Abstract
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.

A magnetically journalled rotational arrangement comprising a substantially disc-shaped or ring-shaped magnetically journalled rotor and
- a stator comprising:
- means for generating a field, wherein said field produces rotation of the rotor having means for generating a unipolar bias magnetic flux spatially modulated when viewed in the circumferential direction;
- and
- a plurality of permanent magnets arranged to cooperate with the means provided on the rotor generating the spatially modulated bias magnetic flux and producing or reinforcing the magnetic journalling of the rotor,
