Abstract

The invention relates to an economical, non-wearing, electrical permanent magnet drive for actively controlling the rotor position in three degree of freedom. The stator windings produce superimposed fields with different pole numbers in the pole pitches by unsymmetrical magnetomotive force distributions.
