摘　　要：着重研究了永磁电机定子槽口宽度对电磁噪声的影响。通过电磁力解析计算得出电磁力与定子槽口宽度的计算关系。利用Ansoft软件对1台电动汽车用永磁电机进行电磁场计算,求解改变定子槽口宽度对电磁力波的影响,并用ANSYS软件对该永磁电机进行不同定子槽口宽度的2D声场计算。进行了试验验证,仿真计算与试验结果基本一致,可为该类电机削弱噪声设计计算提供参考。The influence of permanent magnet motor stator slot width on electromagnetic noise was focused on.The relationship between electromagnetic force and the stator slot width was deduced by the analytical calculation of electromagnetic force.Electromagnetic field calculation was carried out for a permanent magnet motor for electric vehicle by Ansoft software,so as to solve the change of electromagnetic force wave with the change of stator slot width.At the same time,the 2D sound field of this permanent magnet motor was calculated by Ansys software for different slit widths.At last,experiment verification was performed.The simulation calculation result was basically identical with the experiment.This research could provide reference for weakening noise in motor designing process.
