永磁同步电机失磁故障检测综述

Review on Fault Detection of Permanent Magnet Synchronous Motor

介绍失磁故障分类和永磁材料的各种特性曲线,分析了电机产生失磁的原因,对国内外已有的失磁故障检测进行分类和比较分析,对基于参数辨识的失磁故障检测进行了多角度研究,最后对失磁故障检测前景进行展望。

This paper introduces the classification of magnetic loss fault and the characteristic curves of permanent magnet materials,analyzes the causes of magnetic loss,classifies and compares the existing magnetic loss fault detection at home and abroad,studies the detection of loss of excitation fault from different angles based on parameter identification.Finally,the prospect of magnetic loss fault detection is prospected.
