The ALS20000 linear positioning stage was designed to have exceptional velocity control, low vibration, high accuracy and excellent throughput, making it the ideal solution for imaging and precision inspection applications.
Design Features of the ALS20000 Mechanical Bearing Direct-Drive Linear Stage include:
Protective metal waycover
450 mm wafer compatible
Integral cable management system
Ideally suited for cleanroom applications
Compact, high-performance, linear motor stage
Superior velocity control for imaging and scanning applications
The ALS20000 series linear 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.
Recognising the importance of stage stiffness, the ALS20000 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 utilise an iron-core flat motor design, the ALS20000 positioning stage is driven by a high-power ironless forcer and U-channel magnet track. This design is superior in high-performance applications. Since the BLM 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 BLM 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 BLM's 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.
