Abstract :
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.
