In this paper, a novel configuration for University of Technology Sydney (UTS) plug-in hybrid electric vehicle (PHEV) is introduced which has only one electric machine functioning as either a motor or generator at a time. For continuous working, more strict requests are made to the drive machine, mainly including good thermal dissipation capability, high torque density, great flux weakening ability, etc. One new laminated structure flux switching permanent magnet machine (LSFSPMM) is proposed in this paper, which stator and rotor are laminated in parallel to the axis. It can make full use of PM flux linkage and reduce the core loss particularly in the high excitation frequency. Based on the 2D model prediction by finite element algorithm (FEA), LSFSPMM has lower cogging torque, higher torque density, greater flux weakening ability, higher efficiency, etc., and hence it can be regarded as one ideal candidate for the UTS PHEV drive system. © 2012 IEEE.
