Abstract: In order to improve the output electromagnetic torque of the SRM and reduce its torque ripple from the perspective of rotor geometry improvement and parameters optimization, a parameter optimization method of a segmental rotor mutually coupled switched reluctance motor (SRMCSRM) based on a modified tabu search algorithm (TSA) was presented. The finite element (FE) simulation models of a 6/4 threephase conventional rotor SRM and a SRMCSRM with a size of Φ160×L70 mm were built. The simulation results in the static field were computed and the influence of structure parameters on output torque was analyzed. The performances of the two SRM types were comparatively analyzed. And a modified TSA based optimization method was used to optimize systematically the structure parameters of the SRMCSRM. It improves the performance of the SRMCSRM and greatly shortens the optimization calculation time.
