        Design Feature

         
        A. Direct-drive linear motor positioning system
        B. Precise motion and homing
        C. Great mechanical stiffness
        D. H drive design
        E. H drive with dual feedback/ H drive with single feedback
         
        GHD Stage (Gantry H Drive Stage), driven by Akribis' linear motor system, is with great positioning accuracy and great mechanical stiffness. Two solutions are available, H drive with dual feedback and H drive with single feedback. H drive with dual feedback is suitable for long-length bridge or high level accuracy condition. H drive with single feedback is suitable for short-length bridge or reasoable lower level accuracy condition.
