The invention provides an inverter unit. According to one mode of the inverter unit, the inverter unit is connected to a motor unit, which is provided with a motor and an auxiliary machine. The inverter unit is provided with an inverter, which converts high voltage DC current into AC current and provides AC current to a motor; a control part, which controls the inverter; an inverter shell, which stores the inverter and the control part; a high voltage connector part, which receives high voltage DC current and provides the DC current to the inverter; a first connector part, which is connected to a first wire extending from an external power supply; and a second connector part, which is connected to a second wire extending from the auxiliary machine. In the first connector part, low voltageelectric power is received from the external power supply. In the second connector part, the signals between the auxiliary machines are sent and received, and driving power is supplied to the auxiliary machines.
