ROTARY ELECTRIC MACHINE FOR VEHICLES

Document Type and Number:

WIPO Patent Application WO/2005/086322

Kind Code:

A1

Abstract:

[PROBLEMS] To provide a rotary electric machine for vehicles which is mounted on a car, such as an electric car or a hybrid car, wherein the rotary electric device and the inverter unit which controls the rotary electric device are integrated to improve size reduction and torque characteristics and efficiency of the rotary electric device. [MEANS FOR SOLVING PROBLEMS] Since an inverter unit (4) is cooled by cooling wind forcefully produced by a cooling fan (28), the inverter unit (4) is efficiently cooled. Thus, the radiating fins (401a, 402a, 403a) of heat sinks (401, 402, 403) can be reduced in size, with the result that size reduction of the inverter unit (4) is attained and the mountability of the inverter unit (4) onto a rear bracket (19) is improved. Further, since the inverter unit (4) and rotary electric device (2) are cooled by the cooling wind produced by the cooling fan (28), the cooling medium (cooling wind) for the inverter unit (4) is used also for the rotary electric device (2), so that the cooling structure is simplified.
