Abstract
An object of the present invention is to improve cooling capability of a bus bar with a simple system.An electric system includes a motor unit including a stator and a rotor, the motor unit being cooled by a refrigerant, an inverter unit that supplies electric power to a winding of the stator, a wiring portion that transmits electric power output from the inverter unit to the motor unit, and a pipe that supplies or discharges a refrigerant to or from the motor unit. The pipe is provided at a position at which the wiring portion can exchange heat with an oily medium cooled by the pipe.
