Linear motor stage offers long travel, nanometer resolution

The new V-417.336025E1 long travel linear motor stage from PI (Physik Instrumente) features travel length of 32 in. (813 mm). The direct-drive stage achieves high velocities to 79 in./sec (2 m/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.

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.

Several single and multi-channel controller options are available. For highest performance, ACS industrial motion controllers are recommended. The motion controller and 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.
