| Abstract: | Hilbert transform and Wavelet packet analysis methods was applied to eliminate the DC component,solving the problem that it was hard to detect the broken bar failure in the rotor because this default characteristic was buried in the fundamental frequency band.Experiment results proved effectiveness of this method to diagnose the broken bar failure in the rotor. |
