Electric motor having heat radiator at electric connection with inverter
First Claim
1. An electric motor having an inverter and motor coils electrically connected to the inverter, electric power being supplied from said inverter to said motor coils, said electric motor comprising two conductors respectively connected to said motor coils and inverter, said two conductors being electrically connected to each other through an electrically conductive member having a heat conductivity lower than that of said conductors, thereby transmitting electric power from said inverter to said motor coils through said conductors and conductive member.

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.
