紧凑封装
The design of the ABRS series direct-drive rotary stage has been optimized to minimize stage height. The low profile of the stage reduces the effective working height of the system, minimizing "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.
优异的机械设计
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.
无刷直驱
To maximize positioning performance, the ABRS series utilizes Aerotech s S-series slotless, brushless motor. The motor uses an advanced magnetic 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.
精确定位
An optical encoder is standard with the ABRS. When coupled with Aerotech s feedback multipliers and controls, resolutions of <0.03 arc second are achievable.
定制化设计
Custom versions of the ABRS are available for rate table and inertial guidance test-stand applications.
