at the core the ironless maxon winding. You can already see it on the front page. Our new motors are a key aspect of the maxon catalog 2012/13. We have made them even more powerful and robust to solve the most demanding drive task problems, together with you. Hotter than ever With the EC 22 HD (Heavy Duty), maxon motor is launching a standard motor for extremely harsh working conditions. The brushless DC motor, which has been designed for the extremely high requirements in the field of deep drilling, can also withstand harsh environmental conditions: The EC 22 HD has been designed for temperatures of more than 200°C and atmospheric pressures of up to 1700 bar. It is also resistant to large

vibration and shocks. The motor opens up new possibilities for a wide range of applications. It is predestined, for example, for use in the astronautics industry, in power stations, in automotive and aircraft construction or in underground applications. Stronger than ever The successful series of brushless maxon EC 45 flat motors is continually expanding. The family is joined by a completely newly designed 70 watt model. The new EC 45 flat 70 W is characterized by a very flat speed/torque gradient and combines old with new: Flange pattern, mounting and plugs are identical to the existing 50 W model. Nonetheless, the 70 watt model delivers 38 percent more torque. As easily combinable as ever The new EC 45 flat 70 W is available

with Hall sensors in four winding types (24, 30, 36, 48 V) and can be combined with over 50 different planetary and spur gearheads from the GP 42 C and GS 45 A series. A number of servo amplifiers (DEC, DECS, DECV and DES) and position controllers (EPOS2 and EPOS2 P) are available for control. For the EC 22 HD there is also the robust new planetary gearhead GP 22 HD with the same diameter. And with the new ESCON 36/2 and ESCON 50/5 servo amplifiers you will always have your DC drives under control. Best regards,

Eugen Elmiger CEO

maxon DC motor maxon DC motors are highquality motors fitted with powerful permanent magnets. The “heart” of the motor is the worldwide patented ironless rotor. This means using cutting-edge technology to produce compact, powerful and low inertia drives. These DC motors have very fast acceleration thanks to their low mass moment of inertia. The modular construction of the A-max and RE-max programmes offer countless options and top performance at competitive prices.

maxon EC motor Our electronically commutated DC motors are characterized in particular par ticular by favourable torque behaviour, high performance, an extremely wide speed range and unprecedented service ser vice life. Their outstanding control features help create precision positioning drives. Similar to the ideology of the A-max programme, a modular motor range is available with the EC-max programme. p rogramme. The EC-4pole range provides top performance per volume unit, pushing the boundaries of technology.

maxon flat motor The flat design of the brushless DC flat motors makes them the ideal drive for many applications. Designed as internal or external rotor motors, they are often the ideal solution when space is limited. The well thought-out and simple design means that production is largely automated, helping keep down the price.

The maxon winding

Service life

The “heart” of the maxon motor is the world-wide patented ironless winding, System maxon ® : This motor principle has very specific advanta advantages. ges. There is no magnetic detent and minimal electromagnetic interference. The efficiency of up to 90% exceeds that of other motor systems.

A general statement about service life li fe cannot be made due to many influencing factors. Service life can vary between more than 20 000 hours under favorable conditions, and less than 100 hours under extreme conditions (in rare cases). Roughly 1000 to 3000 hours are attained with average requirements.

There are numerous winding variants for each motor type (see motor data sheets). They are differentiated by the wire diameter and number of turns. This results in various motor terminal resistances. The wire sizes used are between 32 µm and 0.45 mm, resulting in the different terminal resistances of the motors. This influences the motor parameters that describe the transformation of electrical and mechanical energy (torque and speed constants). It allows you to select the motor that is best suited to your application. The maximum permissible winding temperature in high-temperature applications is 125°C (155°C in special cases), otherwise 85°C. Effects of wire gauge and number of windings are:

Turning speed The optimal operating speeds are between 4000 rpm and 9000 rpm dependin depending g on the motor size. Speeds of more than 20 000 rpm have been attained with some special versions. A physical property of a DC motor is that, at a constant voltage, the speed is reduced with increasing loads. A good adaptation to the desired conditions is possible thanks to a variety of winding variants. At lower speeds, a gear combination is often more favorable than a slowly turning motor.

