An improved generator rotor ( 30 ) and a method of repairing an existing generator rotor ( 12 ) are disclosed. Methods consistent with the present invention provide techniques for repairing existing stress-damaged rotors ( 12 ) to remove stress-induced cracks ( 29 ), without requiring new retaining rings ( 16 ), to significantly extend the useful life of a generator without the cost and complexity of conventional repair techniques. Improved generator rotors ( 30 ) 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.
