Title:
ROTATING ELECTRIC MACHINE INTEGRAL WITH CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/008897
Kind Code:
A1
Abstract:
A rotating electric machine integral with a control device, which is prevented from being subjected to heat from a rotating electric machine body and is capable of satisfactorily cooling the control device. A heat sink (13) is attached to a rear bracket (6) of a rotating electric machine body by a conductive stud (300), and switching elements (12) for a control device (400) are installed on the heat sink (13) with predetermined gaps held in the left-right direction in FIG. 2. The heat sink (13) is cooled by a cooling airflow produced by a fan not shown. The control device (400) is installed on the rear bracket (6), whose temperature rises, with a gap in between, and as a result, the control device (400) is effectively cooled through the heat sink (13) while transmission of heat from the rear bracket (6) is restricted.
