ABSTRACT:
A rotor of a turbogenerator having direct gas cooling of an excitation winding conductor. An insulating strip is provided between a slot base and the excitation winding conductor. A resiliently elastic intermediate layer, which may be in a form of a corrugated spring, is provided between the insulating strip and the excitation winding conductor in order to compensate for seating phenomena of the excitation winding. This corrugated spring extends in a direction of the rotor body center, originating from the body end. In order to fix this corrugated spring axially without the cross section of the keyway being constricted, the corrugated spring has a pair of projections which point downwards and engage in lateral recesses in the insulating strip.