Low terminal resistance – Low resistanc resistance e winding – Thick wire, few few turns – High starting starting currents – High specific speed speed (rpm per volt) volt) High terminal resistance – High resistanc resistance e winding – Thin wire, wire, many turns – Low starting starting currents – Low specific speed speed (rpm per volt)

The following have an influence: 1. The electric load: higher current loads result in greater electric wear. Therefore, it may be advisable to select a somewhat stronger motor for certain applications. We would be happy to advise you. 2. Speed: the higher the speed, the greater the mechanical wear. 3. Type Type of operation: extreme start/stop, left/right operation leads to a reduction in service life. 4. Environmental influences: temperature, influences: temperature, humidity, vibration, type of installation, etc. 5. In the case of precious metal brushes, 5. In the CLL concept increases concept increases service life at higher loads and the benefits of precious metal brushes are retained. 6.  Combination 6. Combinations s of graphite brushes and brushes and ball bearings lead to a long service life, even under extreme conditions.

Mechanical commutation Graphite brushes In combination with copper commutators for the most rigorous applications. More than 10 million cycles were attained in different applications.

Graphite brushes are typically used: – In larger larger motors – With high current current loads – In start/stop operation – In reverse reverse operation – While controlling controlling at pulsed power stage (PWM) The special properties of graphite brushes can brushes can cause so-called spikes. They are visible in the commutation pattern. Despite the high-frequency interference caused by the spikes, these motors have become popular in applications with electronic controls. Please note, that the contact resistance of the graphite brushes changes dependent on load.

Precious metal brushes and commutator Our precious metal combinations ensure a highly constant and low contact resistance, even after a prolonged standstill time. The motors work with very low starting voltages and electromagnetic interferences. Precious metal brushes are typically used: – In small motors – In continuous operation – With small current current loads loads – With battery battery operation – In DC tachometers The commutation pattern is uniform and free of spikes, as opposed to that of other motors. The combination of precious metal brushes and maxon rotor system results in minimum of high-frequency interference, which otherwise leads to major problems in electronical circuits. The motors need practically no interference suppression.

Commutation pattern with graphite brushes

For further explanations, please see page 49 or “The selection of high-precision microdrives” by Dr. Urs Kafader.

Commutation pattern The commutation pattern shows the current pattern of a maxon DC motor over one motor revolution. Please place a low-ohm series resistor in series with the motor (approx. 50 times smaller than the motor resistance). Observe the voltage drop over the resistor on the oscilloscope.

Commutation pattern with precious metal brushes





CLL concept With precious metal commutation, the wear on commutators commutator s and brushes is caused mainly by sparks. The CLL concept suppresses spark generation to a large extent, thus greatly extending service life. When driven with a pulsed power stage (PWM) higher no-load currents occur and an unwanted motor heating can result.

Service life The gears usually achieve 1000 to 3000 operating hours in continuous operation at the maximum permissible load and recommended input speed. Service life is significantly extended if these limitsdrops are not pushed. If the speed below this threshold, the gearhead may be loaded with higher torques without compromising the life span. On the other hand, higher speeds and thus higher reduction ratios can be chosen if the torque limits are not fully exploited. Factors affecting life span include: – Exceeding maximum torque can lead to excessive wear. – Local temperature peaks in the area of tooth contact can destroy the lubricant. – Massively exceeding the gear input speed reduces the service life. – Radial and axial loads loads on the bearing.

Temperature/lubrication maxon gears are lubricated for life. The lubricants used are especially effective in the recommended temperature range. At higher or lower operating temperatures we offer recommendations for special lubricants.

Selection of gears

Spur gearhead

For the selection of the gearhead, the maximum transmittable power – the product of speed and torque – is decisive. It should be noted that the transmittable power depends on the number of gear stages. The load torque should be below the nominal torque (max. continuous torque) of the gearhead M N,G  N,G . 

The gear consists of one or more stages. One stage represents the pairing of two cogwheels. The first cogwheel (pinion) is mounted directly on the motor shaft. The bearing of the output shaft is usually made of sintered material. – Favorably priced – For low torques – Output torque up to 2 Nm – Reduction ratios of 6:1 to 5752:1 – External - Ø12 - 45 45 mm – Low noise level – High efficiency

For short-term loading, the short-term torque of the gearhead must also be considered. Where possible, the input speed of the gear i max  max   should not be exceeded.

