Abstract: Energy efficiency of electric motors and transformer, inductor and ballast apparatus is increased through use of amorphous ferromagnetic materials and thin section electrical steels by methods using folding of lamination stock, forming of lamination stock after folding or punching, and stacking to form substantially solid flux-conducting structures. Such apparatus may employ multiple ferromagnetic materials to conduct major portions of the magnetic flux in the apparatus magnetic circuit. Apparatus is also described in which magnetic and mechanical support functions reside in differing ferromagnetic or structural plastic materials in composite structures.

Abstract: An apparatus for forming a stack of interlocked laminations (disks) that can be used as a rotor in an electric motor. Each disk is severed from a metal sheet that is passed horizontally through a die apparatus. The severed disks are sequentially driven downwardly into a vertical die opening having an upper diameter chosen to grip the disk edges, as a stack is being formed. The lower end of the stack advances into an expandable rotatable collet. When the stack has passed below the upper end of the die opening, the collet is opened to drop the completed stack to a conveyor.A sensor device detects the lowest disk in the descending stack. A signal generated by the sensor device is used to determine the number of disks necessary to finish the stack by dividing the unfinished height of the stack by the thickness of the advancing metal sheet.

Abstract: A method and apparatus for manufacturing laminated assemblies having ridges formed on projections which interlock with recesses of adjacent laminations. The improvement to the laminated assembly is a projection with a smaller cross-sectional area than the recess and with a plurality of exterior longitudinal ridges protruding from the projection surface for securing adjacent laminations together by compressive interference fit between the ridges and the recess in interlocking relationship throughout the laminated assembly. An improvement in the method for the manufacture of a pack of metal laminae by use of a multistation progressive die operation on a strip of material, during the step of punching the recesses and simultaneously forming interlocking projections in a lower die, the improvement being forming the projection with a smaller cross-sectional area than the recess and with a plurality of exterior longitudinal ridges protruding from the projection surface for securing adjacent laminations together by compressive interference fit between the ridges and the wall of the recess. The projection is formed in a lower die of the multistation progressive die apparatus, wherein the lower die has a plurality of longitudinal grooves on the interior surface of the lower die to produce the ridges protruding from the circumferential surface of the projection simultaneously as the punch produces the recess in the upper portion of the plate.
