摘　　要：为提高电动汽车驱动性能,以电动汽车驱动系统要求为目标,进行永磁同步电动机功率、电枢直径、计算长度和转子结构参数设计,并进行场路结合设计计算。利用以上参数设计了电动汽车用永磁同步电动机样机,进行了驱动电机系统台架试验。实验结果表明,永磁同步电动机低速转矩大、恒功率区宽、温升低,满足电动车的需要。In order to improve drive performance, presented design method of PMSM used on electric vehicle （EV）. According to the driving system requirement, the needed efficiency of PMSM was calculated. The diameter and length of PMSM armature were selected. The field-circuit coupled design were calculated. Based on all above parameters, PMSM used on EV were designed. PMSM was tested on motor test bench. PMSM had big torque at low speed, wide constant efficiency section and low temperature rising. All the performance satisfied the EV requirements.
