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 360º 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 position transducers assure highly accurate and repeatable positioning.

A wide-range of performance feedback grades are available. Typical line counts range from 3600 to 36000 lines per revolution. When coupled with Aerotech’s MX series resolution multipliers, resolutions can be as fine as 0.036 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.

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.
