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 (140, 240, 340, 440) disposed between the endwindings, so that a plurality of cavities (142, 242, 342) are defined between mutually adjacent endwindings and spaceblocks. To cool the endwindings, at least one of the spaceblocks has a radially-extending duct (144, 244, 344, 444) with an outlet opening (146, 246, 248, 362, 462) disposed to direct cooling gas flowing therethrough generally in the direction of the central region of the adjacent cavity.
