Junction connection piece for hollow strands of the stator conductor bars of a dynamo-electric machine
First Claim
1. In a dynamo-electrical machine of the type wherein the stator winding thereof is comprised of stator bars composed of a combination of solid and hollow strands through which a fluid coolant is circulated and wherein the end portions of the hollow conductor strands of each bar protrude beyond the ends of the solid conductor strands thereof, the improvement wherein said protruding end portions of the hollow conductor strands are grouped together in a conductor bundle and which latter is encased in a cast-on body of synthetic resin that serves as an electrically insulating nipple for connection of the bundle of hollow conductor strands to fluid conduction means for circulation of the fluid coolant.

Abstract
A fluid cooled stator winding of a dynamo-electrical machine is comprised of stator bars each composed of a combination of solid and hollow conductor strands. The end portions of the hollow conductor strands protrude beyond the ends of the solid conductor strands of the bar and are grouped together in a conductor bundle on which is cast a body of synthetic resin that forms a nipple for connection of a hose to the bundle of hollow conductor strands for circulation of the fluid coolant.
