Abstract

1,093,862. Cooling dynamo-electric machines. BROWN, BOVERI & CO. Ltd. Oct. 27, 1966 [Oct. 29, 1965], No. 48247/66. Heading H2A. A turbo-generator comprises a generally cylindrical member disposed between the rotor and stator to isolate the rotor and stator from each other, means for providing a sub-atmospheric pressure in the space between the member and the rotor, and means secured to the inside surface of the member for cooling the outer surface of the rotor. As shown, the cooling means comprises one or more tubes 4 and means such as a distributor chamber 5 and collector chamber 6 for passing cooling water through the tube or tubes. Preferably the tube or tubes are arranged in helical fashion; e.g. a plurality of tubes may be disposed in a multi-thread screw-like configuration. Preferably the tubes are made of a non-magnetic metal of low electrical conductivity, e.g. non-magnetic steel, and the cylindrical member 3 is made of synthetic material. The stator winding 7 is cooled by water introduced at 8 and discharged at 9. The rotor winding is cooled by water introduced into a central bore (not shown) in the rotor shaft 10, and withdrawn at the same end by an annular duct (not shown).
