PI (Physik Instrumente) L.P. A-131 Voice Coil Positioner with Air Bearings A-131

Product overview The PIglide stage with air bearing and voice coil drive offers high velocity and acceleration in a compact package. The contactless components of the motion platform ensure the highest performance, quality, and lifetime. Accessories and options PIglide filter and air preparation kits Single and multi-axis motion controller Voice Coil Drive Technology Voice coil drives consist of 2 essential components: A permanent magnet and a coil that is located in the air gap of the magnetic field. When current flows through the coil, it moves in the magnetic field of the permanent magnet. The direction of motion depends on the polarity. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications, which require high dynamics and high velocities at limited travel ranges. High scan frequencies and precision positioning are also possible with these drives, because they are free of the effects of hysteresis. Application fields High-speed scanning, applications in manufacturing. Thanks to the friction-free motion, no particles are formed, which makes PIglide stages ideal for cleanroom applications.
