Five Advantages Of Mine Electric Locomotives

1.mine electric locomotives are suitable for a wider environment.

2. Higher reliability The system mine electric locomotives uses a three-phase AC asynchronous motor. Since there is no coil and reversing copper head on the rotor of the motor, it is not easy to be damaged. In addition, the controller has no contact wear.

3.mine electric locomotives better traction performance at low frequency (1HZ) starting, the starting torque can reach 300% of the rated value, enabling the AC asynchronous motor to reach and exceed the starting torque and traction characteristics of the DC motor, the traction force is ordinary 1.6 times that of DC motor cars. It can meet the maximum starting traction of the locomotive at low speed, which makes the locomotive with heavy load starting powerful and powerful.

4. The climbing ability is stronger. The ordinary DC mine electric locomotives has a climbing ability of 11 inches, and the locomotive climbing ability of the AC variable frequency speed control system is 60 inches. Under the same adhesion conditions, the line slope of the DC mine electric locomotives can not be operated, and the AC traction frequency converter can be operated.

5.mine electric locomotives speed control performance is better with stepless uniform speed regulation, high precision, the lowest adjustable frequency 1HZ, the lowest adjustable speed 0.5r / min.

Mine electric locomotives can preset the speed. Once a certain speed is set, it will not exceed the set value even if it is driven downhill. It can avoid accidents caused by overspeed, and it is safe and reliable. The frequency increase time is 5 seconds, even if the driver suddenly accelerates, the mine electric locomotives still increase to the maximum value in 5 seconds.
