Physik Instrumente has introduced a new miniaturized, piezo-driven linear positioner; the Q-521.
Joining PI’s existing Q-Motion linear and rotary positioning products, the ultra-compact Q-521 is 21mm wide, and comes with travel ranges of 12mm, 22mm, and 32mm.
Several options are available for the Q-521 stage series, from economical open-loop designs, to low-cost closed-loop versions and high-end feedback sensors providing 1nm resolution.
Vacuum compatible stages, and UHV and a non-magnetic option are also offered.
Stick-slip drive motors, lacking gears, are powered by the natural difference in the static and dynamic friction coefficients found between two surfaces.
This direct linear motion drive principle reduces the number of components that can wear, making the stages more compact, reliable and cost efficient. PI stages and drives can be customized for larger production quantities.
The self-clamping motor design provides long-term power-off position-hold capabilities without the need for a brake.
