Abstract
In a rotor of an electric machine, which rotor consists of individual segments which each have a first part which is in contact with a second cooperating part wherein the first part of an individual segment and the second cooperating part of an adjacent individual segment are positively interlocked in the radial and circumferential directions resulting in a self-supporting annular structure of the assembled rotor. The individual sections have openings accommodating permanent magnets which are fixed in the openings by wall sections bent into the openings during assembly of the segments for fixing the permanent magnets in the openings as the individual segments are joined to form a ring.
