Aerotech’s AMG position and rate gimbal mounts provide
ultra-precise angular position, rate, and acceleration for
development and production testing of a wide range of
systems. The AMG series is ideal for directing optics,
lasers, antennas, and sensors at high speed to very precise
pointing angles. Typical applications include missile seeker
test and calibration, LIDAR, electro-optical sensor and
FLIR testing, airborne targets tracking, optical testing of
space-based sensors in a vacuum, and angular testing of
inertial sensors such as gyros, MEMS, accelerometers, and
inertial reference units. The AMG gimbal design
incorporates recent Aerotech rotary stage design
improvements to provide high performance at an affordable
price. The finest quality motors, bearings, and encoders are
integrated into precision-machined housings to ensure peak
performance. The AMG position and rate gimbals provide
precise angular motion with the high performance
customers expect from Aerotech products.

Accurate 360° Positioning and Rate Generation
Direct-drive brushless torque motors, with rare-earth
magnets and high-accuracy angular 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
ensure highly accurate and repeatable positioning.
A wide-range of performance feedback grades is available.
Typical line gimbal resolution ranges from 1.0 to 0.13 µrad
with Aerotech controls. The built-in azimuth slip ring
provides for continuous rotation with no cable wrap up.

Direct-Drive Motors for Outstanding Control
To maximize positioning and velocity performance, AMG
gimbal mounts utilize Aerotech’s high torque S-series
brushless, slotless servomotors. These motors have 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. These
motors are available in different winding configurations to
work with high or low voltage power supplies.

Superior Mechanical Design Features
Large diameter, matched-set ABEC-7 bearings maximize
performance with respect to wobble, moment stiffness, and
rotating friction. The large diameter bearing permits large
payload capacity without compromising performance.