Planetary gearhead Planetary gears are particularly suitable for the transfer of high torques. Large gearheads are normally fitted with ball bearings at gearhead output. – For transferring high torques up to 180 Nm – Reduction ratios of 4:1 to 6285:1 – External diameter diameter 6–81 mm – High performance performance in a small space – High reduction ratio ratio in a small space – Concentri Concentric c gear input and output Plastic versions Favorably priced and yet compact drives can be realized with plastic gears. The mechanical load is slightly smaller than that of metal designs, however, it is significantly higher than that of spur gears.

Ceramic versions By using ceramic components in gearheads, the wear characteristics of critical components can be significantly improved. The result when compared to purely metal gearheads is: – Longer service life – Higher continuous torques – Higher intermittent intermittent torques – Higher input speeds High power gearhead Especially high output torques in the output stage of planetary gearheads can be achieved through the following measures – Use of ceramic components – 4 instead of 3 planet gears in the output stage – Additional motor-side motor-side support of the output output stage – Reinforcement of the output bearings Heavy duty gearhead The HD (heavy duty) gearheads are characterized by their robust construction. The use of stainless steel and optimized welding joints enable use under the most extreme conditions.

Koaxdrive Noise reduction Noise is primarily generate generated d in the input stage of the gearhead. The following measures can help to reduce noise: – Smaller input speeds and thus smaller relative velocity of the tooth flanks – Input stage with plastic gears – Use of a Koaxdrive gearhead The quiet “Koaxdrive” combines worm and planetary gearing. In the first stage, a separately mounted worm drives the three offset planetary wheels which then mesh in the specially toothed internal geared wheel. All further stages are designed as a normal planetary gear: – low noise – high reduction ratio ratio in the first stage – other properties properties as planetary gears gears

Reduced backlash gearhead The reduction in backlash is achieved through a patented preloading of the planet gears in the output stage. Despite the wear that occurs during operation, the gearhead backlash remains constantly low, unlike for gearheads in which the backlash reduction is achieved by low-tolerance manufacturing manufa cturing and material pairing. Sterilizable gearhead Sterilizable gearheads are characterized by the use of stainless steel and special lubricants. The bearing of the output shaft and the connection to the motor are designed so that fluid leaking into the gearhead is inhibited.

Digital Incremental Encoder

Magnetic principles

Encoder signals For further processing in the controller, the encoders deliver square-wave signals whose pulses can be counted for exact positioning or speed measurement. Channels A and B pick up phase shifted signals, which are compared with one another to determine the rotation direction. All maxon positioning systems evaluate the rising and falling signal edges. With regard to encoder number number of pulses, this results in i n a four times higher positioning precision. This This is what is referred to as quadcounts. A “home” pulse (index channel I) can be used as a reference point for precise determination of rotation angle. The line driver produces complementary signals – – A, B, I which help to eliminate interference on long signal lines. In addition, this electronic driver installed in the encoder improves improves signal quality by steeper signal edges.

On the magnetic Encoder a small multipole permanent magnet sits on the motor shaft. The changes in the magnetic flow are recorded by sensors and supplied to the electronics as processed channel A and B. Magnetic encoders require a minimum of space.

Tips on encoder selection

Resolver

Principal features of the maxon incremental encoder are: – The number of pulses per revolution (increments) – The T he accuracy – Use of an index channel – The use of a line driver – The maximum supported supported speed – The suitability for special ambient ambient conditions (dust, oil, magnetic fields, ionizing radiation) Encoders and maxon controllers – As a standard the maxon maxon controllers are prepreset for encoders with 500 pulses per revolution. – The input frequency frequency of the controller electronics can limit the maximum possible counts per turn of the encoder. – The higher the number of pulses and the higher the accuracy the better a smooth, jerkfree operation can be achieved even at low speeds. – maxon controllers can be set for low or high speed operation and for encoders with a low or high number of pulses.

Schematic design of the inductive MILE encoder

The following applies especially to positioning systems: – The higher the number number of pulses, the more precise the position that can be reached. At 500 pulses (2000 quadcounts) an angle resolution of 0.18° is achieve achieved, d, which is usually much better than the precision of the mechanical drive components (e.g. due to gear play or elasticity of drive belts). – Only encoders with an integrated integrated line driver (RS422) should be used in positioning controls. This prevents electromagnetic interference signals from causing signal loss and accumulated positioning errors. – Positioning applications often require the index channel of the encoder for precise reference point detection.

