摘要
电机噪声源的识别及控制已成为目前电机行业的一项重要研究。介绍了电机噪声源的分类,并对现阶段常用的噪声源识别方法的优缺点进行了分析和比较。重点分析了利用频谱分析法识别噪声源的基本理论和具体实现。实验表明,频谱分析法可以有效地识别电机噪声源。
The problems on motor noise source identification and noise control are discussed in this paper. The sort of motor noise is introduced, and the advantage and disadvantage of some usual noise source identification methods are clarified. As an emphasis, the basic theory and method about spectrum analysis are studied. And the experiment shows that the spectrum analysis method is effective in motor noise source identification.
