Multi-winding on/off drive

Speed regulation is achieved in different modes according to the cost and performance of the final application where the motor is used. The stator coil is divided into 3 or 4 pairs of windings. The speed is adjusted stepwise by connecting different combinations of these windings to the main through AC switches in order to change the number of active stator poles and the base speed.
