摘　　要：针对交流牵引电机存在电磁噪声过大的问题,提出一种交流牵引电机定子齿部开槽降噪优化设计方法。分析了交流牵引电机产生电磁噪声的根本原因,阐述了交流牵引电机定子齿部开槽降噪的具体设计方法,并对其开槽位置与槽口尺寸参数进行了优化研究,最后采用有限元法对其开槽处理前后的效果进行了对比分析,结果表明:交流牵引电机定子齿部在采用本文提出的开槽降噪优化设计方法处理后,在保持其效率基本不受影响的前提下,其电磁噪声得到了显著下降,取得了较好的降噪效果。Aiming at the problem of excessive electromagnetic noise of alternating current traction motor,a noise reduction optimization design method of stator tooth slotting was proposed.After analyzing the root cause of the AC traction motor electromagnetic noise in non-saturated and saturated states,this paper first expounds the concrete design method of grooving noise reduction for AC traction motor stator tooth.Then,the parameters of slot position and size of notches in unsaturated states are optimized.At last,the finite element method is used to analyze noise reduction effect after stator tooth slotting treatment.The results show that the electromagnetic noise of the stator teeth of AC traction motor is significantly reduced with the slotted noise reduction optimization design method proposed in this paper,and the efficiency is basically not affected,and a good noise reduction effect is achieved.
