Fault Diagnosis Method of Bearing of Asynchronous Motor Based on Wavelet-packet and EMD
In view of the problem that diagnosis effect of traditional fault diagnosis method of bearing of asynchronous motor is bad for local defect and initial fault of bearing, the paper proposed a method of using wavelet-packet theory and EMD to extract fault characteristic frequency of bearing. The metho...
