How Do Battery Electric Locomotive Save Energy And Reduce Emissions?

Energy saving and emission reduction is the main direction of current development, and saving energy consumption of power grid is the most important. About 60% of the electric energy produced in our country is consumed in various types of motors every year, so the explosion-proof battery electric locomotive with high efficiency and energy saving has great application value. At present, most of the domestic mine electric locomotives are based on the power transmission system of induction motor and reducer. They narrow gauge locomotive have the shortcomings of high failure rate, low efficiency, high cost, huge volume and large noise.

Compared with induction motors, battery motors do not need reactive excitation current, and can significantly improve power factor (up to 1), reduce stator current and stator resistance loss, and there is no rotor resistance loss in stable operation, thereby reducing or eliminating it. Cooling fan, make the efficiency of induction motor with the same specifications increased by 2-8 percentage points. When the induction motor works under 60% load,narrow gauge locomotive the efficiency and power factor decrease sharply, while the permanent magnet motor maintains a higher efficiency and power factor in the range of 25-120% load. The energy-saving effect of the force index is more remarkable.

Battery locomotive have larger starting torque, which can reach more than 3.4 times. In equipment requiring large starting torque, smaller capacity motors can be used to replace larger capacity induction motors, which can better solve the phenomenon of "big horse trolley" and improve system efficiency. In addition, the volume, weight and material of battery electric locomotive with the same power capacity can be reduced by about 30%, and the power density is higher. Because the motor has the advantages mentioned above, gearless direct drive is easier to achieve.
