PITTSBURGH, March 18, 2013 — Aerotech Inc.’s AGR series motorized rotary stages provide greater speed, load capacity and long-term positioning performance than previous generations of worm-gear-drive stages.
The stages’ accuracy is to 20 arcsec, with 8-arcsec bidirectional repeatability, 30 rpm maximum speed and 360° continuous or optional limited travels. Tilt error motion is 10 arcsec, axial error motion is 5 µm, radial error motion is 10 µm, and maximum axial load is to 425 kg.
Apertures are available from 5- to 20-mm diameter, enabling 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.
Each stage has two high-precision angular contact bearings, with optimal spacing to provide good error motions coupled with high load capacities.
Options include brush, brushless and stepper motor selections as well as a direct encoder mounted to the stage shaft for repeatability and to eliminate hysteresis and backlash. Matching drives and controls are available for a single-source solution. Vacuum-compatible versions for use in pressures as low as 10–6 torr are available.