Characteristics – Robust, for industri industrial al use – Long service service life – No mechanical wear – Output signal can be transmitted over long distances without problems – No sensitive electronics – Special signal evaluation evaluation required – Only one sensor for position and speed information – EC motors with resolver resolver are supplied without Hall sensors

Speed control The function of the speed servo amplifier is to keep the prescribed motor speed constant and independent of load changes. To achieve this, the set value (desired speed) is continuou continuously sly compared with the actual value (actual speed) in the control electronics of the servo amplifier. The controller difference determined in this way is used by the controller to regulate the power stage of the servo amplifier in such a manner

The motor is equipped with a digital encoder that provides a certain number of pulses per revolution. The turning direction is detected with the square pulses of channels A and B offset by 90 electric degrees. – Digital encoders are often found found in positioning controls, in order to derive and measure the travel or angle. – Digital encoders are are not subject to mechamechanical wear.

The motor is provided with a voltage that is proportional to the applied speed set value. The speed would drop with increasing i ncreasing motor load. The The compensation circuitry increases the output voltage with increasing motor current. The compensation must be adjusted to the terminal resistance of the motor which depends on temperature and load.

is subject to limits in the percent range. – Favorably priced and space-saving – No tacho-generator or encoder required – Less precise control when there is a load change – Only analog speed speed control possible possible – Ideal for for low-cost applications without high demands on speed accuracy

Position control The positioning control ensures a match between the currently measured position with a target position, by providing the motor with the corresponding correction values, as with a speed controller. The position data are usually obtained from a digital encoder.

The attainable speed precision of such a system

Current control The current control provides the motor with a current proportional to the set value. Accordingly, the motor torque changes proportionally to the set value. The current controller also improves the dynamics of a superior positioning or speed control circuit.

The torque constant is also called specific torque. The reciprocal value is called specific current or current constant.

The main point of this proportionality is that torque and current are equivalent for the maxon motor. The current axis in i n the motor diagrams is therefor therefore e shown as parallel to the torque axis as well.

The speed-torque gradient is one of the most informative pieces of data and allows direct comparison between different motors. The smaller the speed-torque gradient, the less sensitive the speed reacts to torque (load) changes and the stronger the motor. With the maxon motor, the speedtorque gradient within the winding series of a motor type (i.e. on one catalog page) remains practically constant.

Speed n

Current gradient The equivalence of current to torque is shown by an axis parallel to the torque: more current flowing through the motor produces more torque. The current scale is determined by the two points no-load current I 0 0 and starting   current I A (lines 3 and 8 of motor data). The no-load current is equivalen equivalentt to the friction torque M R  R , that describes the internal friction in the bearings and commutation system.  M   R = k   M  · I  0

In the maxon EC motor, there are strong, speed dependent iron losses in the stator iron stack instead of friction losses in the commutation system. The motors develop the highest torque when starting. It is many times greater than the normal operating torque, so the current uptake is the greatest as well.

Motor diagrams, operating ranges

  r

The catalogue contains a diagram of every maxon DC and EC motor type that shows the operating ranges of the different winding types using a typical motor.

operating range    t   o Permanent The two criteria “maximum continuou continuous s torque” and “maximum permis- sible   m speed” limit the continuous operating range. Operating points within this   n range are not critical thermally and do not generally cause increased wear   o of the commutation system.   x   a Short-term operating range   m The motor may only be loaded with the maximum continuous current for thermal reasons. However, temporary higher currents (torques) are allowed. As long as the winding temperature is below the critical value, the winding will not be damaged. Phases Phases with increased i ncreased currents are time limited. A measure of how long the temporary overload can last is provided by the thermal time constant of the winding (line 19 of the motor data). The magnitude of the times with overload ranges from several seconds for the smallest motors (6 mm to 13 mm diameter) up to roughly one minute for the largest (60 mm to 90 mm diameter). The calculation of the exact overload time is heavily dependent on the motor current and the rotor’s starting temperature. Maximum continuous current, maximum continuous torque The Jule power losses heat up the winding. The heat produced must be able to dissipate and the maximum rotor temperature (line 22 of the motor data) should not be exceeded. This results in a maximum continuous current, at which the maximum winding temperature is attained under standard conditions (25°C ambient temperature, no heat dissipation via the flange, free air circulation). Higher motor currents cause excessive winding temperatures. The nominal current is selected so that it corresponds to this maximum permissible constant current. It depends heavily on the winding. These thin wire windings have lower nominal current levels than thick ones. With very low resistive windings, the brush system‘s capacity can further limit the permissible constant current. With graphite brush motors, friction losses increase sharply at higher speeds. With EC motors, eddy current losses increase in the return as speed increases and produce additional heat. The maximum permissible continuous current decreases at faster speeds accordingly. The nominal torque allocated to the nominal current is almost constant

The maximum speed for DC motors ispermissible primarily limited by the commutation system. The commutator and brushes wear more rapidly at very high speeds. The reasons are: – Increased mechanical mechanica l wear because of the large traveled path of the commutator – Increased electro-erosion electro-erosion because of brush vibration vibration and spark formation.

