摘　　要：为解决轴向磁场永磁同步电机温度过高导致电机运行性能降低的问题,针对电机转子进行了深入研究。先利用Maxwell三维电磁场有限元分析软件建立电机有限元模型,仿真电机磁场分布和气隙磁密波形,并计算平均涡流损耗;采用铜层屏蔽减小转子涡流损耗,并仿真出转子涡流损耗随铜层厚度变化情况。In order to solve the problem that the motor running performance of the axial magnetic field permanent magnet synchronous motor was too high,the rotor of the motor was studied deeply. Firstly,the finite element model of the motor was established by using the finite element analysis software of Maxwell 3 D electromagnetic field. The electromagnetic distribution of the motor was simulated and the average eddy current loss was calculated. The eddy current loss of the permanent magnet had been significantly reduced,and the rotor yoke had no harmonics.
