低压三相异步电动机产生噪声的原因及措施

Cause and Control Method of Noise of Low-Voltage Three-Phase Induction Motor

主要介绍了低压三相异步电动机的三种噪声类型及产生的原因,重点阐述了电磁噪声的抑制方法,经实例验证该方法切实可行。同时也提出了机械噪声和通风噪声的解决措施。为安装问题提供了可靠的参考依据。

This paper chiefly introduces types and causes for three kinds of noises of low- voltage three-phase induction motor, and emphatically introduces suppression method of electro- magnetic noise. The practical example has verified that this method is feasible. Solutions of me- chanical noise and ventilation noise are presented at the same time. It can provide good refer-enee.