A further reason for limiting the speed is the rotor’s residual mechanical mechanical imbalance which shortens the ser vice life of the bearings. Higher Higher speeds than the limit speed n max  max  (line 23) are possible, however, they are “paid for” by a reduced service life expectancy. The maximum permissible speed for the EC motor is calculated based on service life considerations of the ball bearings (at least 20 000 hours) at the maximum residual imbalance and bearing load. Maximum winding temperature The motor current causes the winding to heat up due to the winding’s resistance. To prevent the motor from overheating, this heat must dissipate to the environment via the stator. The coreless winding is the thermally critical point. The maximum rotor temperature must not be exceeded, even temporarily. With graphite brush motors and EC motors which tend to have higher current loads, the maximum rotor temperatu temperature re is 125°C (in individual cases up to 155°C). Motors with precious metal commutators only allow lower current loads, so that the rotor temperatures must not exceed 85°C. Favourable mounting conditions, such as good air circulation or cooling plates, can significantly lower temperatures.

maxon flat motor Multipole EC motors, such as maxon flat motors, require a greater number of commutation steps for a motor revolution (6 x number of pole pairs).

As a result, motor behaviour deviates from the ideal linear speed-torq speed-torque ue gradient. The apparent speed-torque gradient depends on voltage and speed: The gradient is steeper at higher speeds. Mostly, flat motors are operated in the continuous operation range where the achievable speed-torque gradient at nominal voltage can be approximated by a straight line between no-load speed and nominal working point.

Acceleration In accordance with the electrical boundary conditions (power supply, control, battery), a distinction is principally made between two different different starting processes: – Start at constant voltage (without (without current limitation) – Start at constant current current (with current limitation) Start under constant current A current limit always means that the motor can only deliver a limited torque. In the speed-torque diagram, the speed increases on a vertical line with a constant torque. Acceleration is also constant, thus simplifying the calculation. Start at constant current is usually found in applications with servo amplifiers, where acceleration torques are limited by the amplifier‘s peak current.

Thermal behavior Influence of temperature An increased motor temperature affects winding resistance and magnetic characteristic values.

The modified thermal resistance R th2  th2  that occurs in a particular application must be determined using original installation and ambient conditions. Thermal resistance R th2  th2  on motors with metal flanges decreases by up to 80% if the motor is coupled to a good heat-conducting (e.g. metallic) retainer. The heating runs at different rates for the winding and stator due to the different masses. After switching on the current, the winding heats up first (with time constants from several seconds to half a minute). The stator reacts much slower, with time constants ranging from 1 to 30 minutes depending on motor size. A thermal balance is gradually established.

Motor selection The drive requirements must be defined before proceeding to motor selection. – How fast and at which torques does the load move? – How long do the individual load phases last? – What accelerations take place? – How great great are the mass inertias? Often drive is indirect, means that there is a mechanical mationthe of the motor outputthis power using belts, gears, screws and transforthe like. The drive parameters, therefore, are to be calculated to the motor shaft. Additional steps for gear selection are listed below. Furthermore, the power supply requirements need to be checked. – Which maximum voltage voltage is available at the motor terminals? – Which limitations apply apply with regard to current? current? The current and voltage of motors supplied with batteries or solar cells are very limited. In the case of control of the unit via a ser vo amplifier, the amplifier’s maximum current is often an important limit. Selection of motor types The possible motor types are selected using the required torque. On the one hand, the peak torque, M max  max , is to be taken into consideration and on the other, the effective torque M RMS  RMS . Continuous operation is characterized by a single operating or load point (M L, n L ). The motor types in i n question must have a nominal torque (= max. continuous torque) M N  is greater N that   than operating torque M B  B.   M  N  > M   B

In work cycles, such as start/stop operation, the motor‘s nominal torque must be greater than the effective load torque (quadratically averaged). This prevents the motor from overheating.  M  N  > M   RMS 

