In this paper, one new axially laminated-structure ?ux-switching permanent magnet machine (ALSFSPMM) with 6/7 (stator/rotor) poles is proposed. Different from the conventional ?ux-switching permanent magnet machine (FSPMM), the stator and rotor of ALSFSPMM are laminated parallel to the axial direction, which can make full use of PM ?ux linkage, decrease part magnetic saturation, and reduce the iron loss particularly in the range of high speed. By the 2-D model prediction of ?nite element algorithm (FEA), ALSFSPMM has lower cogging torque, stronger ?ux weakening ability, greater torque density, higher ef?ciency, etc., and hence it is an ideal candidate for the drive system of plug-in hybrid electrical vehicle (PHEV).
