Abstract
An electrical generator having a keyway for a retaining ring key formed in only the pole portion of the rotor and not in the tooth region of the rotor, and a method of repairing an electrical generator by forming such a keyway. The present invention lengthens the operating life of the rotor by eliminating a stress-concentrating discontinuity and by reducing the loads in the highly stressed tooth region of the rotor.
