Coil and method and tool for producing coil

A method for producing a coil, the method comprising:

• casting a semi-finished product in a form of a single elongate conductor in a cavity of a casting tool, wherein the coil is formed following demolding of the semi-finished product by reshaping the semi-finished product;
• wherein the form of the semi-finished product is derived from a shape of the coil by at least one of stretching along a longitudinal axis of the coil and bending the longitudinal axis, wherein the semi-finished product is formed as a rosette, formed by the single elongate conductor, such that windings are arranged fanned out around a center point prior to the reshaping;
• reshaping the semi-finished product, wherein the semi-finished product, during the reshaping, is bent and compressed so that the 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 coil, wherein the elongate conductor, whilst being shaped, is one of twisted and bent by no more than a right angle along each individual winding of the coil.
