Smallest piezo linear motor/translation stage
PI's patented P-652 piezoelectric linear-motor driven translation stage is significantly smaller than other miniature-stages and provides very high speed and resolution
The stage consists of only four parts and can replace classical drive elements like rotary motor/leadscrew assemblies or electromagnetic linear motors in a micro-system.
Measuring only 9.0x6.5x2.4mm, the new P-652 stage offers a travel range of 3.2mm and can move at velocities of up to 80mm/sec - almost ten times faster than other micro-stages.
Sub-micron resolution, combined with a high holding force of 20grams, are state-of-the-art figures for a stage of these minute dimensions.
Because no leadscrews or other rotating parts are involved P-652 systems are absolutely backlash-free.
Due to its ultrasonic motor design, power consumption in steady state conditions is zero and no external brake is necessary to maintain a stable position.
Typical applications: P-652-series PILine piezoelectric ultrasonic motor drives are ideal for OEM applications where quantities are high, space is limited and masses are small.
The systems were optimised for moving small objects such as fibres, optomechanical components, micro-medical devices, micromechanics (or Mems) fast and precisely.

Brochure presents a variety of compact and sub-compact positioning stages, featuring sub-micron to sub-nanometer precision and closed-loop position feedback with linear encoders and capacitive gauges
These closed-loop stages were designed for high-dynamics precision motion control applications, like those in biotechnology; laser beam control; scanning; optics and lens finishing; and fibre optics
