AGR series motorized rotary stages provide significant
improvements in speed, load capacity, and long-term
positioning performance over previous generations of
worm-gear-drive stages. AGR series stages address a wide
range of applications for general purpose positioning in
laboratory and industrial uses.
Construction Features
The addition of a larger clear aperture is a key enhancement
over previous generations of worm-gear-driven stages. This
feature allows the AGR series to address applications
requiring a through-hole or accommodations to mount an
optic, including articulation of beam polarizing lenses,
through-holes for cabling and/or air lines, or
vision/camera/inspection applications.
The AGR stage base is fabricated from a special aluminum
alloy which offers significant weight savings in multi-axis
arrangements and other weight critical applications, while
providing high structural stiffness and long-term stability.
Each stage incorporates dual large diameter pre-loaded
angular contact bearings optimally separated to provide
excellent error motion specifications, as well as best
possible load handling capability.
All stage tabletops feature aluminum hardcoat plating and
stainless-steel Heli-Coil®; inserts to prevent thread wear.
Flexible Options
Options include flexible motor selections as well as a direct
encoder mounted concentric to the axis of rotation for
outstanding repeatability and to virtually eliminate
hysteresis and backlash. Vacuum-compatible versions (for
use in pressures as low as 10-6 torr) are also available.
Motor and Drives
Standard AGR stage configurations feature Aerotech’s
brushless servomotors. However, all AGR stages can be
outfitted with stepper or DC brush motors. A full range of
matching drives and controls are available for a complete
single-source solution.
