The A-131 is a voice coil linear stage with air bearings for high-speed, high-precision positioning in cleanroom environments. It offers 25 mm travel, 40 m/s² acceleration, and 1000 mm/s maximum velocity. The stage uses an incremental linear encoder with 20 µm signal period and achieves typ. ±0.25 µm positioning accuracy when calibrated. It operates at 48 V nominal voltage with 70.4 N peak force and a force constant of 6.9 N/A. Mounted on hardcoat aluminum with stainless steel hardware, it has a total mass of 3600 g and supports up to 30 N push force. Air-bearing operation requires clean, dry, oil-free air at 520-585 kPa with ISO 8573-1 class 1 quality and max. 28 L/min air consumption. It includes a D-sub 9W4 power connector and D-sub 15 sensor connector with 0.45 m cables. Recommended controllers are the A-81x and A-82x series.
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.
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.
High-speed scanning, applications in manufacturing.
Thanks to the friction-free motion, no particles are formed, which makes PIglide stages ideal for cleanroom applications.
