Overview

ABL1000 series stages are the highest performance miniature air-bearing stages available. Aerotech has combined industry-leading motion control and positioning system experience with the latest technologies to produce a truly outstanding miniature, linear air-bearing stage.

Linear Stage

The linear positioner is a fully preloaded, noncontact design. Inherently frictionless, air bearings have proven to be the standard in precision applications. Driven by a noncontact linear brushless servomotor, this stage proves the ultimate solution whether the application requires small, accurate steps or constant smooth velocity. Superior magnetic field and motor coil design result in the highest force output of any miniature air-bearing stage. This stage offers superior servo performance and features a robust and perturbation-free cable management system.

Feedback and Control System

A wide selection of state-of-the-art controllers are available along with a variety of high-performance linear and PWM amplifiers.

Options

Convenient rack or panel-mount amplifiers are offered with all systems. Aerotech’s expert technical staff is experienced in custom system designs and will work with you to generate a system to meet the unique needs of your application.
