多相感应电机开路故障下空间谐波磁场耦合对转矩脉动影响的研究

This paper investigates spatial harmonic magnetic field coupling effect on torque ripple for multiphase induction motor under open fault condition. The coupling results in severe torque ripple generated by ellipse asynchronous magnetomotive force, and the current space vectors are utilized for coupling phenomenon analysis in the multiple planes. The optimal current space vector is proposed to achi...
