Abstract

1432837 Cooling dynamo-electric machines LENINGRAD ELEKTROMACHINOSTROITEL OBIEDINENIE ELEKTROSILA Im S M KIROVA 16 May 1973 23232/73 Heading H2A The directly liquid cooled winding of a cylindrical rotor for a synchronous electrical machine comprises, for each pole, two groups of concentrically arranged coils 1, 2, 3, 4 and 5, 6, 7, one group being superimposed upon the other in slots in the rotor core, the lead-outs 14, 15, 16, 17, of all coils being arranged at one axial end of the core and being hydraulically and electrically connected together such that all the coils of each pole are hydraulically connected in parallel and electrically connected in series with one another.
