Title:
SPRING MOUNTING FOR AN ELECTRIC GENERATOR
Document Type and Number:
WIPO Patent Application WO2000057535
Kind Code:
A8
Abstract:
A support system (50) for an electric generator (10) providing optimal stiffness properties in both the tangential and radial directions. The support system utilizes a tapered spring bar (16, 52) having a larger cross-sectional area at points (32) having high bending moment and a smaller cross-sectional area at points (30) 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 (17) may further be formed from a plurality of laminations (45). The tapered spring bar (16) may be positioned in a radial direction between the stator core (12) and the stator core frame (13). Alternatively, the tapered spring bar (52) may be connected in a tangential direction between the stator core frame (51) and a spring plate (55) extending longitudinally along a perimeter of the frame (51), with the spring plate (55) being attached to a foundation (57).
