Ultra-quiet linear servo drives
High speed, real-time axis calibration
Aerotech's Nanotranslation Crossed-Roller (ANT-LX) stages incorporate
direct-drive technology to offer the robust, accurate, and high-speed positioning
necessary for mass production of precision devices. ANT-LX performance includes
2 nm linear resolution, ±0.3 µm accuracy, ±0.05 µm
repeatability, 5 g acceleration, 500 mm/s velocity, a maximum load up to 8 kg,
and a standardized, universal base-mounting pattern that allows the use of this
flexible stage family in a wide range of configurations.
Noncontact Direct-Drive
ANT-LX stages utilize Aerotech's advanced direct-drive technology to achieve
the highest level of positioning performance. Aerotech's direct-drive technology
is non-cogging, noncontact, high-speed, high-resolution, and high-accuracy,
and the use of crossed-roller bearing elements allows high precision, small
incremental moves to be accomplished reliably and repeatably. This compact linear
stage is 90 mm wide by 33 mm high by 102 mm long for the 25 mm travel version
and 144 mm long for the 50 mm travel version. This extremely small footprint
offers distinct advantages in fiber optics, photonics, MEMS, scanning, and any
applications that require ultra-smooth, high precision motion in limited space.
Flexible System Design
The universal mounting and tabletop patterns allow for easy integration of two,
three, or more axes. Both 25 mm and 50 mm travel versions can be integrated
without the need for interface plates, preserving low profile system designs.
The ANT-LX may be combined with other ANT series stages (vertical lift, rotary,
goniometer) to create a complete multi-axis motion platform.
System Characteristics
Outstanding accuracy, position repeatability, and in-position stability require
high system resolution. The ANT-LX stage's industry-leading 2 nm closed-loop
resolution provides this high level of performance. Advanced, real-time axis
calibration systems allow the highest level of system accuracy. High-speed,
40 MHz electronic circuitry enables extremely fast positioning, over 500 mm
per second, even at 2 nanometer resolution. Excellent in-position stability,
assisted by high-quality, no-creep linear bearings, enables virtually maintenance-free
operation over the life of the product. Aerotech's direct-drive technology
has no hysteresis or backlash, enabling accurate and repeatable nanometer-scale
motion.
A Complete Motion Solution
Aerotech offers a complete motion solution by offering advanced single and multi-axis
motion controllers, linear and PWM drives, calibration and performance documentation,
and all accessories necessary for your system.
