Abstract

Research and development of hybrid electric vehicles (HEVs) which integrate battery-based electric motor with conventional internal combustion engine (ICE) has flourished since the last decade given their commitment in reducing green house effect and global warming. Although IPMSM is deemed as an effective electric motor used in HEVs, it’s have some limitations such as distributed armature windings, uncontrollable permanent magnet (PM) flux, and higher rotor mechanical stress remain to be resolved. A new candidate of hybrid excitation flux switching motor (HE-FSM) at various rotor pole number such as 6S-4P, 6S-5P, 6S-7P, 6S-8P, 6S-14P, 4S-4P, 4S-6P 4S-8P and 4S-10P E-Core HE-FSMs, built on concentrated armature and DC field excitation (DC-FE) coil windings, variable flux capability with robust rotor structure which is suitable for high-speed operation is proposed and examined in this thesis. In this research, a commercial FEA solver, JMAG-Studio 13.0 released by JSOL Corporation, is used for 2D-FEA. JMAG was released as a tool to support design for devices such as motors, actuators, circuit components, and antennas. Design feasibility studies of E-Core HE-FSMs and deterministic optimization method have been applied to improve the proposed machine. The goal of this design is to achieve torque and power higher than 303Nm, 123kW and 101Nm, 41kW for three-phase and single-phase, respectively, so as to compete with the IPMSM commonly used in HEV. As a result, the maximum torque and power of the final design three phase and single-phase E-Core HE-FSMs are 313.29Nm, 260kW, 233Nm and 43.42kW respectively. Positively, the proposed HE-FSM has proved to be a good candidate for efficient and safe HEV drive.
