  • Patent number: 9620271
    Abstract: An actuator has an electrically conductive coil which has a longitudinal axis and a plurality of turns and a magnet arranged at a distance from the turns in radial direction relative to the longitudinal axis. The coil is partially covered by a central region of a first conducting element on a side which faces away from the magnet and the magnet is partially covered by a mid region of a second conducting element on a side facing away from the turns of the coil. The first conducting element projects beyond the coil and the second conducting element projects beyond the magnet in the direction of the longitudinal axis and there each have collar-like projections. The coil has a first winding turns region and a second winding turns region.
