摘　　要：以TMS320F28035作为控制核心,驱动电动机采用额定电压仅为48 V的低压电机,设计了一套纯电动汽车的电动机控制器及转子磁场定向矢量控制系统。对整个系统的控制系算法进行优化改进,提高了电动汽车安全性的同时,实现电动汽车在运行过程中能提供尽可能大的转矩和达到比较高的效率。A set of controller of pure electric vehicle motor and the rotor field oriented vector control system were designed. TMS320F28035 was taken as the system control core,and the low voltage motor with 48 V rated voltage was used for driving. In addition,the control algorithm of the whole system was improved,to improve the safety of the electric vehicle and electric vehicle in the running process can provide as large torque as possible and achieve high efficiency.
