摘要
介绍了电动汽车用电机的基本性能,并从汽车行驶动力学出发建立了纯电动汽车用电动机性能参数的数学模型,探讨总结了对电机基本特性参数的初步确定原则。然后以目前所要开发的一辆纯电动汽车的基本参数及目标性能要求为例,按以上原则确定电机参数并绘制符合要求的电机性能曲线,为电机的快速选择和后续车辆动力传动系统匹配优化提供了依据。
Main functions of motor used on EV are presented,and mathematic model of motor performance parameter is built from vehicle dynamics.The main principle to make certain motor＇s basic parameter is concluded.Taking an EV＇s basic data and objective performance requirement as an example,the motor parameter is confirmed,and appropriate motor performance curve is plotted.This provides a basis for choosing the motor fleetly and the improvement of rear vehicle powertrain.
