【Abstract】 Electromagnetic vibration and noise analysis is often required for the design of induction motor. In this paper, a noise analysis and research method of induction motor based on multi-physics field coupling is proposed. The electromagnetic force of induction motor is coupled with vibration and noise by harmonic response analysis, and the electromagnetic vibration and noise of induction motor are solved and calculated. The simulation results show that the proposed method can accurately verified the experimental results very well.更多还原
