마그네틱 토크와 릴럭턴스 토크 비율에 따른 IPMSM의 출력 특성에 관한 연구

Interior permanent magnet synchronous motor(IPMSM) has higher power density than other PM (permanent Magnet) machines due to reluctance torque in addition to magnetic torque, and the ratio of magnetic and reluctance torque has influences on motor characteristics such as input current, efficiency, power factor, etc. Therefore, this paper presents the output characteristics of IPMSM according to the ratio magnetic and reluctance torque of IPMSM and discuss the design strategy of IPMSM.
