Modeling and Suppression of Torque Ripple in PMSM Based on the General Airgap Field Modulation Theory

The permanent magnet synchronous motor is the most commonly used motor in servo systems. Torque ripple caused by the variation of the airgap magnetic field limits the steady-state performance of the servo system. In this article, a novel torque ripple model is established based on the general airgap...
