Abstract
A method for producing a coil includes casting; a semi-finished product in a cavity of a casting tool and the coil is formed following a demolding of the semi-finished product by shaping this semi-finished product, wherein the form of the semi-finished product may be derived from a shape of the finished coil by stretching along a longitudinal axis of the coil and/or by bending this longitudinal axis, and wherein the semi-finished product, during the shaping, is bent and compressed so that windings of the coil already present in the semi-finished product are brought closer to one another at least in some regions and are brought into an arrangement along the longitudinal axis of the finished coil, wherein the product, whilst being shaped, is twisted or bent by no more than a right angle over the course of each individual turn.
