Electronic damping apparatus

摘要: Apparatus is disclosed for controlling the movement of a movable element to bring rest at desired stopping position. The apparatus comprises multi-phase drive motor having shaft coupled driving same, four electrically conductive coils mounted in position-displaced relationship about shaft, and means responsive selective energization by respective signals causing corresponding rotation said element. A sensor thereof generating an electrical signal containing information indicative direction, speed distance Further, are included detecting from indicated whether within predetermined When it is, controller controls levels dependence upon direction such that thus brought final stop with only single one coil on. selectively turns on off or reverses either two displaced counterclockwise clockwise signal.
