FIELD: electricity.SUBSTANCE: electromechanical drive for detecting head of bitmap image element contains electromagnetic stator fixed at the base and magnet core with two poles and single-phase winding, rotor movable at rotation axis and mechanism for rotor fixation with permanent magnet. The base has jacks for installation of stator magnet core that provides accurate positioning of rotor core in regard to stator magnet system by special thrusts, supports for rotor installation; rotor has a body and multi-tooth closed magnet core, one of core poles has a tooth with different geometric properties; mechanism of fixation consists of permanent magnet fixed at stator and multi-pole magnet core installed at rotor with angle pitch equal to rotor pitch. Invention is referred to electromechanical display containing walls, base with rotor holders and jacks for installation of stator cores and magnets and at least one electromechanical drive.EFFECT: creating electromechanical drive with possibility to form depth of display image and to transfer colour shades; creating drive with improved reliability of performance of turn command and decreased probability of errors at image displaying.6 cl, 15 dwg |
