Aerotech's AOM360D series of positioning gimbal mounts provides ultra-precise elevation-over-azimuth positioning. The
finest quality motors, bearings, and transducers are incorporated into precision-machined housings to assure peak performance.

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.

Accurate 360° Positioning
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 assure highly accurate and repeatable positioning with gimbal accuracy down to ±5 µrad (±1 arc sec).

Superior Mechanical Design Features
Large diameter, matched-set ABEC-7 bearings maximize performance with respect to wobble, moment stiffness, and rotating friction. A thick-walled, precision-ground shaft further minimizes wobble. The large diameter bearing permits large payloads without compromising performance. Three tapped holes with leveling screws provide a convenient means to align the gimbal axes with the optical axis.

Mirror and Alternate Payload Accommodation
A variety of mirror cell diameters are available for standard optic applications. We also provide for custom payload attachment solutions to accommodate various device interfaces. Each gimbal mirror cell can be modified or replaced with different shaped cells to accommodate sensors or other odd shaped payloads. We understand customer payloads vary and our engineers have a variety of solutions to implement offset CG payloads.

Direct-Drive Motors for Outstanding Control
To maximize positioning performance, AOM360D optical mounts utilize 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.
