Abstract :This study investigates the effect of rotor geometry on performance in switched reluctance motors (SRM) using models analyzed by the 2-D Finite Element Method (FEM). All models have the same stator geometry, winding features, and air gap, but have different rotor geometries. The SRM model operates at nominal speed of 3000 rpm; with 6/4 pole and 150 W output power. Magnetic model analysis was undertaken for the 3 different rotor models. Electrical performance characteristics; speed, phase current, source current, efficiency, electromagnetic torque, and load torque were determined. Magnetic flux density and flux lines in the stator and rotor and the current densities in windings are presented. The optimal rotor model for SRM was determined by considering electrical and magnetic performance data.
