Detection and SVM classification of Broken Rotor bars Fault in induction motor using WPA

摘要

The fault of broken rotor bars in a three-phase induction motor is diagnosed by using the Wavelet Packet Analysis. In this paper, Daubechies wavelet is selected as the wavelet base, and the wavelet coefficient is obtained from the current signal of the faulty induction motor. The Energy of wavelet coefficient appears to be a good indicator and useful for detecting different electrical faults and using Support Vector Machines classifier to classify the faults.
