Several Methods on Reducing Electromagnetic Noise of Motor

主要针对电机电磁噪声产生的原因,通过理论分析和计算提出了降低电机噪声的几种方法,并将其应用于生产实践,取得了良好效果。

The noise of motor consists of mechanical noise, electromagnetic noise and ventilation noise, and the electromagnetic noise is the most difficult to be resolved. Therefore, controlling electromagnetic noise is very practical for reducing the whole noise of motor. Based on theoretical analysis and calculation, this paper presents several methods for reducing motor noise in accordance with the main causes of electromagnetic noise. These methods were applied in production practice and have gained good effect.
