| Abstract: | This paper presented an optimization design method of Combined PM-Reluctance Motor(CPMR) for extending speed range with constant output power used in electric vehicles.Based on the analysis of the hybrid excitation of the PM synchronous motor,optimized length of the permanent magnet and reluctance part is obtained pursuing the minimum inverter ampere rating according to the drive system's actual parameter and speed range.Performance compared with the IPM motor shows that CPMR can satisfy the requirements of the high startup torque and the wide speed range of the EV system and results in improved efficiency and power factor within the whole speed range. |
