Abstract
A magnetically journalled rotational arrangement comprises a bearing stator and a rotor, with the bearing stator being magnetically coupled to the rotor and producing a magnetic journalling of the rotor. The bearing stator is rotatably journalled. Furthermore, a rotary drive which is associated with the bearing stator is provided, with a rotation of the bearing stator producing a rotation of the rotor via the magnetic coupling of the stator to the rotor.
