<p>A gas cooled dynamoelectric machine is provided that includes a rotor (10) having a body portion (14), axially extending coils (22), endwindings (28), and a plurality of spaceblocks (150, 152, 154, 156, 158) disposed between the endwindings, so that a plurality of cavities (142, 1§44, 146, 148) are defined between mutually adjacent endwindings and spaceblocks. To increase endwinding cooling, at least one of the spaceblocks (150, 152, 154, 156, 158) has a passage (160, 162, 164, 166, 168, 170, 172, 174, 176, 178, 180, 182, 184, 186) extending between first and second adjacent cavities to provide for cooling flow communication between the first and second cavities through the spaceblock. A flow deflector (188, 190) is preferably provided adjacent a radially inner end of one, the other, or both of the cavity facing surfaces of the spaceblock for directing flow into or out of the first and second cavities, respectively.</p> |
