Aerotech: Linear Motor Drive Precision Stage (ALS25000 Series)
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.
ALS25000 Mechanical-Bearing Direct-Drive Linear Stage
Protective metal waycover and side seals for harsh environments
Integral cable management system
High-performance direct-drive linear motor for superior servo performance
Compact footprint for limited space requirements
The ALS25000 was designed to have a low profile, with protective metal waycover and side seals, intelligent cable management, exceptional velocity control, low vibration, high accuracy and excellent throughput, making it the ideal solution for demanding applications in dirty environments.
High Performance in a Compact Package
ALS25000 series stages incorporate the highest quality materials and design elements. The result is a high-reliability linear stage with excellent accuracy, straightness and flatness performance and a virtually unlimited, trouble-free service life.
Recognizing the importance of stage stiffness, the ALS25000 linear bearings are supported by the maximum cross-section possible while still maintaining an overall low profile. Outstanding system straightness and flatness are obtained, particularly in XY configurations.
Unlike other linear motor stage designs that utilize an iron-core flat motor design, the ALS25000 is driven by a high-power ironless forcer and U-channel magnet track. This design is superior in high-performance applications. Since the forcer is ironless it is a cog-free design. The lack of cogging enables extremely tight velocity control as well as superior contour motion profiles without sacrificing speed or acceleration. The magnetic field of the linear motor is totally self-contained within the U-channel design. Most high-performance applications cannot tolerate the stray magnetic fields generated by flat motor magnet tracks.
The magnet track is composed of opposing rows of high-power magnets that help to generate high output forces. This approach eliminates the need for an iron-based core, which has an inherent magnetic attraction between the forcer and the magnet track. This attractive force presents an additional load to the bearings that reduces stage life and performance.
Extensive R&D has resulted in an optimized cable management system (CMS) that is designed for millions of cycles of maintenance-free operation. Designed to provide a turnkey system for both single- and multi-axis systems, upper-axis cabling is incorporated into the overall system CMS. To facilitate integration into the final system, a spare 25-pin D-connector and cabling are included for customer use. Custom configurations are common and are readily available.
