Abstract (en)

[origin: WO2008147189A1] An actuator (1) has an annular magnet (3) displaceable in axial direction, with attached thereto on either one of the two sides annular, displaceable flux conductors (5). The actuator (1) further has two annular coils (7) surrounding the magnet at a distance with a gap (9) therebetween, and an annular, static flux conductor (11) surrounding the coils, which is in contact with the outside of the coils. The gap (9) accommodates an additional annular, static, ferritic flux conductor (13) whose outside surface is attached to the inside surface of the static flux conductor (11). The static flux conductor (11) is laminated with the layers resting on each other in radial direction.
