Patent attributes
A motor assembly includes a motor, an electric pump to supply oil to the motor, an inverter assembly connected to the motor, and a first wire harness and a second wire harness. The inverter assembly includes an inverter to convert a high-voltage direct current into an alternating current and supply the alternating current to the motor, and a controller to control the inverter and the electric pump. The first wire harness electrically connects an external power supply and the inverter assembly, and passes a low-voltage power supply line. The low-voltage power supply line is, at a branch point, branched into a controller power supply line to supply drive power to the controller and a pump power supply line to supply drive power to the electric pump.
