Abstract

The rotor (4) has a section (41) and another section (42) that follow each other in an axial direction. Each of the sections is arranged with permanent magnets, and flux concentration, where the magnets are angularly shifted with regard to each other around an axis of rotation. An intermediate disk (43) composed of a non-magnetic material is located between the former section and the latter section, and the angular shift of the former section and the latter section lies between 1 and 100. An independent claim is also included for a revolving electric machine.
