Features of the ABRS series rotary air-bearing stages include direct-drive slotless, brushless servomotor; zero cogging motor for velocity stability; low-profile, planar design; and no mechanical contact. An optical encoder is standard with the ABRS. When coupled with the company's feedback multipliers and controls, resolutions of <0.03 arc sec are achievable. Custom versions of the ABRS are available for rate table and inertial guidance test-stand applications. Aerotech Pittsburgh, PA, USA www.aerotech.com
