摘　　要：牵引电机的矢量控制建立在牵引电机的模型之上,因此电机模型的准确性与控制系统的性能密切相关。文章首先根据电机学基本理论,建立了牵引电机等效电路,再从理论上推导包含杂散损耗的牵引电机等效电路。然后对MJV180-06牵引电机进行测试,并通过试验数据,推导了该牵引电机的等效电路模型。最后对比测试结果,发现牵引电机等效电路中转子电阻和转子电抗是一组变量,由此推测牵引电机存在变化的动态等效模型。The vector control of the traction motor is based on the model of the traction motor,so the accuracy of the motor model is closely related to the performance of the control system.Firstly,the equivalent circuit of traction mo-tor is established according to the basic theory of electrical machinery,and then,the equivalent circuit of traction motor including stray loss is deduced theoretically.Afterward,the MJV180-06 traction motor is tested and the equivalent circuit model of this traction motor is derived through the test data.Finally,it is found that the rotor resistance and ro-tor reactance in the equivalent circuit of the traction motor are a set of variables by comparing the test results,thus,it is speculated that there is a changing dynamic equivalent model existing in the traction motor.
