Abstract
An electromagnetic rotary drive includes a magnetically contactlessly drivable rotor free of coils, and a stator configured as a bearing and drive stator configured to drive the rotor magnetically and contactlessly about an axis of rotation. The rotor is capable of being supported magnetically contactlessly with respect to the stator in an operating state. The stator includes an upper stator part having a plurality of pronounced upper poles configured to carry upper windings and a lower stator part having a plurality of pronounced lower poles configured to carry lower windings. The upper stator part and the lower stator part are arranged spaced apart from one another with respect to an axial direction. A permanent magnet is disposed between the upper stator part and the lower stator part.
