Claim 0:
1. An electromagnetic rotary drive configured as a temple motor, comprising:
a rotor comprising a ring-shaped or disk-shaped magnetically effective core; and
a stator configured as a bearing and drive stator, by which the rotor is configured to be magnetically driven without contact in an operating state about an axis of rotation which defines an axial direction, and by which the rotor is capable of being magnetically levitated without contact with respect to the stator, the rotor configured to be actively magnetically levitated in a radial plane perpendicular to the axial direction and passively magnetically stabilized in the axial direction and against tilting, the stator having a plurality of coil cores, each of the coil cores comprising a longitudinal limb extending in the axial direction and a transverse limb arranged in the radial plane, the transverse limb extending from the longitudinal limb in a radial direction and bounded by an end face facing the magnetically effective core of the rotor, and at least one concentrated winding arranged on each of the longitudinal limbs surrounding a respective longitudinal limb, each of the longitudinal limbs comprising a first portion and a second portion arranged adjacent to each other with respect to the axial direction, the transverse limb for each of the coil cores arranged at the second portion, the end face of each of the transverse limbs has a first distance in the radial direction from the first portion of the respective longitudinal limb and a second distance in the radial direction from the second portion, the second distance greater than the first distance.
