A Gas Cooled Dynamoelectric Machine And A Method Of Cooling Endwindings In A Dynamoelectric Machine.
Abstract: This invention relates to a gas cooled dynamoelectric machine, comprising a rotor (10) having a body portion (14), said rotor (10) having axially extending coils (22) and endwindings (28) extending axially beyond at least one end of said body portion (14); a plurality of spaceblocks (140, 240, 340, 440) disposed between said endwindings (28); a plurality of cavities (142, 242, 342) being defined between mutually adjacent endwindings (27) and spaceblocks (140); at least one said spaceblock (140) having a radially-extending duct (144, 244, 344, 444) defined therein, said duct (144) extending between an inlet opening (150, 250, 350) and an outlet opening (146, 246, 248, 362, 462). The outlet opening (146) is disposed in a surface of said at least one spaceblock (144) facing a cavity (142) adjacent thereto, said outlet opening (146) being defined in a mid-section lof said spaceblock (140) so as to emit said cooling gas flow generally in a direction of a central region of said cavity (142), said inlet opening (150) is formed on a circumferentially oriented surface of said at least one spaceblock (140).
