| 摘 要： | 用Morlet小波作为小波基，对异步电动机鼠笼转子故障时的定子电流信号进行多尺度分析，将获得的小波变换系数用等高图表示，从中能清楚地识别出异步电机鼠笼转子不同断条的故障。较基于傅立叶变换的故障诊断，该方法对异步电动机故障的辩识能力有显著提高。

| Abstract: | In this paper the multiresolution analysis of wavelet transform is used to diagnose the fault of broken rotor bars of the induction motor Morlet wavelet is chosen as wavelet base The results of diagnosis are shown to contour map From the maps,the faults of broken rotor bars of the induction motor are identified clearly Contrast to the conventional Fourier transform,this method increases obviously the identify ability for the fault of the induction motor |
