Abstract: A generator stator core has a plurality of axially extending radial slots arranged about the periphery thereof with windings in each of the radial slots. At least one adjustable wedge and slide assembly is located in each of the slots, arranged to restrain the windings, the assembly including a wedge component and a slide component which interface along respective sloped surfaces formed on respective sides of each of the wedge component and the slide component. The slide component is formed with a zone of laterally extending, discrete fingers on each side thereof that are angled relative to a longitudinal axis of the slide. The wedge component is slidably received in a pair of dovetail grooves in the radial slot with the slide component located between the wedge component and the windings such that the discrete fingers engage side walls of the radial slot.

Abstract: Resin composition comprising an epoxy resin having an epoxide functionality of at least 2.5, a cycloaliphatic epoxy resin, a phenol-formaldehyde novolac and aluminum acetylacetonate. The resin is heat stable and is suitable for fabrication of resin-rich mica tapes having low reactivity at ambient temperatures for good shelf life stability combined with high reactivity above 140° C. for application in press-cured tapes. The dissipation factors at room temperature to at least 200° C. are less than 3.0%.

Abstract: Novel one part, heat cured pressure-sensitive adhesives capable of bonding metallic and non-metallic materials at ambient temperatures and curing at elevated temperatures to form a bond with very high adhesive bond strengths at temperatures up to at least 160° C. The invention is particularly well suited for use with insulated copper coils in electrical generators and includes both the adhesive compositions per se and adhesive transfer tapes capable of bonding to the copper coils at ambient temperatures upon contact due to the pressure sensitive tack of the adhesive. The transfer tapes can subsequently be cured to a hard, thermoset adhesive with high adhesive bond strength. In applications on insulated copper coils, exemplary one part, heat cured pressure-sensitive adhesives can be used either alone or in combination with a substrate to form single or double-sided adhesive tape capable of securing the generator rotor turn insulation.
