The AOM360D series positioning gimbal mounts are ideal for automatic testing of components that must be precisely positioned in azimuth and elevation, such as sensors and optics. Other applications include calibration, laser beam steering, target acquisition and tracking, camera and telescope scanning and pointing.
Direct-drive brushless torque motors, incorporating rare-earth magnets and high-accuracy transducers, are coupled directly to precision shafts for accurate and smooth 360° continuous motion. The absence of gear trains and other drive mechanisms eliminates position error contributions due to mechanical hysteresis and backlash. Directly-coupled high-resolution inductosyn position transducers ensure highly accurate and repeatable positioning with gimbal accuracy down to ±5µrad (±1arc sec).
Large diameter, matched-set ABEC-7 bearings maximise performance with respect to wobble, moment stiffness and rotating friction. A thick-walled, precision-ground shaft further minimises wobble. The large diameter bearing permits large payloads without compromising performance. Three tapped holes with levelling screws provide a convenient means to align the gimbal axes with the optical axis.
To maximise positioning performance, AOM360D optical mounts utilise Aerotech’s S-series brushless, slotless servomotors. This motor has all of the advantages of a brushless direct-drive motor – no brushes to wear, no gear trains to maintain and high acceleration and high speeds. Since it is a slotless, ironless design, there is zero cogging, meaning that there is absolutely no torque ripple. This results in smoother motion throughout travel and more precise positioning.
Design Features of the AOM360D Gimbals and Optic Mounts Include:
Continuous 360 degree rotation of both axes
High axis positioning accuracy and repeatability
Low axis wobble and orthogonality
Direct-drive brushless servomotors
High accuracy induction feedback
Cog-free design for outstanding velocity stability
Accommodates loads up to 500mm diameter
Vacuum-compatible versions available
