The ALS1000 is a compact, high-performance
stage that is as accurate as it is versatile. It provides a small
cross section, cost-effective alternative for precision applications
where a small footprint and environmental protection are required.
A linear motion guide bearing system, two-axis internal cable
management, and high-performance brushless servomotor make the
ALS1000 the stage of choice in industrial applications such as
laser machining, medical component manufacturing, and other applications
requiring high accuracy in a production environment.
Construction Features
Sealed linear motion guide bearings with integral wipers are incorporated
to provide excellent payload capability and long life. Both the
metal waycover and tabletop are treated with a hardcoat (Rockwell
62 hardness) that is scratch-resistant and provides outstanding
protection in the harshest applications. An optional air-purge
fitting is available that allows air to be forced into the body
of the stage to create a positive internal pressure that resists
particulates from entering the stage. The tabletop utilizes stainless
steel Helicoil™ inserts to protect mounting holes against
thread wear. Optional stage finishes are available, including
electroless nickel plating.
Linear Motor Drive
Aerotech’s high-power, cog-free, BLMC series linear motor
drives the ALS1000. The non-magnetic forcer coil provides high
force with zero cogging for super-smooth velocity and position
control. This zero cogging design is ideal for applications requiring
outstanding contour accuracy and smooth velocity profiling. As
with all of Aerotech’s ALS series linear motor stages, the
linear motor has zero backlash, no windup, zero friction, and
outstanding system responsiveness.
The magnetic field of the linear motor is totally self-contained
within the U-channel design. Most high-performance applications
cannot tolerate the stray magnetic fields generated by flat motor
magnet tracks.
Cable Management System
Extensive R & D has resulted in an optimized 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 to the stages, providing a turnkey system. External CMS
is available for three-axis systems. Custom configurations are
common and are readily available.
High Performance
Noncontact linear encoders with micron-level repeatabilities are
standard on all ALS1000 series stages. Either a line-driver output
or amplified sine-wave output encoder is available. Motor power
and feedback signals terminate in the stage endplate, allowing
for a simple, clean interface.
The optional HALAR factory calibration further increases the standard
accuracy and repeatability. Aerotech manufactures a wide range
of matching drives and controls to provide a fully integrated
and optimized motion solution.
