Miniature rotary stage expands position stage range
30 January 2016
LG Motion has added a miniature rotary stage to its competitively priced LG-Series precision positioning mechanics range.
With a table-top diameter of 45mm and a low profile height of just 35mm, the new LGR-50 joins a modular family of linear and vertical positioners that combine with motion controllers, drives and interfacing components.
The LGR-50 can be used with NEMA 11 or 17 stepper motors - with servo motors or manual drives also available - and features a preloaded 90:1 worm-wheel gear drive with very low backlash. The main bearing arrangement supports a centrally located load of up to 1kg. With a positioning accuracy of 0.05° and repeatability to better than 0.01°, the table's micro-positioning capability is determined by the drive technology, with a maximum resolution in the region of 0.001°. A 10mm diameter aperture provides convenient by-pass for electrical wiring, beamlines, slip rings or optical components.
The LGR-50 is also available as a vacuum prepared version. Other customisation options include directly mounted servo motors and feedback encoders, hard stops, work holding fixtures, special interfacing brackets and other specialised components.
