Abstract :
In this paper, a segmental SRM and its performance optimization via making some changes on its rotor is investigated. These changes not only reduce the torque ripple, but also increase the efficiency of the motor. Motor has two types of poles on its stator: main and auxiliary. The auxiliary poles make the flux path shorter and eliminate flux inversion on stator. Different types of notches on rotor structure are examined and the best one is chosen. For simulations, finite element method is utilized.
