Permanent magnet synchronous machines: Performances during driving cycles for a hybrid electric vehicle application

This paper presents the comparison of three permanent magnet synchronous machines (PMSMs) with concentrated flux, the first two machines with fractional slot windings and the other with distributed windings considered as the reference machine. Therefore, the advantages of PMSMs with fractional slot windings were showed. Then, the computation method of the average copper losses, the average iron losses and the average flux weakening copper losses during the driving cycle of a hybrid electric vehicle (HEV) was presented. Finally, a comparative study during the driving cycles of three machines gives a global view of machine performances assembled for a HEV application.
