Claim 0:
1. A motor assembly comprising:
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; wherein
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 includes a low-voltage power supply line;
the low-voltage power supply line includes a branch point at which the low-voltage power supply line is 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; and
the second wire harness electrically connects the electric pump and the inverter assembly, and includes the pump power supply line and a pump signal line to transmit a signal between the controller and the electric pump.
