Abstract :
This paper reports on three unique methods to improve the torque profile of the switched reluctance motor. The improved stages carried out on the electromagnetic analysis of two - dimensional (2-D) finite element analysis via the mesh refinement process is first presented. The study of rotor geometry modifications is the next method; the importance of rotor pole shaping is justified through rigorous analysis. Simulated torque profiles from the rippled to the smoothened are presented. In the third method achieving a smooth torque profile by the introduction of pole shoes in the stator poles is reported
