Noise Lowering for a Large Variable Speed Range Use Permanent Magnet Motor by Frequence Shift and Structural Response Evaluation of Electromagnetic Forces
2012
According to electrical output up rating of a permanent magnet motor and request to operate for a large variable speed range, resonance between structural natural vibration and electromagnetic force inside the motor can take place and make noise. This paper describes the mechanism of a resonance between them and noise lowering procedure by frequency shift when they are applied to the reluctance torque largely employed new motor named Permanent magnet Reluctance Motor (PRM).
