Long Travel Linear Motor Stage – 32“ Travel, Nanometer Resolution
PI (Physik Instrumente) LP Posted 04/02/2019
The new linear translation stage from PI is engineered for industrial applications with high demands on dynamics, precision, smooth scan motion, short settling times, and low tracking error.
Auburn, MA – PI is offering the new V-417.336025E1 long travel linear motor stage, providing 32 inches of travel (813mm). The direct drive stage achieves high velocities to 79”/sec (2m/sec) based on a direct drive ironless linear servo motor. High accuracy, repeatability, and functionality are guaranteed by an integrated absolute-measuring linear position encoder featuring 1 nm sensor resolution.
High performance connectors, a cable drag chain, and special protection from contamination provide the required toughness and reliability in 24/7 industrial automation applications.
The zero-wear, non-contact nature of electrodynamic linear motors integrated in the linear motor stages along with recirculating ball bearings (high load capacity without cage migration issues) and frictionless, non-contact linear encoders is what sets these stages apart from conventional motorized stages. For even higher accuracy requirements and virtually unlimited lifetime, stages with friction and wear-free air bearing guidance are also available from PI.
Applications for the Linear Motor Stage
The V-417 long travel motorized positioning stages see use in pick and place applications, optics, photonics and micro-electronics test and assembly, semiconductor test and inspection, bio-technology, DNA sequencing, 3D printing and laser processing and machining.
Motion Controllers for Linear and Rotary Stages
Several single and multi-channel controller options are available. For highest performance, ACS industrial motion controllers are recommended. The motion controller & drive unit provides sinusoidal currents for the 3 phases of the linear motor to guarantee uniform force delivery and excellent velocity stability for extended travel ranges. Short travel linear stages with single phase (voice coil) motors can also be operated by the motion controllers.
