MI-8100 Family of Precision Two-Axis Gimbal Positioners

MI-8100

Incorporating direct drive motors and extremely accurate encoders, the MI-8100 Gimbals provide superb responsiveness and pointing accuracy. The MI-8120 Two-Axis Gimbal offers extreme accuracy by virtue of its direct drive motors that are structurally coupled to the encoders and the antenna/ counterweight system. Flexible couplings are absent, as are gears, timing belts and virtually all the conventional sources of positioning error in a mechanical drive. System stiffness is thereby greatly enhanced, and backlash is completely eliminated.
