Abstract
Windage losses in a liquid cooled dynamoelectric machine having a stator 10 including an armature 14, a rotor 20 journalled for rotation about an axis within the armature 14, a pump 50, a sump 56 and a liquid flow path 24 within the rotor 20 are avoided through the use of a first transfer tube 58 connecting the pump 50 and one end 68 of the flow path along with a second transfer tube 92 coaxially surrounding the first transfer tube 58 and connected to the other flow path end 91 and to the sump 56.
