New Laminated-Structure Flux Switching Permanent Magnet Machine for Plug-in Hybrid Electrical Vehicle with Novel Configuration

摘要

In this paper, a novel configuration for 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 requirements are made to the drive machine, mainly including good thermal dissipation capability, high torque density, and great flux weakening ability. For the limitation of traditional machines, one new laminated-structure flux switching permanent magnet machine (LSFSPMM) is proposed. Different from the common FSPMM, the stator and rotor of LSFSPMM are laminated parallel to the axial direction, which can make full usage of PM flux linkage and reduce the iron loss particularly in the high excitation frequency. By the 2D model prediction of finite element algorithm, LSFSPMM has lower cogging torque, higher torque density, greater flux weakening ability and stronger thermal dissipation, hence it can be regarded as one ideal candidate for the proposed PHEV drive system. More experiments will be included in the full paper.
