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).
A bearing arrangement for a spinning rotor shaft of an open-end spinning device, wherein the bearing arrangement comprises at least one active magnetic radial bearing for the spinning rotor shaft which can be influenced by an electronic control system, characterized in that the bearing arrangement comprises an active magnetic axial bearing for the spinning rotor shaft which can be influenced by the or another electronic control system, wherein the active magnetic axial bearing is arranged to be positioned opposite a casing surface section of the spinning rotor shaft to be supported, which casing surface section is step-like in cross-section.
A spinning rotor shaft for the active magnetic support of a bearing arrangement, characterized in that the bearing arrangement comprises at least one active magnetic radial bearing for the spinning rotor shaft which can be influenced by means of an electronic control system, wherein the bearing arrangement comprises an active magnetic axial bearing for the spinning rotor shaft which can be influenced by means of the or another electronic control system and the active magnetic axial bearing is arranged to be positioned opposite a casing surface section of the spinning rotor shaft to be supported, which casing surface section is step-like in cross-section, and the spinning rotor shaft is made from a magnetic flux conducting material at least in some shaft sections, through which in the supported state electromagnetic fluxes flow for the axial and radial bearing of the spinning rotor shaft.
A spinning rotor drive device for an open-end spinning device comprising a drive housing with a bearing arrangement comprising at least one active magnetic radial bearing for the spinning rotor shaft which can be influenced by means of an electronic control system, wherein the bearing arrangement comprises an active magnetic axial bearing for the spinning rotor shaft which can be influenced by means of the or another electronic control system and the active magnetic axial bearing is arranged to be positioned opposite a casing surface section of the spinning rotor shaft to be supported, which casing surface section is step-like in cross-section, the bearing arrangement in connection with a corresponding spinning rotor shaft made from a magnetic flux conducting material at least in some shaft sections, through which in the supported state electromagnetic fluxes flow for the axial and radial bearing of the spinning rotor shaft.
