Abstract

A generator stator core 100 comprises layered sheet segments 400, where each sheet segment in one layer overlaps two sheet segments in an adjacent layer. The sheet segments are securely fixed in radial and tangential directions by dovetail connections 402 comprising wedge-shaped slots 504 running axially at the outer periphery of the stator core. Rails 502 are fitted into slots 504 and are clamped radially outwards against the wedging action of the slots 504 by springs 506. A tool (fig.5c), used in the installing of the springs 506, acts on spring straining elements 510a,b to bring the springs 506 to their strained position (fig.5b).
