Aerotech: Linear Motor Drive Precision Stage (ALS5000 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.

ALS5000 Mechanical-Bearing Direct-Drive Linear Stage

Design Features

The ALS5000 was designed to meet the needs of the most demanding applications. A rigid base, fully-sealed metal way covers and high-power linear motor make the ALS5000 the stage of choice in laser machining, ceramic scribing or any other application requiring high accuracy in a production environment.

Rugged Construction

The greatest attention to detail is evident in all aspects of the ALS5000 design. The tabletop utilizes stainless steel Helicoil® inserts to protect mounting holes against thread wear.

An integral metal waycover is provided to protect the stage from hot sparks or debris. Both the metal waycover and tabletop are treated with a hardcoat (Rockwell 62 hardness) that is scratch-resistant and provides outstanding protection in the harshest applications.

To further provide the stage with protection from a caustic environment, the ALS5000 utilizes Aerotech’s unique tensioned side-strap system. The straps are in a vertical orientation that prevents debris from accumulating on top of them and are tensioned to create a tight seal. An optional air-purge is available that allows air to be forced into the body of the stage. This creates a positive pressure that prevents any particulate, no matter how fine, from entering the stage. To aid in system assembly, the base mounting holes are located outboard of the stage. Therefore, the stage can be mounted without removing the hardcover.

High Performance

The base of the ALS5000 is machined from special aluminum alloy tooling plate to provide high stiffness and long-term stability. Sealed linear motion guide bearings with integral wipers are incorporated to provide excellent payload capability and long life, even with heavy offset loads.

Noncontact linear encoders with submicron repeatabilities are standard on all ALS5000 series stages. Optional HALAR and HALSF factory calibration options are available that further increase the standard accuracy, straightness and flatness specifications to even finer precision.

Linear Motor Drive

Aerotech’s high-power, cog-free, BLM series linear motor drives the ALS5000 to a maximum speed of 2 m/s and acceleration of 3 g. This zero cogging design is ideal for applications requiring outstanding contour accuracy and smooth velocity profiling. As with all Aerotech ALS series linear motor stages, the linear motor has zero backlash, no windup, zero friction and outstanding system responsiveness.
