AMG gimbal design incorporates direct-drive brushless torque motors, with rare-earth magnets and high-accuracy angular transducers coupled directly to precision shafts for accurate and smooth 360° continuous motion. The absence of gear trains and other drive mechanisms eliminates position error due to mechanical hysteresis and backlash. Typical line gimbal resolution ranges from 1.0 to 0.13 μrad. The built-in azimuth slip ring provides continuous rotation with no cable wrapup. A variety of mirror-cell diameters is available for standard optic applications. Each gimbal mirror cell can be modified or replaced with different shaped cells to accommodate sensors or other odd shaped payloads.
