Aerotech: Linear Motor Drive Precision Stage (ANT180-L Series)
Aerotech manufactures a large selection of positioning stages including linear stage models that utilize our own brushless linear direct-drive servomotors, as well as ball-screw models driven with Aerotech brush or brushless rotary motors. Innovators in linear stage design, manufacture and integration, Aerotech builds linear positioning stages for high-performance applications in industrial robots, fiber optics and photonics, vision systems, machine tools, assembly, semiconductor equipment, medical component laser machining, laser micromachining, electronic manufacturing, and other industrial automation applications.
Aerotech linear stages are available in X, XY and XYZ combinations to meet your motion requirements.
ANT180-L Mechanical-Bearing Direct-Drive Linear Stage
Noncontact, non-cogging, frictionless direct-drive
Zero backlash or hysteresis
High resolution, repeatability and accuracy
Anti-creep crossed-roller bearings
Travel to 360 mm
Integral cable management for multi-axis systems
The ANT180-L continues the expansion of Aerotech’s line of high precision crossed-roller-bearing stages. With its nanometer resolution, superior bi-directional repeatability and exceptional low-velocity performance, it is the ultimate solution for high-accuracy alignment, measurement, scanning and other demanding applications.
The ANT180-L is driven by a high-power linear motor with ironless forcer and U-channel magnet track. The direct-drive linear motor drives the stage to a peak unloaded acceleration of 2 g and maximum velocity of 500 mm/s. Because the forcer is ironless, it is a cog-free design that provides exceptional velocity control.
The direct-drive linear motor and high-accuracy linear encoder make possible outstanding step-to-step resolution when coupled with an Aerotech control system. This is critical in spectroscopy, optical delay line and other applications. Furthermore, the linear motor and high resolution linear encoder system also provide excellent in-position stability.
Superior Geometry for High Performance
Its large cross-section provides a robust and stable base axis for multi-axis systems. Aerotech’s ultra-stiff construction and compact two-piece design result in a stage with unparalleled geometric tolerances. As a result, the straightness and flatness typically are <±1 μm over the entire travel.
Designed for smooth, vibration-free motion, the ANT180-L utilizes precision anti-cage-creep crossed-roller bearings for outstanding smoothness of motion. Since neither the bearing system nor the drive system utilize any recirculating elements, the ANT180-L exhibits the outstanding ripple-free motion required for scanning and inspection applications.
Precision Alignment and Cable Management
ANT180-L series stages are easily configured into XY and other multi-axis assemblies. Precision orthogonality alignment to 5 arc seconds and multi-axis cable management systems (CMS) are standard options. We include all customer-required cables, air hoses, etc. in our CMS bundle to facilitate incorporation into the final system. Both ends are fully connectorized for simple integration into the customer’s machine.
