摘　　要：以轴向磁场磁通切换型永磁电机为例,提出一种基于永磁磁通幅值的电机外围漏磁有限元处理方法,即电机有限元模型外围空气罩尺寸的确定方法。研究表明该方法可以在计算时间和精度之间实现最优化,同时可以推广到双凸极电机等定子永磁型电机的有限元分析。Taking an axial magnetic field flux-switching PM machine as example, a finite element processing method of peripheral flux leakage is presented on the basis of PM flux amplitude in this paper, i.e. the method to determine the size of peripheral air cylinder of finite element model. Study shows that a balance between the calculation precision and time can be achieved. This method can also be extended to the finite element analysis of stator PM motors such as doubly salient motor, etc.
