摘　　要：永磁同步电机的气隙磁密、空载反电动势、齿槽转矩等参数对永磁同步电机的启动性能影响大。对5.5 k W稀土永磁同步电机,通过有限元分析软件进行建模、计算、后处理,可得到电磁场效果图以及计算结果,并进一步研究了永磁同步电机在空载和负载两种情况下的启动性能,对稀土永磁同步电机的设计提供指导。The parameters of permanent magnet synchronous motor（PMSM）, such as air-gap magnetic density,no-load back EMF and slot torque, have great influence on the starting performance of PMSM. For 5.5 k W rare earth permanent magnet synchronous motor, the electromagnetic field effect diagram and calculation results can be obtained by finite element analysis software line modeling, calculation and post-processing, and the starting performance of permanent magnet synchronous motor under both no-load and load is further studied. It provides guidance for the design of rare earth permanent magnet synchronous motor.
