Known turn-to-turn windings with overlapping, sinuous conductor strands either only insufficiently use the slot space or are difficult to produce. In addition, no uniform distribution of the current intensity is achieved in the winding head space. The disclosed multiple-phase conductor layers are made of identical conductor strands located in the slot space at the same distance from the air gap surface. The conductor layers superimposed in the slots supplement each other in the use of the winding head space in that they lead the current in opposite directions across the width of the slot. A uniform distribution of the current intensity and a high space utilisation are achieved in that the layered winding heads are offset relative to the layers in the slot in the direction of the slot depth by half the height of a layer. Each conductor strand occupies two winding head layers when crossing the winding heads, the layers being exchanged at about the centre of the connection section at the outside of the winding heads. Alternating second conductor layers in succession are directly interconnected. Engines and generators equipped with space-optimised turn-to-turn windings are characterised by a high effectiveness and power density.
