主 题:Integral-slot surface-mounted permanent magnet machine multi-objective optimization third harmonic torque vibration
摘 要:This study aimed to improve the vibration and torque of an integral-slot surface-mounted permanent magnet(SPM)machine by optimizing the shape of the harmonically injected permanent magnet(PM).First,the effect of the third harmonic injected into the sinusoidal PM shape on the electromagnetic performance of a 36-slot/12-pole SPM machine was investigated,including the torque performance and vibration *** was found that the Sin+3rd harmonic-shaped PM had a contrary effect on the torque and vibration performance of the integral-slot machine,which improved the torque capability but worsened the vibration ***,the response surface model and Barebones multi-objective particle swarm optimization algorithm based on a trade-off between the average torque and vibration were implemented to determine the optimal harmonic ***,the performances of the optimal Sin+3rd-shaped and eccentric PM machines were compared,showing the excellent torque and vibration performance of the adopted ***,a prototype was manufactured and tested to verify the results of the theoretical analysis.
