2. PRODUCT DESCRIPTION

Versions: Two versions are available: a) Vertical and horizontal motor position for machine in machine room (TWR) b) Horizontal motor position for machine in shaft (MRL) Compared to version with machine in machine room (TWR) the model of the machine for use in shaft (MRL) is equipped with two-surface disc brakes in tandem arrangement with higher braking torque but without mounted-on brake release levers and handwinding wheel. The following versions are available: Drive rating Gear ratio Traction sheave version Traction sheave in left-hand and right-hand design with horizontal motor position (seen from motor to gear) Encoder version An optionally mounted emergency braking system NBS prevents overspeed in upwards direction. It has an additional disk brake acting on the traction sheave shaft. Note: It is not possible to retrofit an existing machine with an NBS emergency braking system !

2.2

Functional description Machine TW45B is designed for driving lift cars with rated load 450 kg and speed 1,0 ≤ v ≤ 1,25 m/s. The gear (shaft) consists of a single-stage worm gear in monoblock housing with separated AS/BS bearing brackets. A flexible coupling transmits the power from motor to gear. A dual-circuit disc brake is installed between motor and gear. An overhung traction sheave is used. Tooth system operating in synthetic oil. Attention: the gear can be considered self-locking for ratio > 25.5. Observe that this does not apply to lower ratio. Different designs of drives are used dependent on the position of the flanged three-phase motor. The drive transmits power to the worm shaft and from there to the worm wheel, traction sheave shaft and traction sheave. TW45B has flange-mounted motors (∅250 mm) in B5 / V1 design. Integrated posistors protect the motor against thermal overload. The thermal motor monitoring is connected in the motor terminal box. Details see chapter 2.4.

2. PRODUCT DESCRIPTION

Drive type: TW45B is available with frequency-controlled three-phase motor only. An encoder for speed monitoring is available optionally. It is mounted on the motor shaft. Technical data and manufacturer’s instrutions for available encoder versions see chapters 8.3 – 8.5 A mounted-on handwinding wheel is available with drives models with machine in machine room (TWR). Coupling: Worm wheel and rotor shaft of motor are connected through a flexible, maintenance-free coupling. The coupling half connected to the gear has a sprocket, which transmits the drive movement to the brake rotor of the disc brake. Brake: Note: the brakes of the TW45B machine are intended for static applications as holding brakes. Any dynamic braking is restricted to emergency and test braking. Normal use will not lead to any noticeable wear of lining. These brakes can in no way replace the safety braking systems required for downwards travelling cars. Function: Two different operational brake designs are used with TW45B. a) A two-surface disc brake with radial armature base plate designed for version with machine in machine room (TWR). Two independently operating radial armature base plates press onto the brake lining of the rotor. The disc moves on the hub, forces the friction lining onto the gear housing and is thus stopped. b) A two-surface disk brake with two brake rotors in tandem arrangement for version with machine in shaft (MRL). Two independently operating armature base plates with preset spring resistance press onto the brake lining of the rotors. The two discs move on the coupling hub, force the friction lining onto the bearing cover and armature base plate and are thus stopped. The torque of the two spring-operated brakes has been adjusted at the factory and shall not be re-adjusted. The braking force is adjusted in such a way that one brake shoe con stop the car loaded with full loading capacity. The disc brakes are released through electrically-operated magnetic clamps. Manual release of brake is only possible with machine in machine room (TWR). The brake release levers at transition motor-gear (fig. 1, pos. 11) must be operated. When the brake release levers are pressed, the armature base plate and the rotor are separated. (fig. 25, pos. 5) The rotor is connected to the motor and the worm shaft through a toothing system; the brake is released. Tooth system for vertical motor position Drawing and important manufacturer’s instructions related to installation and details see chapter 8.2.1.

2. PRODUCT DESCRIPTION

Note: TW45B machine for placement in shaft (MRL) does not have mountedon brake release levers. Manual release of the brake is not possible!

Emergency braking system NBS: The optional NBS emergency braking system protects the elevator car travelling upwards from overspeed. Description and details of the emergency braking system see operating manual NBS. Traction sheave: The one-piece (rim and hub) traction sheave is fixed using a cone and a mounting plate overhanging the shaft drive. Further details see chapter 2.4 Technical data. Pulse generator: An overview of pulse encoders used incl. technical data see chapter 8.3 and manufacturer’s instructions in chapters 8.4 – 8.5. Environmental conditions: Surrounding at the final site of the drive (humidity, temperature) shall comply with the requirements for machine rooms (between +5° and +40° C according to EN81.) Relative humidity of air shall not exceed 70%. Attention: the torque of the two-surface disc brake can intensively drop by dewing in case of temperature around or under the freezing point. There is the danger that friction linings seize up at the friction surfaces in case of standstill for longer time. The user of the assembly must provide proper counter measures.

Before testing: • Inspection signs must be made available at the landing doors during inspection work at the lift. • Close the doors acc. to the rules. • Make sure that the car is empty. • The car must be at least two landings below respective terminal landing (seen from run direction). Car empty ➾run direction up; Car loaded with rated load ➾run direction down. • The single brake circuits are tested by energizing the single brake coils with 90 V / 45 V excitation / withstand voltage. When a single circuit is tested, the brake of the 2. brake circuit must be released during the braking process. Therefore, the magnet coil of the 2. brake circuit is energized with withstand voltage. Attention: should the lift move after release of one brake circuit or not decelerate sensibly during the braking process, the energized coil must be switched off immediately. The dual circuit braking function is not guaranteed. Check brake ! Test sequence: inspection of the brake deceleration to be made for each brake circuit individually • Connect deceleration measuring device • Activate normal run (brake to be tested is released) • Activate emergency stop as soon as rated speed is reached (brake to be tested closes) • Determine deceleration for 1. brake circuit using a measuring device • Compare result of the measurement and reference value • Remove continuous voltage supply at continuously open 2. brake circuit and connect to 1. brake circuit. • Connect test terminal at deceleration measuring device to 2. brake circuit. • Repeat test at 2. brake circuit. Deceleration values: Minimum deceleration for one brake circuit

Simple inspection of brake deceleration without measuring device: (this inspection method only applies to travel heights ≥ 7m and control point observable from operation point) Inspection sequence: • The measures described in „before testing“ are to be observed. • Provide terminal for continuous power supply at brake circuit of the 2. brake coil. The car loaded with max. permissible rated load must be at least two landings above bottom-most. • The ropes shall be marked level at control point height. The control point shall be easily visible from the brake operation position. (Marking at bracket height, for example) • Move the car upwards to nearest landing. • Energize 2. brake with continuous control voltage during inspection process. Note: brake shall not be de-energized when the main switch is switched off, as otherwise both brakes will become effective. • Move car downwards at normal speed. Observe control point and ropes from brake operation position. • Switch off main switch as soon as rope marking reaches the control point. • Measure distance between rope marking and control point. This distance is equivalent to the stopping distance of the tested brake circuit. • Compare determined stopping distance and reference value. Stopping distance The max. stopping distance for single brake circuit shall not exceed: In case of installations with VN 1,0 m/s ≥ 1,25 m, with VN 1,25 m/s ≥ 2,0 m (These values apply for simple inspection only) • Disconnect continuous voltage supply and connect to tested brake coil. • Repeat described sequence with 2. brake circuit. Attention: when the brake test is terminated, the original condition is to be established (operation of both brake coils at the same time). b) Inspection of both brake circuits When single circuits are inspected, test of both brake circuits follows by activating emergency stop. The deceleration value must considerably exceed the value measured during single inspection! Remove inspection signs when inspection and service works are terminated.