Advices for evaluating the requirements: Often the load points (especially the torque) are not known or are difficult to determine. In such cases you can operate your device with a measuring motor roughly estimated according to size and power. Vary the voltage until the desired operating points and motion sequences have been achieved. Measure the voltage and current flow. Using these specifications and the order number of the measuring motor, our engineers can often specify the suitable motor for your application. Additional optimization criteria are, for example: – Mass to be accelerated (type, mass inertia) – Type of operation (continuous, intermittent, reversing) – Ambient conditions (temperature, humidity, medium) – Power supply, supply, battery

When selecting the motor type, other constraints also play a major role: – What maximum length should the drive unit have, have, including gear and encoder? – What diameter? – What service life is expected from the motor and which commutation system should be used? – Precious metal commutation for continuous operation at low currents (rule of thumb for longest ser vice life: up to approx. 50% of I N  N )    – Graphite commutation for high continuous currents (rule of thumb: 50% to approx. 75% of I N   and frequent current peaks N )     and (start/stop operation, reversing operation). – Electronic commutation commutati on for highest speeds and longest servic service e life. – How great are the forces forces on the shaft, do ball bearings have to be used or are less expensive sintered bearings sufficient?

The stall torque of the selected motor should usually exceed the emerging load peak torque.  M  H  > M max max

Selection of the winding: electric requirement In selecting the winding, it must be ensured that the voltage applied directly to the motor is sufficient for attaining the required speed in all operating points. Unregulated operation In applications with only one operating point, this is often achieved with a fixed voltage U. A winding is sought with a speed-torque line that passes through the operating point at the specified voltage. The calculation uses the fact that all motors of a type feature practically the same speed-torque gradient. A target no-load speed n 0,theor  0,theor  is calculated from operating point (n L, M L ). 0 , theor   L +

Those windings whose kn is as close to k n, n, theor  as possible, will approximate the operating point the best at the specified voltage. A somewhat larger speed constant results in a somewhat higher speed, a smaller speed constant results in a lower one. The variation of the voltage adjusts the speed to the required value, a principle that servo amplifiers also use.

Finally, the average current load   m and peak current are calculated ensuring that the servo amplifier used can deliver these currents.

Gear selection A gear is required with a maximum continuous torque of at least 0.28 Nm and an intermittent torque of at least 0.47 Nm. This requirement is fulfilled, for example, by a planetary gear with 22 mm diameter (metal version GB 22 A). The recommended input speed of 6000 rpm allows a maximum reduction of: imax =

The possible motors, which match the selected gears in accordance with the maxon modular system, are summarized in the table opposite. The table contains only DC motors with graphite commutation, which are better suited for start-stop operation, as well as brushless EC motors. Selection falls on an A-max 22, 6 W, which demonstrates a sufficiently high continuous torque. The motor should have a torque reserve so that it can even function with a somewhat unfavorable gear efficiency. The additional torque requirement during acceleration can easily be delivered by the motor. The temporary peak torque is not even twice as high as the continuous torque of the motor. Selection of the winding The motor type A-max 22, 6 W has an average speed-torque gradient of some 450 rpm/mNm. However, it should be noted that the two lowest resistance windings have a somewhat steeper gradient. The desired no-load speed is calculated as follows: 0 , theor   mot  +

      max = 5040 + 450   9.6  9.6 = 9360 rpm   

The extreme working point should of course be used in the calculation (max. speed and max. torque), since the speed-torque line of the winding must run above all working points in the speed / torque diagram. This target no-load speed must be achieved with the maximum voltage U  =  = 24 V supplied by the control (ESCON 36/2), which defines the minimum target speed constant k n, n, theor  of the motor.

k n, theor  =

n0 , theor  U 

=

9360 rpm = 390 V  24

According to the calculations, the selection of the motor is 110163, which with its speed constant of 558 rpm/V has a speed control reserve of over 20%. This means that unfavorable tolerances are not a problem. The higher speed constant of the winding compared to the calculated value means that the motor runs faster at 24 V than required, which can be compensated with the controller. This motor also has a second shaft end for mounting an encoder. The torque constant of this winding is 17.1 mNm/A. Therefore the maxi-

In order to our high quality standard, weguarantee check materials, parts and subassemblies through the manufacturing process and the complete motor. The obtained measurements are recorded and can be made available to customers if required. Random sampling plans are according to ISO 2859, MIL STD 105E and DIN/ISO 3951 (inspection by attributes, sequential sampling, variables inspection) as well as internal manufacturing controls. This specification always applies unless a different one has been agreed between the customer and maxon.

