Abstract: A generator stator includes a magnetic core having a plurality of axially extending radial slots arranged about the periphery thereof with stator windings in each radial slot. At least one adjustable assembly is located in an axially outermost end of each radial slot, arranged to apply radial force to the windings in the radial slot, the adjustable assembly including mating wedge and slide components which interface along stepped matching surfaces which lie at an acute angle to a center axis of the magnetic core. The assembly is adjustable in situ to compensate for decreases in radial pressure with time while stepped contacting surfaces of the wedge and slide prevent axial regression of the slide.

Abstract: A generator core end support ring is applied to a generator core support at each of its opposite ends. The ring has circumferentially spaced, radially outwardly opening recesses for receiving ends of wedge sub-assemblies each comprising an end wedge having a tapered underside, a tapered slide, a ripple spring, and one or more of a filler strip. The opposite end of each wedge sub-assembly is received in a dovetail stator core slot. Upon application of the sub-assembly to the armature windings spanning between the tapered end core laminations and the end core support, the ripple spring is compressed such that the sub-assembly applies a radial outward force to structurally support the armature windings spanning between the stator core end supports and the location where wedge-supporting dovetails in the stator core begin inboard of the core end.
