Compensated Repulsion Motor – Construction and Working Principle:
Compensated Repulsion Motor is a modified form of the repulsion motor. It is provided with an additional winding, called the compensating winding, to improve power factor and provide better speed regulation. This winding is much smaller than the stator winding and is usually wound in the inner slots of each main pole and is connected in series with rotor through an additional set of brushes placed midway between the usual short-circuited brushes, as illustrated in Fig. 1.47.
