Abstract
The invention relates to a rotor arrangement (4) for an electric machine (1), comprising: - a permanent magnet (7); and - at least two pole shoes (42), between which the permanent magnet (7) is arranged, with the result that the magnetization direction of said permanent magnet in a first section (71) of the permanent magnet (7) is aligned substantially in the direction of arrangement of the pole shoes (42); wherein, in a second section (72) of the permanent magnet (7), the magnetization direction deviates from the direction of arrangement.
