Abstract
The dynamoelectric machine has endwindings 24 including a plurality of superposed conductor bars 22 and adjacent end turns 20. Rabbets 32 are formed along the undersides of the adjoining conductor bars and end turns to receive gussets 30 for reinforcing the joints therebetween. One or more of the conductor bars and end turns have cooling passages 36, 38 with ports 40, 42 opening to one side of the joint at locations short of the joint. A cooling block 48 is disposed on one side of the joint extending between the superposed conductor bars and superposed adjacent end turns and spaced from the joint to define a chamber 60 in communication through the ports with the passages for passing cooling gas therethrough in heat exchange relation to the joint assembly.
