摘要：In prior art three-phase electric machines with a layered winding, the conductorelements either make non-optimal use of the space in the groove or the conductors foreach phase are in the form of large elements designed to be fitted into each other andwhose manufacture is complicated and costly. The invention calls for the conductor lanes(5- 7) for each phase in the three-phase conductor layer (11) to be identical in

construction and for the construction to be repeated every four pole pitches. While theconductor lanes (5-7) occupy the full height of the layer within the magnetic field, twoconductor lanes (5-7) stacked in the groove share the space at the winding ends (19). Atthe groove exit, the conductor cross-section increases and only later, at the winding end(19) is bisected from only one side at each passage through the winding end. In order toalternate the halves of the layer, contact surfaces are available which are large incomparison to the conductor cross-section and the two winding ends (19) are uniformlyutilized due to the interlacing of the lanes. The production of three- phase conductorlayers by alternating application of conducting and insulating layers is particularlysuitable for small electromagnetic machines, resulting in uniform space utilization andhence high effectiveness and a high power density at low cost, and requiring only a few

operations.
