Optimal design of saturated switched reluctance machine for low torque ripple and high average torque

A switched reluctance motor has been one of possible candidates of rare-earth-free-motors. This paper focuses on the optimal design method of switched reluctance machines (SRMs) for mitigating torque ripple and improving average torque under the low speed operation. In order to improve the startup performance of micro electric vehicles (EVs) and reduce the converter capacity, a SRM with four times overload torque is required.
