  • Drive with voice coil motor
    Publication number: 20090097164
    Abstract: A drive is provided executing high-speed oscillatory motion. A voice coil motor in a pixel shifter includes a coil of a rectangular shape producing thrust along an axis, a flap fixing the coil, and flat springs giving to the flap an urging force against the thrust. An oscillation axis of the flap is parallel to the axis and located between another axis that is parallel and opposite to the axis and still another axis that is parallel to the axis and passes over a centroid of the coil. This reduces the value of the inertia per unit torque.

  • Voice Coil Motor
    Publication number: 20090073614
    Abstract: A voice coil motor has an arm for arcuate movement about a pivot, and a coil at one end of the arm. There is a permanent magnet mounted adjacent the coil. The permanent magnet has only one pole facing, and for operational co-operation with, the coil. The coil has a centre of mass and a geometric centre. The center of mass and the geometric centre are coincident. The coil is mounted to the arm perpendicular to a movement plane of the arm for the arcuate movement.
