摘要
本文提出对电气设备噪声进行在线监测和实时故障诊断的概念和研究的必要性，综述了电气设备噪声分析和故障诊断的方法，结合实例介绍了利用噪声频谱分析和模式识别方法进行故障诊断的方案，并指出了深入研究的方向。
A concept of online monitoring and fault diagnosis on the noise of electric machines and the necessity of study on itare discussed in this paper. Methods of analysis and fault diagnosis on the noiseelectric machines are summarized. A par-ticular method using frequency spectral analysis and fuzzy mode identification is introduced, And the deeply studied direction is indicated.
