September 1, 2016 - Aerotech announced the addition of two sizes to the PRO-LM (linear motor) series stage line – the PRO115LM and PRO190LM. New features include a linear encoder option on PRO-SLE ball-screw stages, absolute encoder options on both the linear motor and ball-screw stages, and direct mounting to English and metric optical tables.
All PRO series stages employ a long-life recirculating linear guide bearing system and a low-friction sealing solution for long life in industrial applications such as laser machining. The PRO series design provides protection from debris while side-seals prevent dirt and particulates from entering the stage. The curved hard-cover prevents excessive debris from collecting on the stage.
The base mounting holes are accessible from the outside of the stage allowing. Standard mounting holes for both English and metric optical tables are present in all travels. The tabletop is available with both English and metric mounting patterns and can be ordered with brush attachments to clear any debris that may collect on the stage hard cover. Tabletops have hole patterns for the direct attachment of Aerotech’s ADRS, ACS-LP, ADRT, ACS, and AGR rotary stages for multi-axis system design and implementation.
PRO-LM stages are optimized with high-precision, noncontact linear encoders. Incremental and absolute encoders are available as standard options and enable minimum incremental motion down to 5 nm and sub-micrometer repeatability. Optional HALAR factory calibration improves positioning accuracy to ±0.75 μm. Travels range from 50 to 1500 mm for standard models with speeds to 2 m/s.
Aerotech’s high-power U-channel linear motors drive the PRO-LM series. The ironless forcer coil provides high force with zero cogging for super-smooth velocity and position control. This ironless design is ideal for applications requiring outstanding contour accuracy and smooth velocity profiling.
