Abstract

A metal article, such as a stator core, is formed from a continuous strip of wound sheet stock material including winding slot cutouts. The winding slot cutouts are maintained at a substantially constant width throughout most of the radial extent of the winding slots in the finished article, except that one or more of the first and/or last wound layers (i.e., the radially innermost and radially outermost layers) may define winding slot cutouts that are wider than the other winding slot cutouts. Several radial layers may define cutout widths that are progressively expanded such that the resulting winding slot has terminal ends with edges that defining a stair-step profile that approximates a "radiused" or rounded edge. This rounded edge profile protects windings projecting radially into or outwardly from the winding slots near the edge of such slots.
