An electromagnetic driving device which includes two parts which are movable relative to one another, each part supporting a plurality of magnetic poles which act together with the magnetic poles of the other respective part to produce a force causing a relative movement of the parts. The poles of at least one part are designed as electromagnetic poles whose magnetic polarization is controlled. The poles of at least one part are arranged in at least three groups extending in the direction of relative movement and the pole spacings within each group, measured in the direction of relative movement, being constant and of equal magnitude in all groups. The poles of the other respective part which cooperate with the poles disposed in groups are arranged in at least one grouping which extends at an angle to the direction of relative movement and which traverses the entire width covered by the pole groups of said first part. |
