To reduce energy consumption, the original plant circulating pump motor was changed to dual-speed motors.
为了节能降耗,将原循环水泵电机改为双速电机。

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.
Simulation results indicate that the clutch engaging speed can be accurately controlled by using DC servo motordual closed loop control system. The start quality of Vehicle was improved.
