New brochure for extensive range of rotary stages
As part of its wide range of advanced motion controls and micropositioning products, Aerotech manufactures a large selection of rotary stages for industrial production and test, and scientific research applications. In its newest brochure, the company has brought together an important collection of rotary stages in one single 36-page resource that will facilitate the comparison of specifications and prominent characteristics for 11 different rotary stage types - from high-performance, low-profile stages with air bearings and direct-drive motors, to large-diameter, large-aperture, gear-driven stages.
Aerotech's rotary stages form a significant part of single- and multi-axis positioning systems, complete with advanced motion controls that are used across industrial automation, photonics, medical device, semiconductor, laser micromachining and many other industries. Each rotary stage requirement differs in terms of precision, dynamic performance and budget, and these constraints are reflected in the bearing, drive and build construction technologies used.
The new brochure covers the top-end ABRT and ABRS ranges with brushless and slotless direct-drive motors and air bearings for outstanding error motion and wobble performance suited to the exacting requirements called for in wafer inspection, DVD mastering and high-precision metrology. For applications where heavier loads, higher torques and increased industrial durability are called for, Aerotech ADRT and ADRS stages introduce similar wobble and runout performance with direct-drive motors and angular-contact bearings. For applications where large through apertures are required (up to 325mm), the ALAR range provides excellent accuracy and repeatability with continuous rotation speeds up to 300rpm - much higher speeds and consequently much higher production throughput than gear-driven, high-resolution stages.
More options
Other stages featured in the brochure include the specialist ANT95 and 130 miniature stages that address the high-resolution (0.01 arc-sec) positioning needs of MEMS and nanotechnology manufacture and test applications. Other specialist areas are represented with the fully sealed (IP66) ASRT stages that have been developed for hostile environment applications such as laser micromachining and are impervious to cutting fluids. Aerotech's ARMS series feature mechanical bearings and direct-drive technologies, specifically aimed at highly accurate motion generation applications such as rate tables and gyro/accelerometer sensor calibration and test. Finally, the AGR series includes a more traditional mechanical bearing and worm-gear design that has a very large aperture and can fulfil general-purpose rotary positioning applications in industry and in the laboratory, at a very competitive cost.
The new Rotary Stage brochure is available as a PDF download from the www.aerotech.com website. It also includes a brief overview Aerotech's advanced motion controls and its capabilities across other market areas such as alternative energies, medical device and life sciences, government and educational research, and electronics manufacture, assembly and test.
