Aerotech has released a new low profile, high speed rotary stage that offers a compact alternative to traditional positioning spindles. Capable of a top speed of 2500 rpm and with a fundamental angular resolution of 3.6 arc-sec, the ADRH 100 features backlash and cog free, direct-drive servo motor technology with a directly coupled precision professional encoder for excellent servo bandwidth and maximum stiffness.
The innovative mechanical suppliers of bearing system makes use of Aerotech’s highly developed rotary stage design expertise to maintain a low height whilst providing minimal runout and wobble. With synchronous error motions of 2 μm, asynchronous error motions of 4 μm and a tilt error of just 15 arc-sec, the ADRH 100 has an overall height around 55 mm and a tabletop diameter of less than 105 mm.
The new stage has been developed for high precision bidirectional speed and position control, high speed motion contouring, and rapid angular position indexing applications as required in disk drive testing, precision wafer inspection and high speed imaging. The stage will outperform the acceleration and positioning stability performance of traditional gear and professional belt driven rotary spindle mechanisms - offering an extremely long life and low maintenance solution for high throughput 24/7 production and test applications.
