PI (Physik Instrumente), a top provider of precision motion control and positioning solutions, has released a new compact linear stage, just 45 mm wide, that combines positioning accuracy with higher force and velocity than conventional inertia drives. The Q-545 provides advantages for use in research and OEM instrumentation that require positioning precision and alignment, such as photonics, bio-technology, nanotechnology, precision-optics, life-sciences, or medical design.
How it works
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. In addition to a number of standard product variations with 0.5” and 1” travel, PI stages and drives can be customized for OEM production quantities.
An integrated optical reference encoder and limit switch provide further positioning control and accuracy for this compact stage with 5 nm resolution. DC servo motor versions are available on request.
Self-clamping at rest, high force and stability
With holding force of 8 N and maximum velocity of 10 mm/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.
Nanometer precision encoder option
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 10-9 hPa are optional.
