dc traction motor

基本解释

Combined with the structural parameters of TAO649D traction motor, the mathematic model of the DC motor is built and its speed and current dual-closed-loop system is designed.
结合TAO649D机车牵引电机的结构参数，首先建立了该直流电机的数学模型，设计了该电机的转速，电流双闭环系统。
The intermediate AC voltage of train traction converter is limited to DC 1 500 V(750 V), which is taken as an important parameter in the designs of converter and the capacity of traction motor.
列车牵引变流器的中间直流电压只能取1 500 V（750 V），这对于逆变器和牵引电动机的容量设计是重要的参数；
