Abstract

1,096,208. Cooling for dynamo electric machines. BROWN, BOVERI & CO. Ltd. Sept. 30, 1965 [Oct. 2, 1964], No. 41566/65. Heading H2A. In a dynamo-electric machine, e.g. a turbogenerator, cooling gas enters the hollow conductors of the rotor winding at inlet ducts A, B, A<SP>1</SP>, B<SP>1</SP>, in each end winding and emerges at a region C, C<SP>1</SP> intermediate the ends of the rotor and at least one of the ducts B or B<SP>1</SP> is arranged so that when gas passes through it an injector effect is produced to suck gas through another of the ducts A or A<SP>1</SP> into the winding. The end winding conductors may have thicker walls than the parts of the conductors in the slots so as to enable the inlet ducts B, B<SP>1</SP> to be formed obliquely and give the required gas injection.
