A gas cooled dynamoelectric machine is provided that includes a rotor having a body portion, axially extending coils, endwindings, and a plurality of spaceblocks disposed between the endwindings, so that a plurality of cavities are defined between mutually adjacent endwindings and spaceblocks. To cool the endwindings, at least one of the spaceblocks has a radially-extending duct with an outlet opening disposed to direct cooling gas flowing therethrough generally in the direction of the central region of the adjacent cavity.
