Zhejiang Hangyi Bicycle Manufacturing Company begins from Hangzhou Yuanshi Industrial Co.,Ltd,
City Bicycle Price Factory introduces the reasons why the wheels do not rotate:
1. The faults of electric bicycle motors
If you wake up in the morning and find that the electric bicycle cannot be started, don't worry, first make sure to open the electric door lock when the battery is charged, and use a multimeter to measure the voltage of the motor lead. At this time, you can quickly determine what is wrong with the electric bicycle.
The detailed inspection method is: use a multimeter to measure the DC gear of the controller (2, 3) or the lead of the motor, and turn the speed control knob to measure whether there is voltage, and then you can easily find out the fault.
If the measurement result is voltage, it can be determined that the motor is broken or the lead wire from the controller to the motor is broken; if the measurement result is no voltage, it can be judged at this time: the control circuit of the electric bicycle is faulty.
2. Brake switch and controller
Disconnect the brake power-off plug of the controller, and then turn the power switch.
If the electric vehicle can rotate, it is determined that the brake switch is broken and a short-circuit failure has been caused, and the brake switch should be replaced with a new one;
If the car does not turn, use a good speed control handle to replace the original one. If the car rotates, it is determined that the original speed control handle is broken, causing the electric car to not rotate, and a new controller should be replaced.
3. Battery box contacts
Measure the contacts of the battery box to immediately identify the reason why the car does not turn due to the power supply.
The measuring method is to measure the contacts of the battery box with a multimeter in the DC gear to see if there is a voltage display. If there is no voltage display, turn on the power lock, and the indicator on the instrument panel does not light up, then it is determined: the fuse is broken, the fuse should be replaced, the wire is off, the welding is broken, or a new wire should be replaced;
If there is a voltage display, turn on the power lock, and the indicator on the dashboard is not lit, then it is determined that the power lock is broken, just replace it with a new lock without powering on.
