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.

Abstract: A synchronous machine includes a rotor ring with salient rotor poles each having a shoe portion and a core portion, with a plurality of gaps between the poles. Liquid cooled field windings are arranged in the gaps surrounding each of the poles. The shoe portions of the rotor poles overlap the gaps by at most 20 percent of the width of the gaps. Within the gaps are T-shaped support members which are keyed into the rotor and which have legs extending between the windings and crosspieces on the outside of the windings.
