Abstract

Interior permanent magnet motors (IPM) have been widely used in electric or hybrid electric vehicles due to their high efficiency and high power density. Frequent starts and stops, acceleration and deceleration of vehicles present heavy requirements for the drive motor. In this paper, a 4kW interior permanent magnet motor is designed for a small range-extended electric vehicle. A case study has been carried out for a range-extended solar-electric auto rickshaw, which is used extensively in Asian cities for point-to-point transportation with frequent starts and stops. Based on the specifications for the auto rickshaw, the optimal design processes of traction motor has been proposed, which includes specific considerations for determining dimensions of the stator and rotor, selection of slot-pole combination, skewing effect, the structure of rotor and permanent magnets, analysis of the pole-arc to pole-pitch ratio and reduction of active material in the motor. Analytical results obtained are verified by finite element analysis (FEA).

增程电动汽车内置式永磁电机的优化设计考虑

内嵌式永磁电机以其高效率和高功率密度的特点在电动或混合动力汽车中得到了广泛的应用。车辆频繁的启停、加减速对驱动电机提出了很高的要求。本文设计了一种用于小型增程式电动汽车的4kW内置式永磁电机。在亚洲城市广泛应用于频繁启停的点对点交通的增程太阳能电动人力车进行了案例研究。根据机动人力车的规格要求，提出了牵引电机的优化设计流程，包括定子和转子尺寸的确定、槽极组合的选择、偏斜效应、转子和永磁体的结构、极弧-极节比的分析以及电机中活性物质的减少等方面的具体考虑。通过有限元分析(FEA)验证了分析结果。
