High-Precision Linear Motor Stage with Absolute Encoder and Ironless Motor

Motion and precision positioning systems expert PI (Physik Instrumente) has released a new member of the PIMag® family of precision positioning stages with magnetic direct drives. The compact ultra-precise V-551 motorized linear translation stage debuted at Laser World of Photonics, held in Munich, Germany.

V-551 comes equipped with an integrated absolute-measuring, 2nm resolution encoder - no more wasted time for referencing required. High velocity to 500mm/sec and quick acceleration is provided by a newly developed ironless magnetic linear motor, resulting in high accuracy and smooth motion. Precision crossed roller bearings with anti-creep cage assist guarantee excellent guiding accuracy (1 µm straightness / flatness per 100 mm).

Ironless non-cogging linear motors provide very smooth motion, and a high dynamic velocity range along with rapid acceleration. They are ideal for applications where high or extremely constant velocity is required, such as in optics inspection, metrology, photonics, interferometry, and semiconductor test equipment. The frictionless, zero-wear motor drives are also popular in fast automation applications, where reliability and maximum uptime are crucial. The V-551 is available with several travel ranges up to 230 mm.
