Voice Coil + Air Bearing = Highly Precise Dynamic Motion

PI (Physik Instrumente) LP

The PIglide A-131 Voice-Coil-Driven Air Bearing Stage with 1kg payload running at 5 Hz and 8Hz, respectively. Sine scanning is common in the optics world, where actuators like galvanometers oscillate mirrors and lenses in rotary fashion. For applications where true linear motion is required a different technology must be used. Air Bearings provide frictionless motion with exceptional guiding precision. Voice Coils provide high dynamics at travel ranges to 1
