SPINNING ROTOR SHAFT, BEARING ASSEMBLY FOR ACTIVE MAGNETIC BEARINGS OF SUCH A SPINNING ROTOR SHAFT AND SPINNING ROTOR DRIVE

摘要

The invention relates to 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) has an active magnetic axial bearing (130) for the spinning rotor shaft (200) which can be influenced by means of the or a further electronic control system (300).
