Abstract

Abstract A method of developing one or more coil groups of electrically conductive wire in a coil group accommodating device such as coil insertion tooling. A coil turn-forming assembly is positioned with a snap-out winding form plate in alignment with a corresponding turn-gauging step and engaging a coil group accommodating device adjacent a turn receiving slot. Turns of wire are generated about the winding form plate and turn-gauging step and received in the turn receiving slot during the generation operation. Thereafter, other snap-out winding form plates are sequentially positioned in alignment with a corresponding turn-gauging step and engaging the coil group accommodating device adjacent corresponding turn receiving slots. The turn generating operation is repeated using each winding form plate and turn-gauging step, with the generated turns being received in the corresponding turn receiving slot during that generation operation. When all the coils for one coil group have been developed in the coil group accommodating device, the coil group accommodating device can be rotated to bring other turn receiving slots in alignment with the coil turn-forming assembly. Then the desired number of operations, as described above, can be repeated to develop, in the coil group accommodating device, additional coil groups. When the coil group accommodating device is coil injection tooling, the developed coils can thereafter be inserted from the coil injection tooling into preselected slots of a magnetic core.
