基于Maxwell 2D和Simplorer联合仿真平台,以1台额定功率20 kW的电动汽车牵引用永磁同步电机为研究对象,建立考虑电机饱和问题和损耗影响的电机牵引系统仿真模型。通过分析恒转矩工作区间id=0控制与MTPA控制、高速运行区间id=0控制与弱磁控制的牵引特性,具体对比了电机的磁链、电流、转矩脉动、驱动效率等特性。通过试验测试,验证了仿真方法的正确性,为电动汽车牵引电机调速系统的控制仿真提供了参考。

[Abstract]
Based on the Maxwell 2D and Simplorer cosimulation platform, a permanent magnet synchronous motor (PMSM) for electric vehicle traction with a rated power of 20 kW was used to study the simulation model of the motor traction system which could consider the motor saturation problem and the loss, analyzing and comparing the constant torque interval id=0 control and MTPA control, high speed interval id=0 controled and weaked the magnetic control traction characteristicsspecific comparative analysid of the motor flux, current, torque ripple, drive efficiency and other characteristics. And the correctness of the simulation method was validated through experimental tests, and provided reference for the control simulation of electric traction motor speed control system.
