Overview

Superior Design

The ARA1000 utilizes large air-bearing surfaces for high stiffness and load capacity in a low profile design.

Cable management is a snap with integral motor power and feedback connectors. Because the ARA1000 is a self-contained unit, it can be integrated easily into multi-stage stacks. Either a service loop or an integrated Aerotech cable management system (CMS) can be provided for a highly reliable solution.

Brushless Direct-Drive

To maximize positioning performance, the ARA1000 utilizes Aerotech’s S-series brushless, slotless motor. This motor has all of the advantages of a brushless direct-drive motor — no brushes to wear, no gear trains to maintain and high acceleration and high speeds. Since it is a slotless, ironless design, there is zero cogging, meaning that there is absolutely no torque ripple. This makes the ARA1000 ideal for applications requiring outstanding contoured motion or precise incremental steps. Zero backlash makes the ARA1000 the ideal solution for applications requiring frequent directional changes.

Accurate Positioning

Performance is assured with a 150-line-per-degree encoder that results in 0.012 arc sec resolution. The motor and high-performance rotary encoder are directly coupled to a common shaft.

Flexible Configurations

Aerotech manufactures a wide range of servo amplifiers and advanced controllers to provide a complete, integrated package.
