ABSTRACT:
In a method for manufacturing a lamination for a motor or generator where a plurality of the laminations are used to form a core of the motor or generator, a material strip of electrical steel is provided having a width substantially corresponding to half of an outer diameter of the lamination to be created. Slant cuts are made along the material strip to form trapezoids of substantially a same area. Two of the trapezoids are joined together along a side edge of each to form a hexagon. The lamination is then stamped from the hexagon.
