ARMS Series
Rotary Motion Simulators
Designed for highly accurate motion generation
Velocity stability of 0.0001% over 360°
Position resolution to 0.02 arc sec
Payloads to 230 kg
Integrated slip rings and fluid rotary unions
Direct-drive brushless motor options for high
speed or high torque
Aerotech’s ARMS series direct-drive rotary motion
simulators provide superior angular rates, accelerations, and
positioning for the testing of inertial components and
systems such as MEMS, gyroscopes, inertial measurement
units, avionics, and accelerometers.
produces absolutely no torque ripple. With its low inherent
inertia and optimized motor design, the ARMS is capable
of speeds and accelerations that are significantly higher
than competing products. Low inertia and zero backlash
make the ARMS the ideal solution for applications
requiring frequent directional changes.
Accurate Velocity and Positioning
The ARMS family of stages provides excellent velocity and
positioning control. When coupled with Aerotech’s
advanced controls, resolution can be as fine as 0.02 arc
second, with accuracy to ±2.5 arc second and repeatability
to ±0.5 arc second. The motor and high-performance rotary
encoder are directly coupled to a common shaft. The
absence of gear trains and mechanical couplings means no
position errors caused by hysteresis, windup, or backlash.
The ARMS has rate resolution down to 0.002 deg/s and rate
stability to 0.0001%.
Superior Mechanical Design
Dual large-diameter bearings are used to maximize
performance with respect to wobble, moment stiffness, and
repeatability. The large diameter bearings permit large
payloads without compromising performance.
Brushless Direct-Drive
The ARMS series utilizes Aerotech’s S-series brushless,
slotless motor to maximize positioning performance. The Sseries motor provides 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. The
slotless, ironless design eliminates cogging and, therefore,

Flexible Configurations
Slip rings and rotary unions are standard options available
to ease integration of customer devices. With various
tabletop styles as well as optional HDP pedestals,
customers can also tailor the mechanical interface of the
ARMS stages to suit many different needs.
Advanced User-Friendly Controls
Aerotech rate tables are controlled with state-of-the-art
Aerotech controls and drives. Our software packages are
available as stand-alone applications, where no other
language or compiler is needed, as well as LabVIEW®, C,
and .NET software interfaces. Users can graphically
generate their own motion profiles and execute them
automatically with Aerotech’s new GUI Motion Designer
software. Or, for users who already have their own motion
simulation software, our software can easily accept files
with arrays of velocity, position, and acceleration versus
time profiles. This is then downloaded and run on the
ARMS by our motion control software.
