[0062] The wall 5 is arranged between the main permanent magnet and the peripheral permanent magnets and is cylindrical. An electrical conductor 17 is wound in the form of a coil 18 around the wall such that rotation of the main permanent magnet induces an electric current in the electrical conductor.

The wall 5 is cylindrical and an electrical conductor 17 is wound around it in the form of a coil 18. FIG. 2 shows electrical generators 8 which are arranged distributed along the main axis of rotation 3 and the circumferential direction, in particular and fastened to the wall 5, in such a manner that rotation of the main permanent magnet, by means of the rotary drive, causes rotation of the peripheral permanent magnets 6 about respective peripheral axes of rotation 7 and, as a result, rotation of the drive shafts 9 of the electrical generators. The electrical generators are arranged in such a manner that the peripheral axes of rotation 7 are each arranged primarily parallel to the main axis of rotation 3. The peripheral permanent magnets are each coupled by respective disk-shaped drive elements 16 to a respective rotatable drive shaft of a respective electrical generator.

The rotary drive shown in FIG. 3 has propeller-shaped rotary drive elements 19 which are connected to the rotary drive shaft for rotation therewith. The wall 5 is conical and forms a conical flow space 13. The flow space is constricted radially in a direction along the rotary drive shaft.
