Abstract
The invention relates to a particularly redundant electrical machine () for driving a means of propulsion () with increased reliability. The machine () comprises a plurality of independent partial rotors () which are respectively coupled to a common shaft () by means of freewheel devices () in order to drive said shaft and the means of propulsion () therewith in a working direction of rotation. The machine () also comprises a plurality of independent stator winding systems (), a stator winding system () and a partial rotor () being respectively associated with each other and arranged in such a way that they can electromagnetically interact with each other. The stator winding systems () are successively arranged in the axial direction. Similarly, the partial rotors () are successively arranged in the axial direction.
