ABSTRACT:
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.
