640 静的偏心のある電動機の電磁力・構造振動の数値解析

抄録

There are many harmonic components in the electromagnetic force caused by motors. The harmonic components induce the structural vibration and noise. In this paper, electromagnetic vibration and noise from motor with off-centered rotor are discussed comparing with normal motor in numerical analysis. As a result, harmonic components are increased and the average of vibration is about 1.05 times above comparing with those of normal motor.
