摘　　要：电动机槽配合和定子模态与电磁噪声关系密切,为有效降低电动机电磁噪声,计算了36/28和36/26不同槽配合的力波阶数与力波频率,并采用有限元计算了定子36槽的模态参数,比较了力波与模态参数。根据二维噪声理论,36/28槽配合从噪声角度来看不如36/26槽配合合理,通过样机试验得到验证,为下一步改进电机设计结构、降低电机电磁噪声奠定了基础。The motor slot combination and stator modes were closely related to the electromagnetic noise,in order to reduce effectively motor electromagnetic noise,calculated the order and the frequency force wave with 36 /28,36 /26 slot combination and the modal parameters of the stator with 36 slots using the finite element,compared the force wave with modal parameters,according to the two-dimensional noise theory,36 /28 slot combination was not as good as 36 /26 slot combination from the noise point of view,this was proved by testing prototype,it establish the foundation for the structure improvement of the motor design to reduce motor electromagnetic noise further more.
