ABSTRACT:
Methods and apparatus are disclosed for fabricating dynamoelectric machine stator assemblies in which end turns of the different windings are separated by winding end turn insulation. In one disclosed method, a plurality of phase insulators are deformed and constrained in a substantially cylindrical configuration and moved axially into a stator core bore. The phase insulators are moved radially outward of the substantially cylindrical configuration with connectors of the insulators moving into predetermined slots of the core. In one disclosed apparatus, a substantially cylindrical arbor is provided with longitudinally extending grooves therein for positioning and accommodating connectors of the phase insulators. The phase insulators are deformed about a peripheral surface of the arbor and then retained adjacent thereto during insertion of the arbor into the bore of a core. The connectors are aligned and moved from the arbor grooves into predetermined core slots. In another aspect, an ejecting means is also disclosed for engaging and positively moving at least some of the connectors from the arbor grooves and thereby aid the stored energy, produced in the insulators by the deforming, in positioning the connectors within predetermined core slots.
