Abstract
Centering rings may be used to modify the combined resonance of a rotor and its support assembly to migrate the rotor critical speeds such that they can be engineered out of the rotor operating speed range. The centering rings of the present invention may be useful for any rotating electrical machinery, especially high speed aerospace applications, such as generators and starter-generators.
