Mining Equipment factory Introduction The 8T Electric Locomotive controls the motor power by controlling the current, and finally achieves the goal of speed regulation. However, it is unexpected that its current control method is different from that of resistance speed regulation. It changes the average value of motor voltage and current by changing the time ratio of DC current interruption. The car frame is made of high-quality materials, so it has very good stability and durability.
