摘要

目前，各种异步电动机设备已广泛应用于工业生产领域。准确监测电机电压、电流信号并进行降噪对提高整个应用领域的稳定性具有重要意义。本文简要介绍了传统异步电动机定子电压降噪的原理。提出了一种基于小波变换的异步电动机定子电压去噪方法。它很好地利用了传统傅里叶变换在信号分析中的优点，克服了传统傅里叶变换在信号分析中的不足。最后，通过仿真分析和误差验证，证明了该方法的去噪效果良好。

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.
