Linear Motor Stages offer in-position stability of 3 nm.
April 28, 2009 -
Utilizing non-cogging, non-contact, direct-drive technology with no hysteresis or backlash, Series ANT95-L exhibits 5 g acceleration, 500 mm/s velocity, 50 nm repeatability, and 250 nm accuracy. Use of anti-creep cross-roller bearings allows 5 nm incremental moves to be accomplished. With universal mounting and tabletop patterns, stages are suited for high-precision positioning, disk-drive fabrication, fiber alignment, and optical delay element actuation.
Nanometer Accuracy AND Long Travel Is a Reality with Aerotech's ANT95-L Linear Motor Stage
o Noncontact, non-cogging, frictionless direct-drive - zero backlash or hysteresis
o High resolution (5 nm), repeatability (50 nm), and accuracy (250 nm)
o In-position stability of 3 nm
o Anti-creep cross-roller bearings
o High dynamic performance
o Available in X, XY, XYZ, and many other combinations
Aerotech NanoTranslation (ANT95-L, ANT95-L-H) cross-roller bearing stages combine high speed, accuracy, resolution, repeatability, and reliability into a compact package. As an evolution of the popular ANT stage family, these linear stages exhibit enhanced motion performance such as 5 g acceleration, 500 mm/s velocity, enhanced load capacity, and standardized, universal base mounting patterns that allow the use of this flexible stage family in a wide range of configurations.
Noncontact Direct-Drive
ANT95-L stages utilize advanced direct-drive technology, pioneered by Aerotech, to achieve the highest level of positioning performance with resolution of 5 nm, repeatability of 50 nm, and accuracy of 250 nm. Aerotech direct-drive technology is non-cogging, noncontact, high speed, high resolution, and high accuracy, and the use of anti-creep cross-roller bearings allows ultra-precision (5 nm) incremental moves to be accomplished reliably and repeatably. This unique drive and bearing combination, packaged in an extremely small-profile and footprint, offers tangible advantages in applications such as high-precision positioning, disk-drive fabrication, fiber alignment, optical delay element actuation, sensor testing, and scanning processes that demand smooth and precise motion.
Flexible System Design
The ANT95-L family has universal mounting and tabletop patterns that allow for easy system integration. Two, three, or more axes can be easily combined for flexible system designs and multi-axis configurations.
System Characteristics
Outstanding accuracy, position repeatability, and in-position stability require high system resolution. The ANT95-L industry-leading 5 nm minimum incremental step size provides this high level of performance. Excellent in-position stability assisted by high-quality, anti-creep cross-roller 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.
System Control
To get the most out of your ANT95-L, Aerotech produces award-winning, high performance, single- and multi-axis motion controllers that excel in any application. The Automation 3200, Ensemble, and Soloist controllers are a perfect complement to your high-performance stage.
