Abstract

A simplified magnetic reluctance coupling for coupling a first shaft to a second shaft, has a hollow cylindrical stator which has at least one magnet that is/are distributed around the circumference of the stator. The reluctance coupling also has a first rotor, which is supported in such a way that it can rotate within the stator, is connected to a first shaft in a rotationally fixed manner, and has a plurality of ferromagnetic first portions distributed around the circumference thereof and spatially separated from one another, as well as a second rotor, which is supported in such a way that it can rotate within the first rotor, is connected to the second shaft in a rotationally fixed manner, and has a plurality of ferromagnetic second portions distributed around the circumference thereof.