2. Data 2.1 Electrical data  data  apply at 22° to 25°C. Data control within one minute running time.   Measurement voltage +/voltage +/- 0.5 % for voltages  3V and ± 0.015 V for voltages  3V   No-load speed  speed  ± 10%   No-load current  current   maximum specified value   Sense of rotation cw rotation cw = clockwise   Motor position  position  horizontal   Notes: Measurement voltage may vary from the nominal voltage listed in the catalog. The no load current specified in the catalog is a typical value and not the maximum one. By connecting the red wires or if voltage is applied to the ‘+’ Terminal, shaft rotation is cw (clockwise) as seen from the mounting end. For ccw running, the specified tolerance data may only be marginally exceeded.   Terminal resistance:  resistance:  Winding resistance is verified in the manufacturing process through spot checks on a representative basis. Terminal resistance is determined at product certification. It should be noted that terminal resistance depends on the rotor’s rotational position. As transfer resistance depends on current density in graphite brushes, measuring resistance with an ohmmeter if the current is low does not give reasonable results. Too low a reading is produced with precious metal brush motors if the brushes bridge two commutator segments, thereby short-circuiting one coil segment.   Inductance is determined at product certification. Test frequency is 1 kHz. The motor’s terminal inductance depends on frequency.   Commutation: An oscilloscope is used to check the neutral setting and test for electrical faults, such as interrupted winding or short-circuit between turns. Commutation displays for precious metal brushes and graphite brushes are not directly comparable. Precious metal brushes display a clear commutation picture which remains interference free up to the motor‘s recommended maximum speed, but with graphite brushes, this is only expected up to around one third of that. In addition, it should be noted that the con-

2.2 Mechanical data  data  per outline drawing: Standardmeasuring instruments (for electrical length measuring DIN 32876, micrometer per DIN 863, dial indicator DIN 878, calliper per DIN 862, bore calliper DIN 2245, thread calliper per DIN 2280 and others) are used. 2.3 Rotor imbalance: Rotors are balanced according to standard data or customer requirements during manuf manufacturing. acturing. 2.4 Noise: Tests are carried out for anomalies within a lot, on a subjective basis. Depending on speed, the motions in the motor cause noise and vibration of varying degrees, frequency and intensity. The noise level experienced with a single sample unit should not be interpreted as indicative of the noise or vibration level to be expected of future deliveries. 2.5 Service life: Durability life: Durability tests are carried out under uniform internal criteria as part of product certification. A motor‘s service life essentially depends on the operating and ambient conditions. Consequently, the many possible variations do not allow us to make a general statement on service life. 2.6 Environmental influences   Protection against corrosion: Our products are tested during product cer tification on the basis of DIN EN 60068-2-30. Coating of components: Surface components: Surface treatment and coating procedures used by maxon are selected on the basis of their merits to resist corrosion. These treatments are evaluated at product certification according to their applicable standard.  3. Parameters that differ from or are additional to the data sheet can be specified and will be then a central part of our systematic testing as the customer‘s specification. Test/inspection certificates are issued by prior agreemen agreement. t. January 2010 edition / subject to change

Explanation of the pages 50–134 Dimensional drawings On the enclosed DVD dimensional drawings (DXF-files) are available and are suitable for import to any CAD system. Presentation of the views according to the projection method E (ISO). All dimensions in [mm]. Mounting threads in plastic Screwed connections on motors with plastic flanges require special attention. MA  Max. tightening torque  torque  [Ncm] A torque screw driver may be adjusted to this value. L 

Active depth of screw connection  connection  [mm] The relation of the depth of the screw connection to the thread diameter must be at least 2:1. The depth of the screw connection must be less than the usable length of the thread! Motor Data The values stated are based on a motor temperatem perature of 25°C (so-called cold data). Line 1  1  Nominal voltage  voltage  UN [Volt] is the DC voltage on the motor connections on which all nominal data are based (lines 2 - 9). Lower and higher voltages are permissible, provided set limits are not exceeded. Line 2  2 

