摘　　要：采用8对极18槽的单盘盘式电机为实验原型,在试验台上测出其能带动的最大负载,定子绕组的最大电流等,并用Ansys公司的RMxprt和Maxwell 3D模型建立永磁同步电机模型,给予电机以电流激励,构建一个完整的仿真系统。通过对PMSM模型的有限元分析,得出反电势曲线,以及随时间变化的输出转矩曲线及电流密度的分布情况。并将仿真结果与试验测试结果相比较。对比结果给盘式PMSM的优化设计及进一步研究提供了依据。Permanent magnet synchronous motor model has been established by using RMxprt and Maxwell 3D models of Ansys. A complete simulation system has been built via giving the motor current excitation. The back electromotive force curve and the distribution of the output torque curve and the current density varying with time have been obtained through the finite element analysis of PMSM model. By comparing simulation results with ex- perimental results, this paper provides further references for disc PMSM＇s optimization design.
