Abstract
In a dynamoelectric generator, a low-resistance electrical contact is provided by a multilam or belleville spring mounted between the outer surface of the rotor body and an overlapping retaining ring. This contact forms a conductive current path for high-frequency eddy currents induced on the surface of the rotor and retaining rings at all operating speeds.
