Wavelet transform and its application in the fault diagnosis for the open-circuit rotor of asynchronous motor

Abstract：Wavelet transform with the good partial characteristic in time?frequency regions is an effective way to make time?frequency analysis and processing of the signals.It has mainly discussed the basic theory of wavelet transform, and introduced the principle of the diagnosis in the open?circuit rotor of asychronous motor with wavelet transform.The construction of signal detection circuit is given as well.
