Aerotech’s ASRT series rotary stages guarantee operation in hostile environments involving washdown, dust or mist spray, or where coolants must be used as a part of a machining process.

They feature direct-drive brushless servomotor technology for precise zero backlash positioning in an IP66 sealed design.

The ASRT series is available in three nominal widths of 185, 245 and 300mm in a dual-bearing design that can support axial loads up to 175kg while maintaining a tilt error motion of less than 3arc/sec.

A low-friction seal between the fixed base and rotating tabletop minimises hysteresis due to direction reversal to allow precise angular positioning and high speed performance.

A bidirectional repeatability of less than 1arc/sec is specified for the optical encoder feedback version, while a magnetic encoder version available on the smaller stages offers less than 10arc/sec.

The use of non-contacting motor and encoder technologies helps contribute to a long life with low maintenance scheduling and particularly suits applications with frequent direction changes, such as sensor test and range tracking equipment.

Both standard and HALAR-certified accuracy options are available for best accuracy to within 2arc/sec for the optical encoder version, with a positioning resolution of 0.018arc/sec for the largest 300mm width stage.

Due to the high-performance direct-drive brushless and cog-free motor technology used, the stage offers speeds up to 200rpm and acceleration in the order of 150rev/sec2, combined with smooth, low-speed motion and in-position stability.

Users can specify continuous travel or a fixed travel range under 360deg rotation.

Other options include through apertures for all stage sizes, allowing through-hole mounting of additional equipment or services, such as electrical slip-ring assemblies or pneumatic/hydraulic supply lines.

The ruggedised stage construction includes a polymer-based paint finish on an aluminium housing in a choice of colours and the rotating tabletop is finished with a durable hardcoat for maximum protection.

Sealed connectors are standard and further optional accessories include an air-purge variant for increased sealing performance and a desiccant cartridge system to offset condensation.

The standard operational temperature range for the ASRT is 0 to 70C, with the possibility to increase the lower limit to -20C with the air purge and desiccant cartridge options.

A protective cover is also available for horizontal-axis orientation.

The ASRT series can be used individually or as a part of multi-axis linear/rotary stage setups and combined with Aerotech’s advanced motion controls and servo amplifiers as complete motion systems.

Aerotech has a number of complementary linear stages with durable side-seal/hard-top designs that can be combined with the ASRT.

Controller options include the A3200 Digital Automation Platform – a Windows based software-only controller for up to 32 axes of fully synchronised and deterministic high-performance motion and machine control, complete with Firewire interfaced servo drives and optional HMI, PLC and vision-control modules.

The multi-axis Ensemble Epaq is available in a six-axis desktop or 19in rack mount, or packaged as series of discrete panel-mounted intelligent drives for up to 10 axes.

With a full complement of machine I/O plus Ethernet, USB and IEEE488 interfacing, the Ensemble can be configured with linear or PWM stage servo amplifiers or alternatively with stepper motor drives.

Single-axis applications can be accommodated with standalone, panel-mounted Soloist – a high-performance motion controller with integrated servo drive.

All Aerotech controls include comprehensive diagnostics and commissioning facilities with programming options including .NET, RS-274 G-code, high level Aerobasic or Labview.

Aerotech motion systems are supplied as fully tested assemblies complete with motor power and encoder cables, with optional machine frames and bases.

Full performance- and calibration-related documents are included and for straightforward commissioning, and all motor-parameter setup data for the system is provided, along with product training and comprehensive technical support.
