  • Patent number: 12272493
    Abstract: A method for producing a spiral-shaped body, in particular an electric coil, made of an electrically conductive material. First, the material is wound about a mandrel in a casting mold in order to form a coil with a plurality of windings, and pressure is then exerted onto the coil in the axial direction of the coil. The pressure leads to a deformation and compression of the cross-section of the individual windings in the axial direction of the coil. By compressing the coil, an optimal use of space is achieved with an electric coil, for example for an electric machine.
