Abstract: An electromagnetic rotary drive includes a ring-shaped magnetically effective core arranged around a stator and has a magnetic central plane. The stator is a bearing and a drive stator, with which, the rotor is contactlessly magnetically drivable about an axis of rotation, and with which the rotor is contactlessly magnetically levitatable with respect to the stator. The rotor actively magnetically levitated in a radial plane perpendicular to an axial direction, and passively magnetically stabilized in the axial direction and against tilting. The rotor includes a magnetically effective bearing ring arranged radially externally disposed and spaced from the magnetically effective core, and a bearing stator having a magnetically effective stator ring interacts with the bearing ring. The bearing stator is configured such that the stator ring passively magnetically stabilizes the rotor against tilting, and the bearing ring is connected to the magnetically effective core of the rotor via a connecting element.

Abstract: An electromagnetic rotary drive includes a rotor including a magnetically effective core surrounded by a stator. The stator has poles arranged around the magnetically effective core and each of the poles is delimited by an end face. The rotor is capable of being magnetically driven without contact in an operating state about an axial direction, and is capable of being magnetically levitated without contact with respect to the stator. The rotor is configured to be magnetically levitated in a radial plane and is passively magnetically stabilized in the axial direction against tilting. The magnetically effective core has a rotor height which is a maximum extension of the magnetically effective core in the axial direction, the rotor height being greater than a stator pole height defined by a maximum extension of the end faces in the axial direction.

Abstract: A viscometer for inline determination of the viscosity of a fluid includes a drive device and a measuring device including a housing and a chamber. The drive device includes a housing in which a stator is arranged. The stator has and having a plurality of coil cores delimited by an end face, and carrying a concentrated winding, and being a bearing and drive stator with which the rotor is magnetically driven without contact and magnetically levitated without contact with respect to the stator. A control device actuates the stator and determines the viscosity based on an operating parameter of the electromagnetic rotary drive.
