Description
Design Features
- 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
Noncontact Direct-Drive
The ANT180L 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.
Outstanding Resolution
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 ANT180L 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 ANT180L exhibits the outstanding ripple-free motion required for scanning and inspection applications.
Precision Alignment and Cable Management
ANT180L 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 conne4torized for simple integration into the customer’s machine.
