Abstract
An electromagnetic device comprises an annular armature an inner stator structure defining outwardly extending pole pieces and an outer stator structure defining inwardly extending pole pieces, the armature being of generally tapering form. The stator structures each carry windings whereby when the winding on the outer stator structure is energized the armature will move in one direction and when the winding on the inner stator structure is energized the armature will move in the other direction. The stator structures are so disposed that the magnetic circuits in the armature for the flux produced by the inner and outer stator structures when the respective windings are energized, are displaced relative to each other.
