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.
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.
A multi-plane adjustable connector facilitates electromechanical connection between armature bar ends in a generator. The connector includes opposing end sections positionable in multiple orientations, and a plurality of interim sections coupled between the opposing end sections. The opposing end sections and interim sections are connected in a series via a plurality of hinges, respectively, where at least one of the plurality of hinges is angled relative to the others.
A segmented stator for a permanent magnet motor. The stator includes a plurality of stator segments forming an annular stator yoke and a plurality of stator teeth extending from an edge of the stator yoke. At least one coupling is between adjacent stator segments and shaped to allow movement of adjacent teeth in a so-called loose tooth design. Slot wedges are located between adjacent teeth to prevent the conductive windings from moving out of the slots through the slot openings. The slot wedges also prevent movement of adjacent teeth with respect to one another. The segmented stator can comprise an annular yoke with a plurality of discrete teeth or a plurality of assemblies including a rim section and a tooth section. The slot wedges can be keyed wedges that maintain their position through interlocking and/or can be integrated with a stator bobbin.
