Abstract: Dynamoelectric machine stator assemblies are disclosed in which end turns of the different windings are separated by winding end turn insulating portions of a plurality of individual phase insulators. The end turn insulating portions of the phase insulators are disposed in overlapping pinwheel configuration with overlapping portions of the insulators being disposed adjacent each other along the entire extent of the overlap.

Abstract: Dynamoelectric machine stator assemblies with new and improved winding interconnection arrangements are disclosed. Windings are disposed in slots of a magnetic core with end turn portions thereof disposed adjacent a core face. The winding end turn portions are compressed and shaped to receive and support a connection insulator. A connection insulator comprising a plurality of holsters contains tap wire connection points and is located within a deformed section at the outer peripheral surface of the winding end turns. The connection insulator is retained in position by a retention means and secured to the winding end turns by lacing material.

Abstract: An insulated internal connection arrangement between a terminal end of a winding of a dynamoelectric machine and at least one other wire conductor is disclosed. The connection arrangement includes an insulator having at least one elongated generally tubular receptacle with one end thereof open and the other end closed and having an internal restriction between the open and closed ends. A connector disposed within the at least one receptacle, electrically joins winding and wire conductor ends. The connector has a flared portion which cooperates with the internal restriction to firmly capture the connector within the receptacle. The insulator may include a plurality of receptacles formed from a single sheet of insulating material with the receptacles disposed generally coplanar and with each receptacle opening in the same direction. The internal restriction may comprise a depression extending transverse to each of the receptacles.

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.

Abstract: Dynamoelectric stator assemblies and methods of fabricating stator assemblies with new and improved winding interconnection arrangements are disclosed. In one disclosed method, windings are generated and disposed in slots of a magnetic core with end turn portions thereof being disposed adjacent a core face. At a tap insulating station, selected winding tap wires are insulated and routed to a common connecting region. The core with winding turns therein is then moved to an end turn pressing station to compress and shape the winding end turns and to condition the end turns to subsequently receive and support a connection insulator. At a connection station, a tap support and aligning means is interfitted with the core for receiving the tap wires and lead wires therein.
