The PRO280LM is the full-sized offering in Aerotech’s
PRO-LM series of high performance, cost-effective, and
versatile linear motor stages. The PRO280LM is a good
alternative to the PRO225LM for applications that require
higher thrust force, higher stiffness, or have larger
payloads. A linear motion guide bearing system and high performance
brushless linear servomotor make the
PRO280LM 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 that is scratch-resistant and provides
outstanding protection in the harshest applications. The
tabletop utilizes stainless steel Helicoil™ inserts to protect
mounting holes against thread wear. Several tabletop
options are available for metric or English mounting, as
well as for direct interface with our popular ADRS, ADRT,
and AGR rotary stages. In addition, configurable cable
management options are available for single- or multi-axis
systems.
Linear Motor Drive
 Aerotech’s high-power,
cog-free, BLMH series
linear motor drives the
PRO280LM. The nonmagnetic
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
Aerotech 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. Many
high-performance applications cannot tolerate the stray
magnetic fields generated by flat motor magnet tracks.
High Performance
Noncontact linear encoders with micron-level
repeatabilities are standard on all PRO280LM series stages.
Either a line-driver output or amplified sine-wave output
encoder is available.
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.
