The failure of the
Used Car power supply is a situation that
Used Electric Car often encounter when they are working. There are many factors that may cause this. Let's talk about the reasons for the failure of the Used Car power supply display information.
1. Low voltage will also cause the Used Car to have no power display information. The motor terminal voltage is more than 10% lower than the rated current, and the motor starting torque is too small, making the electric transport vehicle unable to move and work. During the inspection period, use a multimeter or voltmeter to measure the motor input terminal voltage.
2. Electrical damage, disconnection or poor contact of the main circuit and control system of the permanent magnet motor will also cause the permanent magnet motor of the flatbed truck to fail to work normally due to overvoltage. In this case, it is necessary to repair the main circuit and control system. During the overhaul period, the motor must be burned to prevent overvoltage from the main circuit and control system to the three-phase motor.
3. Check whether the distribution line supplies power to the power supply of the electric flatbed truck. Generally, the electric probe is used for testing. If it is not plugged in, the work will be completed after plugging in.
4. When the permanent magnet motor of an Used Car is suddenly plugged in and causes harm, the motor must be disconnected from the power line first, and only power is supplied to the main circuit and control system. Then tap the run and stop buttons, regularly check and analyze the working conditions of the control electrical appliances and circuits, repair and replace new electrical appliances or circuits with faulty ones. Only after ensuring that there are no problems with the main circuit and control system can the motor be put back online for testing.
