Magnetically journalled rotational arrangement including a rotor for generating a unipolar bias magnetic flux

摘要

A magnetically journalled rotational arrangement includes a substantially disc-shaped or ring-shaped rotor and a stator. The stator includes structure for the production of a field which produces a rotation of the rotor. The rotor has structure which produce a unipolar bias magnetization flux which is spatially modulated when viewed in the circumferential direction.
