Abstract：To tackle the challenge of electromagnetic vibration of surface-mounted high-speed permanent magnet motor，two electromagnetic vibration suppresson methods were proposed to suppress electromagnetic vibration by using surface-inserted rotor and eccentric permanent magnet pole.A 24kW ， 20000r/min （20 surface-mounted high-speed permanent magnet motor was addressed. Firstly，the sources and spatiotemporal orders of the air-gap magnetic field harmonicsand electromagnetic force harmonics were analyzed based on Maxwellstress tensor method. Next，the effects of surface-inserted rotor structure under different pole embraces and eccentric permanent magnet pole under diffrent eccentric permanent magnet pole distances on the even multiple electromagnetic force harmonics suppression and torque performance were compared and analyzed to select the optimum structure. Finally，the optimization effects of motor electromagnetic vibration were analyzed based on the harmonic response simulation analysis.The motor vibration test platform was also built and the reliability of simulation results were verified by comparing the measured result with simulation result. The conclusion is drawn that the surface-inserted rotor and eccentric permanent magnet pole have obvious effects on motor electromagnetic vibration suppression.
