May 17, 2018– The reference-class linear stages family, L-417 and V-417 from PI (Physik Instrumente), are available in ballscrew and linear motor configurations. Applications for both include high demands on dynamics, precision, smooth scan motion, short settling times, and low tracking error, such as laser cutting, scanning, digital printing, electronics assembly and inspection, AOI (Automatic Optical Inspection), automation, and flat panel manufacturing.
The L-417 ball screw model accommodates a load capacity of 450N on its 166m width frame with a travel up to 813mm. With a synchronous servo motor, it uses rotary and linear encoders, and can be re-lubricated without disassembly. A cover strip on the side and the purge air connection prevent contamination of the working components by particles. An optional holding brake allows an increase in its usability as a Z axis stage.
With a similar load capacity, width and travel range, the V-417 is powered by an ironless linear motor, and linear encoder. The 3-phase magnetic direct drive transmits a drive force of 87N to the motion platform directly, without friction. Also like its ball screw family member, the V-417 has a cover strip on the side and the purge air connection prevents contamination of the working components by particles.
