Method for removing U-shaped winding elements for an electromagnetically excitable core of an electric rotation machine from a setting tool, wherein the U-shaped winding elements are set and are initially located in the setting tool, wherein in one step the winding elements are partially lifted out from the setting tool, so that parts of rod sections of the winding elements are freely accessible from the outside, characterized in that the winding elements are removed from the setting tool by means of a removal device, by gripping the rod sections.

A multiple stator for an electrical machine includes an excitation winding (5) assembled of a plurality of compound coil members (6) each including a main winding element (8, 9) and a shunt winding element (7). All shunt winding elements (13-16) are made in a single winding operation from a continuous insulated wire (46) wound on winding formers (18-21) created by folding perforated parts of a band-shaped support (17) whereby openings matching the cross-section of respective poles result in the band material. The band-shaped support is provided with notches for anchoring the ends of respective winding elements. The support is arched to match the inner wall of a stator and inserted into the housing whereby chain-link shaped main winding elements (8, 9) surround the individual shunt winding elements. The poles are then inserted into the openings of the winding support and secured to the housing.
