Describes wavelet analysis of second generation and superiority of wavelet entropy extracted,and for fault feature extraction of induction motor,the entropy feature extraction methods based on second generation wavelet analysis methods was proposed.While for mixing phenomenon of second generation Wavelet analysis,the signal is filtered through FFT before energy is extracted,which is proposed.Experimental results show this method is very effective.
