【Abstract】 Aimed at the initial failure of asynchronous motors,this paper puts forward a method of fault detection using maximum-modulus theorem of wavelet transform,which takes typical fault in the asynchronous machine as an example to apply the method of maximum-modulus of wavelet transform to the detection of signal mutational components so as to locate and detect the initial failure of asynchronous motors effectively.The result of experiment shows the feasibility of the fault diagnosis method based on wavelet theorem.更多还原
