AGR series motorized rotary stages from Aerotech, Inc. (Pittsburgh, PA) provide significant improvements in speed, load capacity, and long-term positioning performance over previous generations of worm-gear-drive stages, says the company. They can address a wide range of applications for general purpose positioning in laboratory and industrial uses, in a robust and economical package. Options include brush, brushless, and stepper motor selections as well as a direct encoder mounted to the stage shaft for repeatability and to virtually eliminate hysteresis and backlash. A full range of matching drives and controls are available for a complete single-source solution. Vacuum-compatible versions for use in pressures as low as 10-6 torr are also available.
