Torque Ripple Reduction Methods for an Interior Permanent Magnet Synchronous Generator
Paper in proceeding, 2014
This article presents the effect of different torque ripple reduction methods on the average torque and back-emf harmonics. Two methods are compared. One is skewing the stator of the machine and the other method is using a fractional slot winding for the machine. It has been shown that both methods reduce the torque ripple of the IPMSM by 70% while the impact on the average torque is ignorable. The back-emf harmonics will be also reduced.
