径向磁路永磁同步电机转子损耗的实验研究

The Research on the Rotor losses of Radial Magnetic Path for Permanent Magnet Synchronous Motor

对变频电源驱动的径向磁路永磁同步电机的转子损耗问题进行了实验研究。实验结果表明电枢绕组谐波电流是产生该电机转子损耗的主要原因。文中对减少转子损耗提出了几项措施。

The rotor losses of radial magnetic path for permanent magnet synchronous motor are studied in this paper. The experimental results are presented to show that the rotor losses are mainly caused by stator harmonic current. Finally, some methods to reduce the losses are given.
