Aerotech's ASR1000 series direct-drive rotary stage was designed to meet the demanding needs of high-performance precision machining. The low-inertia motor and high-accuracy encoder make it the ideal combination of speed and accuracy.

Brushless Direct Drive

To maximize positioning performance, the ASR1000 series utilizes Aerotech's brushless series of motors. Optimized for production applications, the brushless direct-drive motor has the advantage of no brushes to wear and no gear trains to maintain. The low-inertia motor enables the ASR1000 to reach speeds and accelerations that were previously unachievable with earlier generation direct-drive devices or worm-driven stages. Designed for applications requiring frequent direction changes, the ASR1000 offers low inertia and zero backlash in a compact package.

Compact Packaging

The design of the ASR1000 series direct-drive rotary stage was optimized to minimize stage weight. The resulting product - with a net overall weight under 5 kg (10 lb) - is significantly lighter than previous offerings. When used to replace an existing rotary stage in a multiple-axis system, an increase in performance can be expected for all positioning stages carrying the rotary stage.

Accurate Positioning

To maximize position and contour accuracy, the ASR1000 utilizes a high-resolution shaft-mounted rotary encoder. When coupled with Aerotech's MX series multipliers, final resolutions can be as fine as 0.63 arc sec. The absence of gear trains and mechanical couplings means no position errors caused by hysteresis, windup, or backlash. Absolute repeatabilities of ±3 arc-seconds are attainable.
The result is a production-worthy tool that offers higher throughput, lower maintenance, superior final parts, and an outstanding return on investment.

Flexible Options

A large aperture aids high-volume production by providing the means for continuous product feedthrough. For applications requiring a collet, several shaft options are available to easily interface to existing machine designs.

Aerotech manufactures a wide range of matching drives and controls to provide a fully integrated and optimized solution. Aerotech's high-power brushless amplifiers are available in several convenient packages and the controller options range from stand-alone indexers to sophisticated PC-bus-based controllers with unmatched contouring routines and system tools.
