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.
