Abstract
Electric motor coils are electrically connected to a power device in an inverter. A conductor for supplying a drive current to the motor coils includes a heat radiating area or other heat radiating member in the wiring path. Thus, the heat from the electric motor is radiated from the conductor in the wiring path. The power device and other components of the inverter can be prevented from being thermally damaged or degraded by the heat transmitted from the motor coils to the inverter through the conductor having higher heat conductivity.
