本文首先讨论了笼型感应电动机的电磁噪声和负载噪声的关系及特点，然后论述了控制电磁噪声的若干措施．并首次采用了几种目前不被人们采用和推荐采用的槽配合．设计和制造了低噪声笼型三相感应电动机．给出了电磁噪声的计算值和空载噪声试验结果． This paper firstly discusses the relationship and characteristics between the electromagnetic noise and load noise of cage induction motor, and then discusses some measures to control the electromagnetic noise. For the first time, several types of troughs that are not currently used and recommended for use are used. Design and manufacture of low noise cage three-phase induction motor. The calculated value of electromagnetic noise and the test result of no-load noise are given.
