摘　　要：并励直流电动机因励磁绕组电阻远大于电枢绕组电阻,温升对电机性能的影响较为显著。该文在Mat-lab软件平台下,对并励电动机进行了建模和仿真,着重研究温升导致的电机物理参数和工作性能的变化,结果显示励磁线圈和电枢线圈在温升过程中对电机性能的影响具有"反效果",因此可以选用具有较大温度系数的电枢绕组材料来降低温升的影响。Because the resistance of the field winding is much larger than that of the armature, the influence of temperature rise on the performance of shunt motor is marked. The modeling and simulation in Matlab were presented, and studied that influence on the motor physical parameters and performance by the temperature rise was studied. The results show that it is counteractive on motor performance between armature and field winding among temperature rise. In order to depress the influence, the armature stuffs whose temperature coefficient is large was selected.
