Miniature rotary stage added to position stage range
26 January 2016
LG Motion has added a new miniature rotary stage to its 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 family of modular linear and vertical positioners that combine with motion controllers, drives and interfacing components for complete automated positioning solutions.
The LGR-50 is designed for use 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 whilst a high specification main bearing arrangement supports a centrally located load of up to 1 kg. With a positioning accuracy of 0.05° and repeatability to better than 0.01°, the table‘s micropositioning capability is determined by the drive technology with a maximum resolution in the region of 0.001°. A 10 mm 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 and has been successfully used as part of a multi-axis linear and rotary customised 10-6 torr motorised positioning system for an optical test application.
