ABSTRACT:
Method and apparatus for forming motor winding conductors rectangular conductor wire. The method comprises populating with hairpin shaped conductors, most of a forming fixture having a plurality of pockets distributed in equal number in one or more pairs of adjacent circles, each concentric with a center of the forming fixture, at least one member defining each of the pockets in one of each pair of adjacent circles being rotatable, at least through a limited angle, with respect to a member defining the pockets in the other of the respective pair of adjacent circles, the hairpin conductors each having first and second legs integrally joined by a loop at one end thereof, with one leg of each hairpin conductor in a respective one of the pockets in a pair of adjacent circles, and rotating in a first direction, relative to each other, the members defining the pockets in each pair of circles through a predetermined angle, to permanently separate the two legs of each hairpin conductor without substantial rotation of each leg of the hairpin conductors relative to its respective pocket. Various additional features are disclosed.
