Abstract: A stator lamination for an electric motor includes a plurality of notches extending about an inner periphery thereof shaped to minimize damage to insulation of the conductor during insertion of the conductor into the notches and removal of the conductor from the notches. Each notch includes two side walls which intersect the inner periphery of the laminate at a tapered angle. The side walls each include a cutout shaped to receive a retaining strip or slat therebetween, and the cutouts intersect the walls at tapered angles. The tapered angles are preferably less than about 12.degree. or greater than about 14.degree., in order to prevent the formation of a locking taper.
