摘要
本研究针对永磁直流电机噪声大的问题,使用B&K噪声和振动测试仪确定了低频噪声为电机换向噪声,高频噪声为径向电磁噪声,并从减振的角度提出了具有一定可行性的改善措施。
This research is aimed at the problem of high noise of permanent magnet motor. We use B＆K noise and vibration testing instrument to determine the low frequency noise for the motor commutation noise, high frequency noise for radial electromagnetic noise. Finally, the improvement measures are put forward from the angle of vibration reduction.
