Abstract: In this paper, numerical method coupled with a novel model is proposed and applied to permanent magnet synchronous motor with reluctance-torque-assisted, aiming to obtain a motor with high efficiency, low torque ripple and maintain a good saliency ratio. Time-stepping finite-element-method coupled with multi-objective genetic algorithm is used to perform the further optimization. Through the proposed design method, the efficiency of the motor under rated condition will be improved and higher than 92% which can satisfy IE4 standard and the torque ripple is no greater than 5%, which is relatively low compared with the initial design.
