Method to reduce torque ripple of permanent magnet synchronous motor
A method named as Magnet Shifting to reduce torque ripple of permanent magnet synchronous motor is disclosed. A way of reasonably choosing the repeating unit of magnetic pole, the shifting ways and the shifting angle calculation of the first and second magnet shifting is described, which are carried on the repeating unit of magnetic poles individually or repeatedly to improve the performance of the motor.
