Electric tricycle motor fault detection

Measure the contacts of the battery box, you can immediately judge the failure of the car not turning due to the power supply. If there is no voltage display, turn on the power lock, and the indicator light of the instrument panel does not light up, it is determined that the fuse of the fuse is broken, the fuse should be replaced, the wire has fallen off, the welding head is broken, or a new wire should be replaced. If there is a voltage display, turn on the power lock, and the indicator light on the instrument panel does not light up, it is determined that the power lock is broken, and a new lock can be replaced without power. If the car still does not turn, use a good speed-adjusting handle to replace the original handle. If the car rotates, it is determined that the original speed control handle is broken, causing the electric tricycle not to rotate, and a new controller should be replaced.
Use the electric tricycle tester to test the voltage of the motor leads, and the fault of the line and control line can be judged immediately. If the measurement result is voltage, it is determined that the motor is broken or the lead wire from the controller to the motor is open circuit fault, which should be eliminated. If there is no voltage in the measurement result, it is determined that the control circuit is faulty, and the next step should be checked. Disconnect the brake plug of the controller, and then turn the electric switch. When the car rotates, it is determined that the brake switch is broken and a short-circuit fault has been caused, and a new brake switch should be replaced. If the motor rotates with low noise when riding, and rotates and stops flexibly, and the motor rotates powerfully and rotates quickly when idling, then the quality of such a motor is good; touch the surface of the motor after riding, if the temperature of the motor is too high after running, then if If it is not your operation or the road has slopes, you should pay attention, it is likely that the motor design of the electric tricycle is faulty.
