摘　　要：齿槽转矩最小化是高性能永磁盘式电机设计所追求的目标之一。围绕盘式电机齿槽转矩优化问题,阐述了几种实用且有效的盘式电机齿槽转矩优化方法,并利用三维数值有限元分析软件Ansoft Maxwell模拟计算各优化策略下盘式电机的齿槽转矩。仿真结果表明辅助凸部与辅助凹槽及导磁槽楔结构的增加能大大减小齿槽转矩。Minimizing cogging torque is one of the most significant final goals in designing disc- type permanent magnet motor which has high performance and low cost. Based on the optimum issues of cogging torque for disc- type permanent magnet motor,some effective and practical strategies for optimizing and minimizing the cogging torque were presented.Meanwhile,3D numerical FEM software Ansoft Maxwell was applied to the simulation and computation of the cogging torque for all the referred strategies. As a results,all the mentioned methods have a sharp reduction influence on the cogging torque.
