ASRT sealed rotary stages provide precise angular
positioning in hostile environments where dirt or liquids are
present. The stage can operate in environments with dust or
fluid jets. The ASRT also can be used where cutting fluids
are present. Applications range from industrial machining
automation to precision sensor positioning in hostile
environments. The ASRT is effective for precise rotary
motion in product environmental test and range tracking
applications.
The ASRT has either high accuracy encoder or magnetic
encoder feedback. Unlimited travel is standard and optional
limited travel is available. The ASRT comes in three
different sizes for different load and torque ratings.
A polymer-based paint on the housing and hard-coated
tabletop is standard for corrosion protection. The stage has
optional brown, green, grey, black, and white paint colors.
Standard operating temperature for the ASRT is 0 to 70°C.
Operation below freezing requires the optional air-purge
and dessicant. Air-purged stages can operate from -20 to
70°C.
Rotary speeds of 100 to 200 rpm are available. The ASRT
includes an electrically grounded shaft and housing to
protect against electrical shock and eliminate RF re-radiation,
and housing grounding points are included.
Circular sealed connectors are standard, while options
include desiccant cartridge, air purge option, and mounting
flange accessory.
Superior Mechanical Design
Dual large-diameter bearings are used to maximize
performance with respect to tilt error motion, moment
stiffness, and repeatability. The large diameter bearings
permit large payloads without compromising performance.
Brushless Direct-Drive
To maximize positioning performance, the ASRT series
utilizes Aerotech’s brushless, slotless motor. 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. The low inertia and zero
backlash make the ASRT the ideal solution for applications
requiring frequent directional changes.
Aerotech manufactures a wide range of servo amplifiers
and advanced controllers to provide a complete integrated
package.
