Abstract: An active part of an electrical machine has a carrier, a plurality of coils which are arranged on the carrier and which each include a plurality of sub-conductors and a winding head area, in which the coils project out of the carrier in a curved shape, respectively and are connected to one another. At least one of the plurality of coils has a coil arc in the winding head area, and the center line of the coil runs in one plane in the coil arc. The sub-conductors of one coil run parallel to the plane in the coil arc of the coil and themselves in each case form sub-conductor arcs. The vertices of the sub-conductor arcs of the coil form a line of inclination which runs at an angle to the plane.
