Abstract (en)

The winding has a wire wound around a carrier body (43), like a screw. The carrier body has spacer grooves, into which the turns of the wire fit. The carrier body has a rectangular, preferably square cross-section, whose long edges have indentations to act as the spacer grooves. The coil forms a cylindrical surface, whose diameter corresponds to the inner surface of the indentations.
