Abstract:
A motor unit according to an embodiment of the present embodiment is provided with a motor, an electric pump for supplying oil to the motor, an inverter unit connected to the motor, a first wire harness, and a second wire harness. The inverter unit comprises an inverter for converting a high-voltage DC current into an AC current and supplying the motor with the AC current, and a control unit for controlling the inverter and the electric pump. The first wire harness electrically connects an external power supply and the inverter unit, and passes a low-voltage power supply line. The low-voltage power supply line is branched at a branch point into a control unit power supply line for supplying drive power to the control unit and a pump power supply line for supplying drive power to the electric pump. The second wire harness electrically connects the electric pump and the inverter unit, and passes the pump power supply line and a pump signal line for transmitting signals between the control unit and the electric pump.
