Low profile, high speed rotary stage provides solution for compact positioning spindle applications

The innovative mechanical 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 belt driven rotary spindle mechanisms - offering an extremely long life and low maintenance solution for high throughput 24/7 production and test applications.

The ADRH 100 is also available in custom modified OEM versions where further space saving may be made by adapting cable management, mounting configuration or other characteristics to suit the customer's mechanics.

A wide range of motion controls and high performance servo drives are available for use with the ADRH 100. Aerotech's A3200 Digital Automation Platform is a PC based software machine control system that combines motion control, HMI, PLC and vision control modules. Based upon the industry standard Firewire® communication network, it may control up to 32 axes of high speed motion via its distributed control architecture with deterministic position, velocity, and time commands to Aerotech's DSP based Ndrive digital servo amplifiers. The A3200 is built to simplify complex, tightly synchronised motion and machine control functions with a choice of software including powerful .NET programming, RS-274 G-code, high level AeroBASIC™ or optional LabVIEW™.

Aerotech's SoloistTM standalone digital servo controller range is an integrated motion control and PWM brushless servo amplifier for use as a single axis solution or as part of a coordinated point to point multi-axis motion system as an Ethernet based distributed drive with high level or .NET programming capability.

For standalone multi-axis motion control, Aerotech's Ensemble™ Epaq is a competitively priced, fully integrated 6-axis desktop or 19 inch rack mounted motion control and drive system. With integral 10 A peak digital PWM or linear amplifiers and machine I/O, the Epaq is capable of driving and controlling linear and rotary brushless, brushed or micro-stepping motors and may be expanded to control a further three external drives, offering 9 axes of completely co-ordinated motion and machine control.