No load speed  speed  n0 [rpm] ±10%

This is the speed at whichload. the motor turns at nominal voltage and without It is approximately proportional to the applied voltage. Line 3  3  No load current  current  I0 [mA] ±50% This is the typical current that the unloaded motor draws when operating at nominal voltage. It depends on brush friction and friction in the bearings, and also increases with rising speed. No-load friction depends heavily on temperature, particularly with precious metal commutation. In extended operation, no-load friction decreases and increases at lower temperatures. Line 4  4  Nominal speed  speed  nN [rpm] is the speed set for operation at nominal voltage and nominal torque at a motor temperature of 25°C. Line 5  5  Nominal torque  torque  MN [mNm] is the torque generated for operation at nominal voltage and nominal current at a motor temperature of 25°C. It is at the limit of the motor's continuous operation range. Higher torques heat up the winding too much. Line 6  6  Nominal current  current  IN [A] is the current that, at 25°C ambient temperature, heats the winding up to the maximum permissible temperature (= max. permissible continuous current). IN decreases as speed increases due to additional friction losses.

Line 7  7  Stall torque  torque  MH [mNm] is the torque produced by the motor when at standstill. Rising motor temperatures reduce stall torque. Line 8  8  Starting current  current  IA [A] is the quotient from nominal voltage and the motor's terminal resistance. Starting current is equivalent to stall torque. With larger motors, I A  cannot often be reached due to the amplifier's current limits. Line 9 optimal Maximum efficiency efficiency    max [%] is the9  relationship between input and output power at nominal voltage. It also doesn't always denote the optimal operating point. Line 10  10  Terminal resistance  resistance  R [] is the resistance at the terminals at 25°C and determines the starting current at a given voltage. For graphite brushes, it should be noted that resistance is load-dependent and the value only applies to large currents. Line 11  11  Terminal inductance  inductance  L [mH] is the winding inductance when stationary and measured at 1 kHz, sinusoidal. Line 12  12  Torque constant kM [mNm/A] This may also be referred to as "specific torque" and represents the quotient from generated torque and applicable current. Line 13  13  Speed constant  constant  kn [rpm/V] shows the ideal no load speed per 1 volt of applied voltage. Friction losses not taken into account. Line 14  14  Speed / torque gradient  gradient  n / M [rpm/mNm] The speed / torque gradient is an indicator of the motor's performance. The smaller the value, the more powerful the motor and consequently the less motor speed varies with load l oad variations. It is based on the quotient of ideal no-load speed and ideal stall torque. Line 15  15  Mechanical time constant  constant  m [ms] is the time required for the rotor to accelerate from standstill to 63% of its no-load speed. Line 16  16  Rotor inertia  inertia  JR [gcm2] is the mass moment of inertia i nertia of the rotor, based on the axis of rotation. Line 17  17  Thermal resistance housing-ambient   Rth2 [K/W] housing-ambient and Line 18  18  Thermal resistance winding-housing   Rth1 [K/W] winding-housing Characteristic values of thermal contact resistance without additional heat sinking. Lines 17 and 18 combined define the maximum heating at a given power loss (load). Thermal resistance Rth2  on motors with metal flanges can decrease by up to 80% if the motor is coupled directly to a good heat-conducting (e.g. metallic) mounting rather than a plastic panel.

Line 19  19  Thermal time constant winding  winding  w [s] and Line 20  20  Thermal time constant motor m [s] These are the typical reaction times for a temperature change of winding and motor. It can be seen that the motor reacts much more sluggishly in thermal terms than the winding.The values are calculated from the product of thermal capacity and given heat resistances. Line 21  21  Ambient temperature  temperature  [°C] Operating temperature range. This derives from the heat reliability of the materials used and viscosity of bearing lubrication. Line 22  22  Max. winding temperature  temperature  [°C] Maximum permissible winding temperature. Line 23  23  Maximum permissible speed  speed  nmax [rpm] is the maximum recommended speed based on thermal and mechanical perspectives. A reduced service life can be expected at higher speeds. Line 24  24  Axial play  play  [mm] For non-preloadedmotors, this represents the tolerance limits of the factory-set bearing play. The latter is included in shaft length tolerances. Pre-loading cancels out axial play up to the given axial loading. Line 25  25  Radial play  play  [mm] Radial play derives from the bearings' radial air. A preload) cancels out radial play upspring to the(bearing given axial loading. Line 26 / 27  27  Max. axial loading  loading  [N] dynamically:   axial loading permissible in opdynamically: eration.
