| 179 | DIE ASSEMBLY AND METHOD FOR MANUFACTURING WOUND MOTOR LAMINATED ARTICLE | US14057440 | 2013-10-18 | US20140209728A1 | 2014-07-31 | Thomas R. Neuenschwander; Barry A. Lee |
| A stator core is formed from a continuous strip of wound sheet stock material, in which the sheet stock material is converted from the sheet stock to a formed material including winding slot cutouts. This strip of formed material is then wound into the stator core, with the winding slot cutouts in the formed material maintained at a substantially constant width throughout most of the radial extent of the resulting winding slots in the finished article. However, one or more of the radially innermost and radially outermost layers may define winding slot cutouts that are wider than the other winding slot cutouts. Where several radial layers are altered in this way, the cutout widths are progressively expanded such that the resulting winding slot has terminal ends with edges that are effectively “radiused” or rounded, thereby protecting windings near the edge of such slots. | ||||||
