摘　　要：概述了异步牵引电机电磁噪声的产生机理,并以某电机为例,通过对电磁力波进行理论分析、仿真分析和噪声试验验证,确定了牵引电机80 km/h考核点的最佳槽配合,对异步牵引电机噪声指标正向设计具有一定的指导意义。Mechanism of generation of the electromagnetic noise in the asynchronous traction motor is outlined,and then,as an example,simulation analysis and noise test verification is performed in a asynchronous traction motor based upon the theoretical analysis on the electromagnetic force wave,thus,the best slot fit for the 80 km/h test point of the traction motor is determined,which has the certain guiding significance for the positive design of the electromagnetic noise index of the asynchronous traction motor.
