1. No power: whether the power system sends power to the power supply of the electric flat cart is generally tested with a test pen. If it does not send power, it will work after power transmission.
2. Lack of phase: the electrical appliances of the main and control circuits of the driving motor are damaged, the line is disconnected or the contact is not good, which will also make the flat car driving motor unable to work normally. In this case, the main and control circuits need to be overhauled. During the overhaul, in order to prevent the motor from being burned due to the lack of phase of the power supply sent to the three-phase motor by the main and control circuits, or the electric flat car driving motor is suddenly powered on and running, resulting in harm, the motor must be disconnected from the power line first, Only supply power to the main and control circuits, then jog the start and stop switches, check and analyze the working conditions of the control electrical appliances and circuits, repair and replace the faulty electrical appliances or circuits, and re test the main and control circuits only when it is confirmed that there is no fault.
