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.
The presence of a large, clear aperture in the stage 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 an aluminum alloy that offers significant weight savings in multi-axis arrangements and other weight critical applications, while providing high structural stiffness and long-term stability.
Each stage is designed with two high-precision angular contact bearings with optimal spacing to provide excellent error motions coupled with high load capacities in a small, compact package.
Options include flexible motor selections as well as a direct encoder mounted to the stage shaft 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.
