Abstract
This paper deals with the ripple reduction of the electromagnetic torque developed in IPMSM(Interior Permanent Magnet Synchronous Motor). Generally, torque ripple is an important causes of vibration and noise of motor. For reducing torque ripple in IPM with nonsinusoidal EMF, the optimal current which is able to control maximum torque/ampere is considered to be introduced In the proposed method. The fact of torque ripple being reduced when the optimal current Is used in motor is verified through simulation and experiment.
