Abstract
A laminated core comprising a plurality of lamination sheets made of a soft magnetic alloy is provided. The lamination sheets have a main surface and a thickness d. The main surfaces of the lamination sheets are stacked one on top of another in a direction of stacking. Adjacent lamination sheets are joined to one another by a plurality of substance-to-substance joints, the joints being filler-free and entirely surrounded by the main surfaces of the adjacent lamination sheets.
