Abstract:
1. An actuator comprising: an electrically conductive coil defining a longitudinal axis (L) and having a plurality of winding turns; a magnet spaced from said winding turns in radial direction with reference to said longitudinal axis (L); said coil having a side facing away from said magnet; a first conductive element having a mid region at least partially covering said coil on said side facing away from said magnet; said magnet having a side facing away from said winding turns of said coil; a second conductive element having a mid region at least partially covering said magnet on said side thereof facing away from said winding turns of said coil; said first conductive element projecting beyond said coil in axial direction with reference to said longitudinal axis (L); said second conductive element projecting beyond said magnet in axial direction with reference to said longitudinal axis (L); said first and second conductive elements having respective collar-shaped projections whereat said first and second conductive elements project beyond said coil and said magnet, respectively; and, at least one of said first and second conductive elements being made of soft-magnetic powder composite material.
