纯电动汽车动力驱动系统电动机的选择方法之研究

本文首先介绍了电动汽车用电动机的基本性能,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,其次探讨总结了对电动机基本特性参数的初步确定原则。最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,按以上原则确定出电动机参数并绘制符合要求的电动机性能曲线,为电动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。

This paper first introduced the motor of the electric vehicle＇s basic properties, and established the mathematical model of pure electric vehicle＇s motor performance parameters from the vehicle driving dynamics, the mathematics model of the performance parameters, then discussed the basic characteristics of motor and summarized the initial parameters determination principle. In the end, made an example for a developing pure electric car＇s basic parameters and performance requirements, according to the above principles, determined the motor parameters and draw the motor performance curves, and provided the basis in order to choose appropriate power transmission system.
