The invention discloses a motor dampness drying handcart. The motor dampness drying handcart is characterized by comprising a chassis vehicle, a frame, push plates, an insulating support column, contact arms, tulip contacts, copper connection terminals, aerial plugs, small cabinet top buses, air switches and aerial sockets, wherein the frame is installed on the chassis vehicle, the push plates are respectively arranged at both sides of the frame, the insulating support column is installed on the frame, the contact arm A', the contact arm B' and the contact arm C' are respectively defined as an A phase, a B phase and a C phase and are provided with the tulip contacts, the copper connection terminal is installed between each contact arm and the insulating support column, and each aerial plug is connected with the corresponding copper connection terminal by virtue of a wire. When being used, the motor dampness drying handcart only needs to be pushed into the cabinet and connected with a motor so as to be connected with three-phase electricity, and the motor is baked by self heating through impedance of a winding, and thus the purpose of drying dampness of the high-voltage motor is achieved. The motor dampness drying handcart has the positive effects of simpleness in operation, time saving, energy consumption lowering, safety and practicability.
