Fast Linear Positioning Stage with Voice Coil Drive Provides 270 mm/sec, 0.1 Micron Resolution, by PI (Physik Instrumente)
Date:8/6/2013

Auburn, MA (PRWEB) August 06, 2013

Applications
These closed-loop stages were designed for high-dynamics precision motion control applications, like those in biotechnology; laser beam control; scanning; optics; lens finishing; and fiber optics.

Higher Dynamics & Lifetime than Lead-Screw / Ballscrew Type Drive Mechanisms
V-106 translation stages / scanning systems achieve significantly higher dynamics than leadscrew-based units; scanning frequencies to 20 Hz and above can be achieved. Another advantage of the frictionless voice coil drive is greater reliability and lifetime than screw-type drive mechanisms. For high-throughput positioning applications, the short settling time of less 75 milliseconds for a 5 mm step is a real benefit.

Features

  • Frictionless voice-coil linear motor drive for smooth, ripple-free motion
  • Velocity up to 270 mm/sec (>10 inch/sec)
  • Scanning frequency several 10s of Hz
  • Direct metrology linear encoder with 100 nanometer resolution
  • Travel ranges of 20 mm and 6 mm
  • Precision cross-roller bearings for ultra-straight and smooth motion
