Patent ID: 7589481

Claim:
A control device integrated dynamo-electric machine comprising: an inverter bridge having a plurality of semiconductor switching elements provided for respective arms thereof; and a plurality of common heat sinks that are provided for the respective arms of the inverter bridge and include the semiconductor switching elements mounted thereto for the corresponding arms for cooling the semiconductor switching elements mounted thereto, the plurality of semiconductor switching elements and the plurality of heat sinks being mounted to the control device integrated dynamo-electric machine, wherein each semiconductor switching element includes a plurality of semiconductor switching devices connected in parallel, and the plurality of semiconductor switching devices of a respective semiconductor switching element are mounted to a respective one of the common heat sinks and are spaced apart from each other, so that each semiconductor switching device is exposed to a cooling air pass within which cooling air generated by rotating of a revolving shaft of the dynamo-electric machine flows in a direction of extension of the revolving shaft and each semiconductor switching device is cooled directly by the cooling air.
