Abstract
A wound field synchronous machine includes direct oil cooling along a conductive sleeve with elongated semi-arcuate shaped channels which alternate with damper bar channels containing tie-rod supports structures. With a reduction in sleeve thickness permitted by the direct cooling, the overall weight of the machine is reduced.
