Precision linear stage

Positioning systems that meet the high demands on precision and dynamics are required for a large number of applications in automation technology; at the same time, purchase costs often play a decisive role. PI (Physik Instrumente) has added the V-408 PIMag linear stage to its portfolio, the best solution for simple and price-sensitive automation tasks.

The compactly designed V-408 has a width of 80 mm and height of 25 mm, and is suitable for travel ranges to 25 or 50 mm, and velocities to 1.5 m/s and this allows high throughput rates. The minimum incremental motion is 20 nm with a bidirectional repeatability of +/-0.1 µm. If required, it is also possible to combine the linear stages to multi-axis systems.

Three-phase linear motors are the driving force of the linear stages. The iron core maximizes the magnetic forces in a small installation space und ensures high acceleration as well as the thermal stability of the drive. Crossed roller bearings with anti-creep system guarantee high guiding accuracy and load capacity. Position detection directly at the motion platform makes sure that positioning is not influenced by nonlinearity, mechanical play or elastic deformation.
