Abstract
Windage losses in the air gap of a dynamoelectric machine and normally associated with direct contact liquid cooling are avoided through the provision of a first weir (flange) radially inwardly of rotor conductors and a second weir radially and axially outwardly of the first weir which provides a fan-like spray of coolant on stator end turns at a location remote from the air gap.
