摘要：
In this article, the working principle of the asynchronous motor and its common failure forms are analyzed and summarized. On this basis, the wavelet change of the application of the asynchronous motor that is carried out. In normal state and failure state, the motor vibration and current signal was reconstruct of the wavelet packet decomposition and single, and the fault characteristic frequency band that is conducted to extract. The characteristics of the normal operation and fault run time spectrum is carried on the detailed comparison. Based on the wavelet packet decomposition and reconstruction of motor fault feature extraction method can effective characterization of failure from the characteristic spectrum reconstruction signal waveform. Thus proves that the method based on wavelet analysis can accurately implement motor fault diagnosis.
