| Abstract |
This paper presents a new structure of 12Slot-10Pole field-excitation flux switching synchronous machine (FEFSSM) with all active parts namely field excitation coil (FEC) and armature coil are located on the stator, applied for hybrid electric vehicles (HEVs). The rotor part consists of single piece iron makes it more robust and becoming more suitable to apply for high speed motor drive system application coupled with reduction gear. The design target is the motor with a maximum torque of 210Nm with reduction gear ratio of 4:1, a maximum power of 123kW, a maximum power density more than 3.5kW/kg, and a maximum speed of 20,000r/min with similar restrictions and specifications in IPMSM used for LEXUS RX400h. The deterministic design optimization approach is used to treat design parameters defined in rotor, armature and FEC repeatedly until the target performances are achieved, under maximum current density 21A/mm2 for both armature and FEC. A result shows that the proposed design enables to keep the same power density in existing IPMSM installed on a commercial SUV-HEV. |
