Abstract

A bearing arrangement (100) for a spinning rotor shaft (200) of an open-end spinning device, a spinning rotor shaft (200) for such a bearing arrangement (100) and a spinning rotor drive device comprising such a bearing arrangement (100) and such a spinning rotor shaft (200). The bearing arrangement (100) comprises at least one active magnetic radial bearing (110) for the spinning rotor shaft (200) which can be influenced by means of an electronic control system (300). The bearing arrangement is characterized in that the bearing arrangement (100) comprises an active magnetic axial bearing (130) for the spinning rotor shaft (200) which can be influenced by means of the or another electronic control system (300).
