摘　　要：通过对电动汽车驱动用永磁辅助磁阻同步电动机的转子磁极结构分析,得出不同转子结构对磁阻转矩的影响,在此基础之上,对电机电磁场、转子结构强度和温度场进行仿真分析。仿真结果表明,永磁辅助同步电机的电磁转矩中具有较强的磁阻转矩分量,电机转矩脉动低,安全性好,性价比高,在电动汽车驱动电机中有良好的应用前景。The rotor magnetic pole structure for permanent magnet synchronous motor used in electric vehicle is analyzed, and the influence of different rotor structures on the reluctance torque is obtained. The electromagnetic field, rotor structure strength and temperature field are simulated. The simulation results show that the electromagnetic torque of permanent magnet synchronous motor has a strong reluctance torque component, low torque ripple, good security, high price-performance ratio, and has good potential applications in driving motor used in electrical vehicle.
