Compact Linear and Rotary Stages

AUBURN, Mass., Dec. 21, 2017 — Physik Instrumente LP has announced a line of compact linear and rotary stages driven by ceramic direct-drive motors.
The patented ultrasonic motors provide smooth motion with high resolution and a high dynamic range. The self-clamping motor principle locks the stage into place, devoid of creep, once a target position has been reached. This intrinsic brake-like behavior comes at no extra cost and provides advantages that are not available with classical electromagnetic drive technologies.
Two linear stages with 18- and 22-mm travel are available, as well as an XY stage providing 22 × 22 mm. Several encoder options, from 0.4 µm to 10 nm, are standard. All stages achieve closed-loop peak velocities to 200 mm/s. The rotary stages come with turn-table diameters from 20 to 50 mm, encoder resolution down to 17 µrad and maximum velocity of 720°/s.
