摘要

本文对混合永磁记忆电机的磁疲劳进行了理论和实验研究。以某型混合永磁记忆电机为原型，设计实验装置，模拟记忆电机中永磁材料周围的磁场环境。根据实验结果，对PM材料的工作条件和磁疲劳进行了分析。结果表明，铁氧体磁体存在极弱的磁体疲劳。一般来说，PM材料的性能是稳定的。在最坏的情况下，当混合永磁记忆电机在连续调速条件下工作时，磁场调节能力可能会略有下降。

Study of magnet fatigue in hybrid PM memory motors

In this paper, theoretical and experimental studies of magnet fatigue in hybrid PM memory motors are presented. A specific hybrid PM memory motor is used as the prototype, and an experimental device is designed, which simulates the magnetic field environments around the PM materials in the memory motor. Working conditions and magnet fatigue of PM materials are then analyzed according to the experiment results. The results show that very weak magnet fatigue is observed in the ferrite magnets. In general, the performance of the PM materials is stable. In a worst-case scenario, when the hybrid PM memory motors work on a condition of continual speed regulation, the magnetic field regulation capability may slightly go worse.
