Abstract: A coil arrangement has at least four coil cores around which in each case a coil winding is disposed, wherein the coil cores project over the coil windings in each case with a first coil core end region and a second coil core end region, wherein the coil arrangement furthermore has a first yoke part and a second yoke part. The first and second coil core end regions of the first and second coil core are in each case disposed opposite a first yoke side face of the first or second yoke part respectively, and the first and second coil core end regions of the first and second coil core are in each case disposed opposite a second yoke side face of the first or second yoke part respectively.

Abstract: A method for the mechanical winding of a coil having at least one wire is disclosed. The coil has a coil inner side and at least two winding layers, with one winding layer being formed by turns situated essentially parallel to the coil inner side, to increase the precision of the winding and to reduce the dimensional tolerances of the winding. At least during the winding of a first winding layer, a gap is formed at a predefinable position between a first turn and a second turn adjacent to the first turn, with the second turn being wound immediately following the first turn. The width of the gap at least regionally is at least one wire diameter, and the wire is guided into the gap after the winding of the second turn, and optionally after the winding of further turns, thereby forming at least one support turn.
