502 偏心のある電動機の電磁振動・騒音の実験的研究

抄録

There are many harmonic components in the electromagnetic force caused by electrical motors. The harmonic components induce the structural vibration and noise. In the paper, electromagnetic vibration and noise from eccentric motor are experimentally discussed comparing with normal motor. As a result, maximum vibration is about 5 times and the noise is about 10 dB above comparing with those of normal motor.
