Abstract

PURPOSE: To make a rotary electric machine compact as a whole and reinforce a fan integrated with an electroconductive ring, by providing a separate stator to drive the fan, placing the stator in a casing and setting the fan in face of the stator.
CONSTITUTION: A stator 15, which is separate from the stator 8 of a main rotary electric machine and acts to drive a cooling fan 14, is mounted on the peripheral surface of a support part 18 or the like in a casing 2. The cooling fan 14 is movably fitted with a clearance X on a shaft 4 and is so supported by a bearing 19 that the fan can be rotated independently of the shaft. The fan 14 is made from a non- magnetic substance such as aluminium or synthetic resin. The part of the fan 14 facing the stator 15 is integrated with an electroconductive ring 23. As a result, the driving section for the fan 14 is housed in the casing 2 and the rotary electric machine is made compact as a whole. The fan is reinforced by the ring 23.
