Abstract

In this paper, a new analytical model of electromagnetic vibration has been proposed to research the method of vibration and noise reduction. Vibration and acoustic noise characteristics of two typical motors at high speed are also measured and numerically analyzed. Moreover, the influence on the motor vibration characteristics exerted by current harmonics which are generated by the carriers at different frequencies are researched. The results have validated the good consistency among the electromagnetic vibration model, modal analysis and experiments.
