Abstract
An improved generator rotor () and a method of repairing an existing generator rotor () are disclosed. Methods consistent with the present invention provide techniques for repairing existing stress-damaged rotors () to remove stress-induced cracks (), without requiring new retaining rings (), to significantly extend the useful life of a generator without the cost and complexity of conventional repair techniques. Improved generator rotors () consistent with the present invention provide a tooth-top design that is more resistant to stress-induced cracking than conventional designs, resulting in new generators with longer useful lives.
