ABSTRACT:
A rotor of a turbine generator, wherein the field and amortisseur windings are held in place by means of axially and tangentially secured rings shrunk on the rotor body without the use of otherwise customary slot wedges. The rings are shrunk on the rotor body without overlapping and at a distance from each other. In this way, the magnetically effective rotor cross-section is increased up to 30% without reducing the size of the air gap.
