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.
