In order to improve the performance of Wound Field Synchronous Motor (WFSM), Permanent Magnet assisted(PM-assisted) WFSM is proposed and investigated in this paper. The effects of the inserted permanent magnet are increase of the air gap flux and mitigation of the magnetic saturation of iron core. The increase of the air gap flux and mitigation of the magnetic saturation leads to increase torque. Therefore, the torque of PM-assisted WFSM is improved. To verify the torque improvement, the most effective position of the permanent magnet insertion in PM-assisted WFSM is decided by comparing average torques in PM-assisted WFSM with the original one. The torque is calculated by 2-D finite element analysis. With the result, the PM-assistance is applied to a WFSM designed for Electric Vehicle traction motor. By comparing the results of simulated average torques of the original WFSM and the PM-assisted WFSM, the improvement of the torque is figured out.
