32 mm Wide x 7 mm High: PI’s Newest Compact Rotary Stage

Precision nanopositioning systems specialist PI (Physik Instrumente) L.P. recently added a new piezo inertia drive rotary stage to its existing Q-Motion product line of compact linear and rotary systems – the Q-632.

This compact micropositioning drive is only 32 mm wide, 7 mm high, and has a 30 mm turntable diameter with 360° rotation range.

Self-Clamping at Rest, High Stability

The Q-632 delivers precision rotation with minimal incremental motion of 3 µrad in closed-loop operation and velocity of 45°/s. The self-clamping motor design provides long-term power-off position-hold capabilities without the need for a brake -- another space and energy saving advantage of the Q-Motion positioner series. All Q-Motion rotation stages are suitable for a vacuum to 10-6 hPa; ultrahigh vacuum-compatible versions are also available on request.

The Q-600 series of miniature rotary stages include the smallest motorized stage that fits on a finger-tip - the Q-614, with a 14 mm diameter turntable and velocity 70° per second.

Open & Closed Loop Variations

The Q-632 offers variety with open and closed loop versions. The closed loop version is equipped with a direct measuring sensor providing 0.75 µrad resolution.

Stick-Slip Gearless Economical Drive System

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.
