An injection shuttle system is disclosed for fabricating stator core assemblies. Injection tooling and a stator core are selected and positioned on a shuttle means at a selection station for moving to coil loading stations and a transfer station. The injection tooling is positioned, aligned and manipulated relative to a winding machine at each coil loading station for disposing winding turns thereon. At the transfer station, the injection tooling is transferred to a wedge guide housing of a turntable arrangement which includes wedge making and injection stations. A stator height adjustment arrangement is provided for adjusting the wedge making and injection stations in accordance with the axial length of the core. The injection tooling is moved or indexed to the wedge making stations where insulating wedges are fabricated and inserted into wedge guides of the wedge guide housing. The injection tooling is then moved to the injection station where the core is interfitted with the tooling by a core transfer assembly. An injection mechanism at the injection station then injects or transfers the winding turns and insulating wedges into axially extending slots of the core. The end turns of the windings are then moved away from the bore of the core by an end turn separator. The injection tooling with winding turns removed therefrom is indexed or moved to an unloading station where it is transferred from the turntable arrangement to a shuttle means for subsequent transfer back to the selection station.

Methods and apparatus for placing windings in stator core slots and coil

Injection shuttle system

Methods and apparatus are disclosed for fabricating dynamoelectric machine magnetic stator assemblies. Coil injection tooling or tool pack is moved into an alignment position at a winding station where it is manipulated to dispose winding turns directly on the tool pack. The tool pack with winding turns thereon and a magnetic core are moved to a loading station where both are positioned and aligned on a transporting device. A conditioning arrangement adjusts the transporting device and simultaneously adjusts an injection machine for the particular stator core height. The transporting device is then moved and aligned at an injection station where the injection tooling is transferred from the transporting device to a coil injection machine. The magnetic core is aligned with the transferred injection tooling and then the injection machine is activated to cause simultaneous insertion of the winding turns and insulating wedges into axial slots of the magnetic core with the core being retained in position during the coil injection operation by core abutment means located on the core support. The transporting device is again moved to receive the empty blade pack or injection tooling as it is ejected from the injection machine. The magnetic core and the tool pack are moved by the transporting device to an unloading station where both are removed from the transporting device with the empty tool pack being transferred back to the coil winding station for a repeat of the above-described cycle for fabricating another stator core assembly.

Motor manufacturing method, system and method, system and components

Methods and apparatus for selecting increments of relative travel of portions of at least one coil insertion apparatus in response to the actual height of a selected magnetic core and interdependently adjusting the mechanical interrelationships between two or more parts of winding turn establishing means of winding apparatus so as to provide one or more turns of conductive material having a size and shape that is particularly adapted for placement in slots of the selected magnetic core. During the interdependent adjustment, one or more additional coil insertion apparatus may be interdependently adjusted. In one approach, a gauge measures actual axial length of core and mechanism concurrently sets up winding size determining means. The gauge may be coil insertion apparatus. Also disclosed are apparatus and methods for: adjusting winding turn size (this being related to stack height); for adjusting the 'span' of winding turns so that they may selectively be of 'odd' or 'even' span; and for selectively determining relative angular indexing of winding turn receiving means so that the polar axes of adjacent coil groups may be angularly displaced substantially any desired amount. Winding apparatus includes winding turn size determining means that are made up of a plurality of parts, at least some of which are movable relative to one another so as to provide winding turns of a desired span and size.
