Abstract
1457485 Cooling dynamo-electric machines WESTINGHOUSE ELECTRIC CORP 19 May 1975 [17 June 1974] 21164/75 Heading H2A In a dynamo-electric machine having a liquid cooled rotor winding 22, coolant is taken to the winding from a distribution chamber 32 and an excitation lead 44 for the winding extends to a position on the side of the chamber 32 remote from the winding, a coolant passage 45 within the lead being there connected to a coolant tube 56 which extends past the coolant chamber from a position on the side of the chamber adjacent the winding. The turbogenerator shown has two diametrically opposed rotor excitation leads 44 connected to respective radial leads 42 which are in turn connected to leads 40 mounted in a bore in the rotor shaft 21 adjacent coolant tubes 26, 28. The coolant in each tube 56 may be passed through a tube 72, Figs. 7, 8 (not shown) in a respective radial lead 42 before being passed to the associated excitation lead 44.
