Abstract

This paper present an optimal torque investigation of outer-rotor hybrid excitation flux switching machine (OR-HEFSM) for in-wheel drive electric vehicle (EV). Previously, most of the successful electric machines for electric drive in EV/HEV is interior permanent magnet synchronous motor (IPMSM) due to their ability to deliver high torque and power densities for great starting and climbing conditions. Nevertheless, the IPMSM has some demerit owing to high volume of permanent magnet (PM) used and unrobustness rotor. As an alternative candidates, flux switching machine (FSM) having robust rotor structure and higher torque capability has been proposed for EV/HEV drive and many research has been reported over the last decade. However, most of them are mainly focused on inner-rotor configuration. Therefore, in this paper the proposed OR-HEFSM is investigated to have maximum performances similar to IPMSM conventionally employed in existing HEV. Several defined parameters of OR-HEFSM are treated using determistic optmization method to attempt maximum torque performance. After several cycles of optimization investigation, the proposed machine has achieved the target maximum average torque and power of 335.08Nm and 160.2kW, respectively.
