Aerotech's new direct-drive linear motor stage, the ALS1000, offers
all of the accuracies associated with direct-drive architecture in combination
with a compact and sealed design, internal cable management and impressive performance.
It promises Aerotech's quality guarantee but without the cost implications of
its most precise stages.
With its small cross section and load a capability of 50Kg, the ALS1000 offers
a cost-effective solution for precision markets such as laser machining and
medical device manufacturing. Indeed, it is ideal for all applications that
demand a small footprint and environmental protection in combination with outstanding
contour accuracy and smooth velocity profiling.
Aerotech's high-power, cog-free BLMC Series linear motor provides the power.
Its ironless forcer coil offers high force with no attractive force and zero
cogging for super-smooth velocity and position control. And, as with all of
Aerotech's ALS Series linear motor stages, it has zero backlash, no windup,
zero friction and outstanding system response. Using sealed, high-preload LMG-type
bearings, a motion system with a higher system bandwidth is created and pitch,
roll and yaw errors are minimised. A particularly clever element of the design
is that the motor's magnetic field is totally self-contained within the U-channel.
Some high-performance applications cannot tolerate stray magnetic fields.
Both the metal way cover and tabletop are treated with a Teflon-impregnated
62 Rockwell hardcoat that is scratch-resistant and provides outstanding protection
even in the harshest environment. Other stage finishes are available
as options, including electroless nickel plating. Users also have the option
of an air-purge fitting that can be used to create a positive internal pressure
preventing particulate ingress in heavy applications.
Extensive R&D has resulted in an optimised cable management system (CMS)
that is designed for millions of cycles of maintenance-free operation. In single
and two-axis systems, the CMS is completely internal. An external CMS is available
for three-axis systems and custom configurations are readily available.
Non-contact linear encoders with sub micron-level resolutions are standard
on all ALS1000 series stages. Either a line-driver output or amplified sine
wave output encoder is available to allow signal multiplication for higher resolutions.
Motor power and feedback signals terminate at the stage's endplate, creating
a simple, clean interface. The optional HALAR factory calibration further increases
the standard accuracy and repeatability. Aerotech also manufactures a wide range
of matching drives and controls to provide a fully integrated and optimised
motion solution.
Like the majority of Aerotech's motion solutions, the ALS1000 is offered with
simple plug-and-play installation it is optimised for use with complimentary
controllers, amplifiers and cables. When ordered with the complimentary hardware,
Aerotech provides all drawings, cables, parameter files and comprehensive system
documentation creating a complete, out-of-the-box solution saving users
valuable time on set up and installation. The system is then backed up by comprehensive
local technical support throughout its life, no matter where it ends up.
Aerotech is a World leader in the design and manufacture of advanced motion
components. It is unique in its ability to supply complete systems in which
each component is matched precisely not only to the application but
also to each other. This product synergy ensures quality, reliability, accuracy
and the most effective cost of ownership.
