Abstract

The present invention relates to a rotary positioning device () comprising a circular magnetic track () generating a magnetic field across a circular air gap (), at least three forcers (), each including a plurality of coils () at least partly disposed with the circular air gap () and each being operable for generating a levitation force in a levitation direction orthogonal to the circular magnetic track and a drive force in a drive direction along the circular magnetic track, said forcers being arranged at different angular positions along said circular magnetic track, and a controller () for providing currents to said forcers for individually controlling the generation of a levitation force and/or a drive force by said forcers for effecting a rotational movement, and/or a tilting movement and/or a translational movement of said circular magnetic track.
