摘要

提出了一种三相线路起动永磁同步电动机在不同程度的静态偏心故障下的检测方案。采用有限元法对不同偏心率的正常和故障LSPMSM进行了数值模拟。进行了精确的实验室测试实验来评估所提出的指标。研究了加载条件对LSPMSM的影响。对定子电流中的故障相关特征进行了识别，提出了一种有效的LSPMSM指标。仿真和实验结果表明，低频分量是检测LSPMSM静态偏心的有效指标。

Analysis of rotor asymmetry fault in three-phase line start permanent magnet synchronous motor

This article proposed a detection scheme for three-phase Line start permanent magnet synchronous motor (LSPMSM) under different levels of static eccentricity fault. Finite element method is used to simulate the healthy and faulty LSPMSM with different percentages of static eccentricity. An accurate laboratory test experiment is performed to evaluate the proposed index. Effects of loading condition on LSPMSM are also investigated. The fault related signatures in the stator current are identified and an effective index for LSPMSM is proposed. The simulation and experimental results indicate that the low frequency components are an effective index for detection of the static eccentricity in LSPMSM.
