摘要

Permanent magnet flux switching machine(PMFSM) with additional coil excitation has severalattractive features compared to interior permanent magnetsynchronous machines (IPMSM) conventionally employedin HEVs. The variable flux control capability and robustrotor structure make this machine becoming moreattractive to apply for high speed motor drive systemcoupled with reduction gear. This paper presents aninvestigation into design possibility and parameteroptimization study of 6-slot 5-pole PMFSM with hybridexcitation for traction drives in HEVs. The design target isthe motor with maximum power more than 123kW andmaximum power density more than 3.5kW/kg. A reductionof permanent magnet material for a given torquerequirement and an extension in speed and torque rangesare chosen as the optimization indices. The designed motorenables to keep the same power density in existing IPMSMinstalled on a commercial SUV-HEV.
