Abstract
Abstract Method and apparatus for forming shaped insulators and for developing coil turns into coil groups and inserting the insulators and coils into preselected slots of a magnetic core. The insulators are automatically formed at an insulator-forming station by an assembly including control mechanism for providing a series of insulators corresponding to predetermined slots of the core. Insulator and coil insertion tooling is movable between the insulator-forming station, to receive formed insulators; the turn-forming station, to receive coil turns; and an insertion station, at which insulators and coil turns are inserted from the insertion tooling into the magnetic core. The insulator and coil insertion tooling is mounted for pivotal movement about a horizontal axis so that it swings through a generally vertical plane. The insulator-forming station, the turn-forming station and the insertion station intersect this plane. The turn-forming assembly and the tooling are aligned during coil turn generation and some previously generated turns are received in the tooling as other turns are generated. Also the tooling is rotatable, relative to the coil turn-forming assembly, so that turns for each electric phase may be received in the tooling angularly displaced from other phases. Apparatus has two winding head mechanisms for easily generating turns for two phases from different wire. Insulator-forming control mechanisms can be set so that the insulator-forming assembly will provide insulators in predetermined series which correspond to different series of slots of the magnetic core.
