Abstract
In a gas-cooled generator or other dynamoelectric machine, the windings mounted in slots in the rotor are provided with a plurality of passages for the flow of cooling gas from the gap between the rotor and stator, diagonally down through the windings, then diagonally back up to the gap. In contrast to the prior art, wherein two ascending passages join at a shared outlet duct to the gap, the separation is maintained herein, by providing a completely separate outlet duct for each ascending passage, for improving the flow of cooling gas through the rotor and into the gap.
