| Abstract: | The common faults of squirrel-cage induction motor and the importance of fault diagnosis are introduced.The electrical and mechanical features of signals are extracted by the modified wavelet packet algorithm.A fault diagnosis method based on wavelet packet analysis of frequency-band energy is proposed.The experiment shows that with this method all the broken bars faults of the rotor can be detected rapidly with high accuracy.This method has high feasibility and extensive applicability. |

| Keywords: | vibration and wave asynchronous motor modified wavelet packet algorithm frequency band energy |
