Investigations on Switched Reluctance Motors for Automotive Systems

This research article deals with the electromagnetic analysis of switched reluctance motors (SRM) for electrified transportation systems applications. Even though SRM has salient features such as isolated phase windings, no rotor winding, and the absence of a permanent magnet, this motor suffers from high torque ripple. So finite element analysis (FEA) applied to SRM for a different number of phase windings to estimate the motor with superior characteristics. A 60V, 2000 RPM, 12 Nm SRM is considered for FEA. This analysis finds that three-phase winding SRM has a low value of torque ripple, but the average torque is better with seven-phase SRM. So this finds confusion in the determination of the best motor, it is obtained by considering the number of switches required for three and seven-phase SRM as three-phase winding assists SRM.
