Abstract

The problem of stator cooling in a dynamoelectric machine is resolved using manufacturing spaces (32) within stator slots (20) for flow of oil coolant. In order to secure stator winding conductors (30) within the slots, a spring wedge (36) provides a biasing force for biasing the conductors against movements within the slots.
