Abstract: A stator of a permanently excited rotating electric machine has a plurality of segments abutting each other at radially and axially extending segment boundaries. Each segment has a plurality of radially projecting teeth of uniform width and grooves extending in the axial direction and alternatingly arranged in a peripheral direction of the stator. Abutting segments touch each other at the segment boundaries such that an outer tooth of one segment touches an outer tooth of an abutting segment, wherein a sum of the widths of the two teeth touching each other at the corresponding segment boundary is greater than the uniform width of at least a majority of the plurality of teeth of a segment that are not arranged directly at a segment boundary of that segment. Detent moments and/or oscillating moments occurring in a permanently excited rotating electric machine can thereby reduced.

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.
