Cantilever spring contact for retaining rings on dynamoelectric machine

摘要

In a dynamoelectric generator, a low-resistance electrical contact is provided by a cantilever beam mounted between the outer surface of the rotor body and an overlapping retaining ring. This cantilever beam is part of the wedges in the rotor body and provides a conductive current path for high-frequency eddy currents induced on the surface of the rotor and retaining rings at all operating speeds.
