摘要

针对傅里叶变换分析方法在永磁同步电机故障检测中的不足，提出了小波包变换分析方法。对永磁同步电机定子电流信号进行小波包分解，分析信号各频段能量特征值。仿真结果表明，小波包变换分析方法能较好地表征定子绕组匝间短路的故障特征。

Fault Detection of Stator Winding Interturn Short Circuit in PMSM Based on Wavelet Packet Analysis

In this paper, the method of wavelet packet transform analysis is proposed, according to the shortcomings of Fourier transform analysis method when the fault detection of permanent magnet synchronous motor(PMSM) is studied. The stator current signal of PMSM is decomposed by wavelet packet, then the signal energy eigenvalues of frequency bands are analyzed. The simulation result shows that the method of wavelet packet transform analysis can well characterize the fault features of the stator winding inter-turn short circuit.
