Analysis and Simulation Research on Radial Electromagnetic Force Wave of Permanent Magnet Synchronous Motor

Abstract

Abstract Aiming at the problems of vibration and noise of permanent magnet synchronous motors, based on the principle of radial air gap magnetic density generation, a model of radial electromagnetic force waves is constructed, and the radial air gap magnetic density and diameter of permanent magnet synchronous motors are derived by analytical analysis Analytical expression of the electromagnetic wave, to obtain the main order, frequency and amplitude of the radial electromagnetic wave. Using Maxwell 2D simulation software to establish a simulation model, verify it, prove the correctness of the proposed method, and provide a theoretical basis for further research on the vibration and noise of permanent magnet synchronous motors.
