Aerotech has added an ANT linear positioning stage to its high-precision nano-Motion Technology (nMT) range.
The ANT130-L brings higher load capacity and increased travel of up to 160mm, while maintaining precision, rapid acceleration, high speed and 1nm resolution.
The ANT130-L linear positioning stage has a nominal width of 130mm and is available in four travel ranges of 35mm, 60mm, 110mm and 160mm
The ANT130-L employs a similar advanced design to other ANT (Aerotech NanoTranslation) series linear stages benefiting from anti-creep cross-roller bearings, a centre-driven brushless/non-cogging linear servomotor and 40MHz linear encoder processing.
With zero-backlash and no hysterisis, this friction-free drive method is combined with real-time axis calibration using a choice of Aerotech's motion controllers to provide dynamic performance advantages and improved precision over traditional lead-screw and ceramic, motor-driven stages.
The ANT130-L has a nominal width of 130mm and is available in four travel ranges of 35, 60, 110 and 160mm - each with a choice of two certified accuracy grades between +/-2um and +/-250nm to suit high- or ultra-high precision performance.
In-position stability is measured at 3nm; positioning resolution is 1nm and repeatability to 50nm.
In terms of speed and acceleration, the ANT130-L returns up to 350mm/sec and 1g.
The robust aluminium two-piece stage includes a durable black hard-coat finish to provide high stability with a load carrying capacity of up to 12kg across the range.
Long working life with minimum maintenance is assured with non-contacting linear servomotors and encoders, plus a moving magnet track design that eliminates the need for cable management - leading to a 30,000 hour MTBF life specification.
The ANT130-L may be supplied as a single-axis solution or with other Aerotech ANT series high-precision stages for complete multi-axis systems along with goniometric, rotary and vertical translation stages.
Options include the A3200 Automation Platform with Npaq drives or the Ensemble series for multi-axis positioning systems and the Soloist series for single-axis applications.
A choice of servo-drive technologies includes PWM amplifier stages for highest dynamic performance and Aerotech has developed its own wide-bandwidth linear servo amplifier technology for low jitter, zero crossover distortion and ultra-quiet EMC characteristics.
Aerotech's PC-based A3200 Automation Platform is a software-only multi-axis controller with machine control modules for HMI, Vision and PLC for up to 32 axes.
The deterministic, high-speed architecture is based on the IEEE-1394 Firewire protocol network delivering distributed and tightly synchronised motion and I/O control in combination with Aerotech's Ndrive digital servo amplifiers.
For a fully integrated desktop or 19in rack-mounted motion control solution, Aerotech's Ensemble combines up to nine axes of motion and machine controls with Ethernet and USB.
Soloist is a single-axis, panel-mount, integrated motion-control and servo amplifier that may be networked for multi-axis applications with full I/O sequencing.
All Aerotech motion controllers feature software commands that are designed to optimise performance, along with diagnostic, commissioning and programming options that include AeroBasic, Visual Basic C, C++, with higher level Windows-based ActiveX components with C++, VB and .NET class libraries.
Aerotech motion systems are delivered with documentation and test calibration information included, and supplied fully tested and pre-commissioned with setup parameters pre-loaded into the controller.
