Aerotech’s new AMG LP (Low Profile) 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 LP series is ideal for
directing optics, lasers, antennas, and sensors at high speed
to precise pointing angles. Typical applications include
missile seeker test and calibration, electro-optical sensor
and FLIR testing, optical testing of sensors in a vacuum,
and angular testing of inertial sensors such as gyros,
MEMS, and accelerometers. The AMG LP 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.

Low Profile
By incorporating our low profile direct-drive rotary stages,
the LP series is capable of speeds and accelerations that are
significantly higher than other competing products of this
size. These gimbals have a lower profile compared to
competing products within given torque ranges. This results
in a smaller and more effective gimbal for many
applications where beam height and chamber volume are of
utmost concern. Customers with only limited azimuth travel

requirements can have the slip-ring removed for an even
lower overall height. Keeping the optical path lower helps
improve overall test accuracy. Based on the ADRS rotary
stage, the AMG LP provides a high accuracy, smooth
motion solution with low maintenance and high reliability.

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 0.87 to 0.32
µrad with Aerotech controls. Built-in azimuth slip ring
provides for continuous rotation with no cable wrap up.

Superior Mechanical Design Features
High-quality, low-profile bearings maximize performance
with respect to wobble, moment stiffness, and rotating
friction. Travel limits and hardstops, and brakes are
available as standard options.
