Abstract: A stator core with a directly liquid-cooled stator winding has a plurality of slits axially spaced along it perpendicular to the axis. Each slit contains a plurality of cooling blocks arranged together to extend around the periphery of the core. A substantially annular cooling tube is arranged in grooves in the blocks extending substantially tangentially, and is clamped in these grooves.

Abstract: In a pole system which has damping winding slots, a damping winding is positioned in the slots. This winding is formed of damping rods of electrically conducting material and cooling tubes arranged in the slots. The damping rods are connected outside the slots by short-circuiting rings. Each damping window slot contains at least one cooling tube and two adjacent part conductors. Each part conductor has a groove therein, and a cooling tube or tubes are arranged in the grooves. The part conductors are held in position and wedges inserted into the slots are locked in position.
