Q-545: nanometer-precise compact linear positioner from PI

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. In addition to a number of standard product variations with 0.5" and 1" travel, PI stages and drives can be customised for OEM production quantities.

With holding force of 8N and maximum velocity of 10mm/sec, the self-clamping motor design provides long-term power-off position-hold capabilities without the need for a brake -- a space and energy saving advantage.

The stages can be run in open and closed-loop. A high-resolution option with integral linear position encoder providing 1 nanometer resolution is also available. Nonmagnetic versions and an ultra-high-vacuum version for pressures of 10-9hPa are optional.

Features and advantages:

• Self-clamping high-precision ceramic motor
• XY configurations
• Linear encoder available
• 8N feed force
• 13 and 26mm travel range
• 10mm/sec max. velocity
