Linear Stages / Linear Stages – High Accuracy Motorized Translation Stages

A wide variety of motorized linear stages are available from PI. The vast array of applications also translates into a vast array of technological options for linear axis. PI adapts the drive, guides, or sensor technology to the application requirements. Travel ranges range from a few millimeters to meters, and for accuracy classes, from nanometers to micrometers.

For many various models, there are vacuum variations. With the aid of adapter brackets or for greater compactness, corresponding Z stages and rotation stages, multi-axis combinations can be made.

Motion controllers can be purchased as benchtop, rack, or small OEM devices. The General Command Set (GCS), which unifies control and programming and is regardless of drive type, is the common element for all of them.

There are available multi-axis systems with motion controllers from ACS for multi-axis industrial applications. This guarantees straightforward integration via Fieldbus interfaces for industrial applications focused on precision and motion.

A positioning tool that provides linear motion with high accuracy and reduced runout errors is known as a precision linear stage, also known as a linear translation stage. For industrial and scientific applications such as semiconductor fabrication, beamline systems, and photonics equipment, motorized linear translation stages with high resolution and motion fidelity are essential.

Linear Translation Stages: Cost-Effective to Ultra-High-Performance

There are many different types of linear stage designs, ranging from inexpensive stepper-motor-driven positioning and indexing tables to closed-loop motorized linear stages with linear encoders for the best positioning accuracy. Nanometer resolution and better are achieved by modern linear encoders. Electromagnetic, direct drive linear motors are advised when the best velocity control, highest performance, and speed are needed. The direct-drive method boosts overall performance and gets rid of losses brought on by friction, wear, and linear motion from rotation.

Direct drive linear translation stages with air bearings are available for the best geometric and positioning performance over extended travel distances.
