Abstract

Hybrid excitation flux switching synchronous machine (HEFSSM) has several attractive features compared to interior permanent magnet synchronous machines (IPMSM) conventionally employed in hybrid electric vehicles (HEV). Among various types of HEFSSM, the machine with both permanent magnet (PM) and field excitation coil (FEC) on the stator has the advantages of robust rotor structure together with variable flux control capabilities that make this machine becoming more attractive to apply for high-speed motor drive systems. This paper presents an investigation into the design possibility and parameter optimization study of 12Slot-10Pole HEFSSM for traction drives in HEV The research target is to design a machine with reduced amount of rare-earth magnet, a maximum torque of 210Nm, a maximum power of more than 123kW, and a maximum power density of more than 3.5kW/kg. Extensions in speed and torque ranges are chosen for optimization aims. The deterministic design approach is used to treat ten design parameters in an effort to achieve the target performances. As a result, the designed HEFSSM with 0.4kg PM is able to get much higher power density compared to existing IPMSM installed on a commercial SUV-HEV.
