Abstract :
Fractional-slot non-overlapping-winding permanent magnet synchronous machine for traction application is designed. Detailed comparison of the performance of electrical machine is provided with and without semi-magnetic slot wedges. Usage of slot wedges brings some efficiency benefits while partially eliminating permanent magnet losses. It however, increases the synchronous inductance which results in lower peak torque but a higher field weakening area.
