Discussion:  The principe of Long shunt compound compound DC generator +ere +ere amost the same in Short Compound DC Generator that if an armature revoves revoves bet+een t+o stationary poes, the current in the armature armature moves in one direction during haf. To produce a steady -o+ of unidirectiona or direct current such a device. t is necessary to provide a means of reversing reversing the current -o+ outside the generator once during each revoution.
