Goniometer stages prevent backlash
Aerotech's ANT-20G goniometer stages have a curvilinear direct-drive brushless servomotor that provides cog-free smoothness, solid in-position stability and zero backlash performance.
Software simulates complex motion
Detailed motion analysis tools and iterative learning control algorithms reduce following error and cycle times over multiple runs.
Guide covers automation range
An overview of Aerotech's range of motion controllers includes the A3200 Digital Automation Platform, a software-only, PC- based, Firewire-interfaced system.
Using direct drive linear motor technology, Aerotech defies logic with a linear motor that provides incredible repeatability of +/-0.05arc-sec and gives a 20-degree angular motion that is accurate to an impressive 10arc-sec.
When used with Aerotech's MXH multiplier, the ANT-20G stage provides a positioning speed of 150 degrees per second, even at 0.058arc-sec resolution.
The resolution is improved still further to an amazing 0.0018arc-sec when the ANT stage is driven by Aerotech's new Automation 3200 software-only motion controller.
Linear encoder feedback is used to ensure an exceptional position reference.
The noncontact, noncogging direct-drive technology gives a higher frequency response and unlike worm or piezodrive stages, the ANT-20G does not require periodic adjustment or maintenance.
This represents a significant step towards trouble free operation that is matched by ease of installation.
A benefit is the small size of the ANT goniometer which measures 95 x 81 x 38mm and features high precision ball bearings enabling loads up to 1.5kg.
The critical elements of the ANT-20G goniometer, as with all other ANT series nanopositioners, were selected to operate in a 24/7 manufacturing environment.
A range of direct drive rotary stages, Aerotech's ADRT Series, is also available. Request a free brochure from Aerotech ...
