Aerotech: Linear Motor Drive Precision Stage (PRO190LM Series)

Linear Stages

Aerotech manufactures a large selection of positioning stages including linear stage models that utilize our own brushless linear direct-drive servomotors, as well as ball-screw models driven with Aerotech brush or brushless rotary motors. Innovators in linear stage design, manufacture and integration, Aerotech builds linear positioning stages for high-performance applications in industrial robots, fiber optics and photonics, vision systems, machine tools, assembly, semiconductor equipment, medical component laser machining, laser micromachining, electronic manufacturing, and other industrial automation applications.

Aerotech linear stages are available in X, XY and XYZ combinations to meet your motion requirements.

Design Features

The PRO190LM is part of Aerotech’s second-generation PRO-LM stage series with many improvements and added features. When higher stiffness, load capacity, and improved geometric performance is required, the PRO190LM is a solid alternative to the PRO165LM. Building on the fundamental precision design of other PRO-LM series stages, the PRO190LM is the ideal choice in many high-performance applications.

Rugged Mechanical Construction

A long-life recirculating linear guide bearing system and a low-friction sealing solution make the PRO190LM an attractive solution for industrial applications such as laser machining. The basic external construction of the PRO190LM design provides protection from debris while the side-seals prevent dirt and particulates from entering the stage. The curved hard-cover design provides a natural shape that prevents excessive debris from collecting on the stage.

Precision Motion Performance

The PRO190LM series stages are optimized with high-precision, non-contact linear encoders that are protected from debris by the stage sealing system. Precision recirculating linear bearings along with machining and assembly craftsmanship enable excellent geometric performance specifications.

Incremental and absolute encoders are available as standard options and enable minimum incremental motion down to 5 nm and sub-micrometer repeatability. The optional HALAR factory calibration improves positioning accuracy down to ±1 μm.

Direct-Drive Linear Motor

Aerotech’s high-power U-channel linear motors drive the PRO190LM. 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. As with all Aerotech linear motor stages, the linear motor has zero backlash, no windup, zero friction, and excellent dynamic responsiveness.

Design and Integration Flexibility

The PRO190LM is designed with many standard features and options that make the design incredibly flexible and allow it to be easily tailored to a specific application. The PRO190LM is available in 10 different models with travels ranging from 100 mm to 1000 mm and speeds up to 2 m/s. Configurable cable management solutions are available for single and multi-axis systems as standard options.

The base mounting holes are accessible from the outside of the stage allowing for easy mounting. 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 hardcover. Tabletops with hole patterns that allow the direct attachment of Aerotech’s ADRS, ACS-LP, ADRT, ACS, and AGR rotary stages are also available.

The PRO190LM series is also available with cleanroom preparation and vacuum versions.
