| Abstract: | This paper analyzes the fault characteristics of electromotor. Based on wavelet packet transform theory which can decomposes the signal into several frequency sections according to the different resolution, the energy characteristics and the algorithm of the fault signal in different frequency sections are presented, a new approach of electromotor fault diagnose is presented to combine with BP neural network. The experiment result proves its validity. |
