Abstract: The plane torsion spring has an inner fastening point, at least two outer fastening points, and at least two spring arms. Each of the at least two spring arms connects the inner fastening point to one of the outer fastening points in a spring-elastic manner. The spring arms have a similar contour and extend symmetrically, preferably point-symmetrically, with respect to the inner fastening point. The spring arms of the plane torsion spring have an S-shaped profile.

Abstract: An additively manufactured air gap winding for an electrical machine is provided. The air-gap winding includes a hollow cylindrical main portion having a geometric axis, the main portion defining an active winding length of the winding, and electrical winding conductors of the winding extending in the main portion from a first axial end of the winding to a second axial end. The air gap winding further comprises a first winding head at the first axial end and a second winding head at the second axial end, wherein winding head connections of the winding conductors extend in the winding heads. The winding heads project radially inwardly and/or outwardly beyond the hollow cylindrical main section. The winding head connections extend at least in sections at different distances from the axis in such a way that one winding head connection at least partially radially surrounds the other winding head connection.
