New miniature rotary stage expands LG Motion position stage range

LG Motion has added a new miniature rotary stage to its competitively priced LG-Series precision positioning mechanics range. With a table-top diameter of 45 mm and a low profile height of just 35 mm, the new LGR-50 joins a modular family of 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 follows other models in the range with its lightweight construction and smart black anodised aluminium finish. The design and durable build quality has been well proven across the LG Motion’s LGR rotary stage range which includes standard models with table-top diameters to 250 mm and load ratings to 500kg.

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. Other customisation options include directly mounted servo motors and feedback encoders, hard stops, work holding fixtures, special interfacing brackets and other specialised components.
