New Linear Stages for Precision Motion, Automation and Positioning Applications
PI USA has introduced three new families of motorized linear stages tailored for precision automation, motion control, and positioning applications. All three product lines are powered by non-contact, 3-phase linear motors and are equipped with integrated direct-measuring linear encoders. Absolute measuring encoders are available for two of the three linear stage families.
V-141 - Economical and Compact Linear Stages
The V-141 linear stage family, developed by PI USA's engineering team, is the smallest and most economical among the new stages. Currently available with two travel ranges of 25mm and 50mm, it offers excellent straightness and flatness of 1µm and bidirectional repeatability of 0.1µm, with a maximum velocity of 500mm/sec. The 25mm variant boasts a compact footprint of only 80x80mm, making it ideal for space-constrained applications.
V-571 – For Ultra-High Precision Nanopositioning and Alignment Applications
The V-571 family of nanopositioning linear stages is specifically designed for applications requiring extreme accuracy and geometric performance. This nanopositioning stage excels with 0.5µm straightness and flatness per 50mm travel along with pitch and yaw of 50µrad and 25µrad, respectively. When calibrated with an A-81x motion controller, the V-571 linear stages achieve guaranteed positioning accuracy of 100nm and bidirectional repeatability of +/-60nm. Applications include sample inspection, precision micro- assembly, semiconductor inspection and metrology, photonics alignment, as well as mass-production of ultra-high precision components.
V-827 – Wide-Body Linear Stage for Heavy Loads
The V-827 family of wide-body linear stages is tailored for positioning and automation applications involving larger motion ranges, objects and loads. With travel ranges up to 1m, the wide body design makes the stage ideal as base for multi-axis setups, offering higher stability and preventing deflection errors of a mounted Y-axis better than narrower base stages. V-827 stages can carry loads up to 150kg and achieve a maximum velocity of 2m per second. Similar to the other motorized linear translation stages mentioned above, the V-827 provides maximum performance when used with our A-81x or A-82x series of EtherCat®-based motion controllers.
