Abstract

A bearing system and associated method of operation are provided to support a spinning rotor having a pot and a shaft of an open-end spinning device with two radial bearings and at least one axial support bearing, wherein at least one of the radial bearings is an active magnetic bearing. The axial support bearing is configured such that a magnetic bearing acts in opposition to one or both of an aerostatic air bearing or a mechanical starting element.
