Title:
OBLIQUE DRIVE CONTROLLER
Document Type and Number:
Japanese Patent JPS59132765
Kind Code:
A
Abstract:
PURPOSE:To accurately control the drive of an oblique drive controller by contactlessly operating a movable coil supported by a center suspension spring in a gap of a magnetic circuit device and coupling the coil to an oblique stage by a unidirectional displacement spring. CONSTITUTION:Voice type linear motors 1a, 1b as actuators are disposed symmetrically to the central position of the inclining angle at the center of an oblique stage 3. The positions of movable coils 5a, 5b in a magnetic gap are displaced by controlling currents of the coils 5a, 5b of the motors 1a, 1b, and the inclining angle of the stage 3 coupled to unidirectional displacement springs 9a, 9b is controlled by movable coils 6a, 6b. Gap sensors 10a, 10b respectively measure the gaps between the ends and the stage 3, feed back the outputs to a current controller of the coils 6a, 6b, thereby accurately controlling the inclining angle of the stage 3.
