Abstract: In a method an inner segment is first pre-assembled on each of a number of outer segments by at least one fixing element, so as to produce a plurality of segment modules having each a predetermined air gap between the inner segment and the outer segment. The inner segments and the outer segments are assigned to the rotor or stator of the electrical machine. The inner segments of the plurality of segment modules are fastened to an inner assembly device (for example a hub). The outer segments of the plurality of segment modules are fastened to an outer assembly device (for example a supporting structure). Finally, the fixing elements between the inner segments and the outer segments are removed.

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.
