摘要
随着电机通风量的增大,通风噪声已成为大、中型电机的主要噪声源,并且它在总噪声级中所占的比例也随之增长。本文介绍了关于降低电机通风噪声的试验研究方法及成果,从空气动力方面分析了电机噪声、振动产生的原因。提出了降低电机噪声和振动的有效措施。
with the increasing of various electric machine ventilation the ventilation noise has become main noise source of large and middle motor. Its rate to total motor noise has grown consequently. This paper introduces the experimental methods and results, and analyses the motor vibration and noise by air dynamics method. It gave useful test data and distinct theoretical analysis and effective method for the problem that has been proposed in the paper.
