Abstract

A method of forming an edgewise wound core from a lanced strip of generally thin ferromagnetic material having a yoke section, a plurality of teeth extending generally laterally from the yoke section on a plurality of preselected pitch axes, and a plurality of arcuate edges intersecting with each other on the yoke section facing generally opposite the teeth. In practicing this method, the lanced strip is deformed into a plurality of helical convolutions, and the helical convolutions are accumulated in a generally axial stack with the arcuate edges and teeth extending generally radially outwardly and inwardly of the stack. The teeth and the arcuate edges are respectively aligned generally in axial row formations thereof across the stack, and the teeth and the intersections between adjacent ones of the arcuate edges are disposed generally in radial alignment with each other on the pitch axes of the teeth, respectively.
