Miniature rotary table suits stepper or servo motors
LG Motion Ltd is adding a new miniature rotary table 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 rotary stage joins a modular family of linear and vertical positioners that combine with motion controllers, drives and interfacing components for complete automated positioning systems.
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, while a high-specification main bearing arrangement supports a centrally located load of up to 1kg. With a positioning accuracy of 0.05deg and repeatability to better than 0.01deg, the table's micropositioning capability is determined by the drive technology with a maximum resolution in the region of 0.001deg. A 10mm diameter bore provides convenient feed-through capability for electrical wiring, beamlines, slip rings or optical components.
Like other models in the range, the LGR-50 has a 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 tabletop diameters to 250mm 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.
