Research and developments on hybrid electric vehicle (HEV)which combined battery based electric motor and conventional internal combustion engine (ICE) have been intensively increased since the last decade due to their promising solution that can reduce green house effect and global warming. Several electric motors under serious consideration for HEV propulsion system at present are dc motor, induction motor (IM), interior permanent magnet synchronous motor (IPMSM) and switched reluctance motor (SRM). Although IPMSMs areconsidered to be one of the successful electric motor used in HEVs, several limitations such as distributed armature windings, un-control permanent magnet (PM) flux and higher rotor mechanical stress should be resolved. In this paper, design investigations of E-Core hybrid excitation flux switching motor (HEFSM) with various slot-pole combinations for hybrid electric vehicles (HEVs) applications are presented. With concentrated armature and field excitation coil (FEC) windings, variable flux capability and robust rotor structure, performances of 6S-4P, 6S-5P, 6S-7P and 6S-8P E-Core HEFSMssuch as flux lines, back-emf, cogging torque, flux distribution, instantaneous torque profile and torque versus speed characteristics are analyzed based on 2D Finite Element Analysis (2D-FEA). The initial design E-core HEFSM with 6S-8P topology has achieved the highest torque and power of 106.7Nm and 35.4kW, respectively.Further design improvements and optimizations will be conducted in future to increase their performances.
