Forces generated during sudden short circuits are restrained by heavy rings used as the basic support. This guarantees uniform stiffness of the end winding throughout operating life. Differential thermal expansion is accommodated by means of an elastic end winding suspension. This makes these generators particularly suited to variable load operation or frequent starting and stopping. Rotor The rotor body is a single heat-treated forging with high strength and high magnetic permeability. The coupling flanges at each end are integral parts of the forging. The centrifugal forces caused by the...
