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 of the ASR1000
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 MXH 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.
