The ABRS is designed to meet the exacting requirements of wafer inspection, high precision metrology, x-ray diffraction systems, optical inspection and fabrication, and MEMS/nanotechnology device fabrication.
The design of the ABRS series direct-drive rotary stage has been optimized to minimise stage height. The low profile of the stage reduces the effective working height of the system, minimising "stack-up" related errors. In addition to the low overall height, the ABRS series provides a clear aperture that can be used for product feed-through, laser beam delivery, cable clearance or application-specific requirements.
The ABRS design features large air-bearing surfaces for high stiffness and load capacity, producing not only excellent axial and radial error motions but outstanding tilt error motion, as well. The resultant face error motion is significantly better than other rotary air-bearing tables and spindles, greatly benefiting applications requiring exceptional planar performance.
To maximise positioning performance, the ABRS series utilises Aerotech’s S-series slotless, brushless motor. The motor uses an advanced magnetics circuit design to produce high torque output with minimal heat generation. The slotless design is inherently zero-cogging and torque ripple-free. This makes ABRS stages ideal for applications requiring smooth scan velocities at low or high speeds.
Design Features of the ABRS Rotary Stages Include:
Direct-drive, slotless, brushless servomotor
Zero cogging motor for outstanding velocity stability
Outstanding error motion and wobble performance
Direct coupled, high-accuracy rotary encoder
Low-profile planar design
No mechanical contact
