Torque ripple reduction of interior permanent-magnet synchronous motor by pole-shoe shaping and skewing

This paper aims to analytically investigate the torque ripple producing mechanism of interior permanent-magnet synchronous motor considering stator slotting effect and rotor saliency. Based on this analysis, a combination of rotor-design technologies is used to suppress the torque ripple. Taguchi robust design based on orthogonal array is applied to obtain… CONTINUE READING
