Air cooling turbogenerator of electric machine, invovles applying cold air in duct arranged in air gap and guiding over cooling slits

摘要

The cooling method is carried out, so that further cold air is applied in a duct (9,15) arranged in an air gap (4) and is guided over determined cooling slits (13) radially from the inside outwards through the stator (3). The duct (9,15) arranged in the air gap (4) is accommodated in a slot (7) for the reception of the stator winding (5,6) and is held by a slot wedge (8).
