| Summary: | Permanent magnet flux switching machine
(PMFSM) with additional coil excitation has several
attractive features compared to interior permanent magnet
synchronous machines (IPMSM) conventionally employed
in HEVs. The variable flux control capability and robust
rotor structure make this machine becoming more
attractive to apply for high speed motor drive system
coupled with reduction gear. This paper presents an
investigation into design possibility and parameter
optimization study of 6-slot 5-pole PMFSM with hybrid
excitation for traction drives in HEVs. The design target is
the motor with maximum power more than 123kW and
maximum power density more than 3.5kW/kg. A reduction
of permanent magnet material for a given torque
requirement and an extension in speed and torque ranges
are chosen as the optimization indices. The designed motor
enables to keep the same power density in existing IPMSM
installed on a commercial SUV-HEV. |
