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.
