Sep 2017AUBURN, Mass., Sept. 21, 2017 — Physik Instrumente LP has announced the V-408 linear motor stage with magnetic direct drive.

The V-408 stage is equipped with an incremental linear encoder for direct position measurement and a high-force three-phase linear motor drive. The system features high-load capacity precision crossed roller elements with anti-creep cage assist, preventing roller creep, and a zero-wear, noncontact linear motor, which are ideal for long lifetime in high-duty-cycle industrial applications.

The high-force linear motor achieves velocities up to 1.5 m/s. An integrated optical linear encoder provides 10-nm resolution. The stage achieves 20-nm minimum incremental motion and high geometric performance with 4-µm straightness and flatness. The V-408 is designed to keep cost of ownership and operation at a minimum. Two models are offered with 25- and 50-mm travel range. Integration is facilitated by the compact dimensions with a low profile of 25 mm. The 1-in. travel model features a square footprint of 8 × 80-mm while the 2-in. travel model is only 25 mm longer.More products
