asrt rotaryASRT 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.

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.
