Abstract

The effect of electromagnetic and mechanical characteristics in permanent magnet (PM) synchronous machines on noise and vibration is presented. Some mechanisms of electromagnetic and mechanical interaction of the machine resulting in noise and vibration are analyzed and calculated. Computational and experimental results are also compared. Noise and vibration resulting from electromagnetic forces dominates in the noise and vibration of PM electrical machine on rated load. When the exerting force frequencies coincide with modal frequencies of the stator, the motor can generate high noise and vibration peak
