The failure of the Electric Car power supply is a situation that electric tractors often encounter when they are working. For this point, there are many possible factors that may cause it. Let's talk about the reasons for the failure of the power display information of the electric tractor.
1. Low voltage will also cause the Electric SUV Car to have no power display information, the motor terminal voltage is more than 10% lower than the rated current, and the starting torque of the motor is too small, so that the electric pallet truck cannot move and work. During the inspection period, measure the motor input terminal voltage with a multimeter or voltmeter.
2. Damage to electrical appliances, 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 such cases, it is necessary to repair the main circuit and control system. During the overhaul period, the motor will be burned to prevent overvoltage of the power supply from the main circuit and control system to the three-phase motor.
3. Check whether the power distribution line supplies power to the power supply of the electric flatbed. Typically, electrical probes are used for testing. If not plugged in, the job will be done when plugged in.
4. When the permanent magnet motor of the Electric SUV Car is suddenly plugged in and causes harm, the motor must be disconnected from the power line first, and only supply power to the main circuit and control system, then tap the run and stop buttons, and regularly check and analyze the control electrical appliances And the working condition of the circuit, repair and replace the electrical appliance or circuit with the cause of the failure, and only after ensuring that the main circuit and control system have no problems can it be re-tested.
