A voltage de-noising method based on the wavelet transform of asynchronous motor stator

At present, all kinds of asynchronous motor equipment has been widely used in the fields of industrial production. Monitoring motor voltage, current signal and de-noising accurately are important to improve the stability in the whole application field. In this paper, the principle about voltage de-noising of traditional asynchronous motor stator is briefly introduced. A voltage de-noising method based on the wavelet transform of asynchronous motor stator is presented. It well makes use of the advantages of traditional Fourier transform in signal analysis and then overcomes the deficiency of it. At last, it shows that the de-noising effect of this method by analyzing the simulation and verifying the error is good.
