ABSTRACT:
Iron core for an electric machine such as a transformer, a choke, a voltage stabilizer and the like, assemblable of a plurality of individual parallelepipedal core parts formed of laminated layers mutually held together, the core parts having mutually abutting joints formed with smoothly finished surfaces free of any metallic connection between the individual layers, includes clamping means applicable to a clamping surface at outer contours of the core and extending transversely to the laminated layers, clamping elements for clamping the clamping means so as to hold the individual core parts together, the clamping means includes strap-like members for distributing clamping force at least approximately uniformly to the individual laminated layers between the clamping means and the respective clamping surface.
