Abstract
A support system for an electric generator having a tapered spring bar connected between the stator core and stator frame, where the spring bar has a continuously tapered cross-sectional area along its length. The tapered cross-section provides a larger cross-sectional area at points having high bending moment and a smaller cross-sectional area at points having low bending moment. By eliminating material in areas of low bending force, a robust support system having increased flexibility is provided. The spring bar may further be formed from a plurality of thinner laminations, thereby providing the support system designer with an additional degree of flexibility for independently controlling the natural frequency of the supports in the radial and tangential directions.
