Test Specification for Electric Locomotives and Motors

August 28, 2024

With the progress of society, the public's awareness of energy conservation, environmental protection and carbon reduction is increasing, the improvement of battery life, convenient stores to provide battery replacement services and the establishment of charging columns and other favorable conditions, which has prompted the public to accept the purchase of electric locomotives. The general definition of electric locomotives is: Extreme speed of less than 50km/h, on the slope, the maximum slope of the general urban road is about 5 ~ 60 degrees, the underground parking lot is about 120 degrees to the ground, the mountain slope is about 8 ~ 90 degrees, in the case of slope 80 degrees, more than 10 kilometers per hour for the basic needs of electric locomotives. Electric locomotive power system composition is mainly: Power system controller, motor controller, permanent magnet synchronous motor & DC brushless motor, DC power converter, battery management system, car charger, rechargeable battery, etc., Many manufacturers now introduce permanent magnet synchronous motor & DC brushless motor, with low speed and high torque, carbon brush free maintenance, far endurance and other advantages. Both the electric locomotive and the power motor system must meet the Ministry of Transportation light bicycle standards, or relevant regulatory requirements.
