Motorised linear translation stage is compact & precise

 

Physik Instrumente has released a new member of the PIMag family of precision positioning stages with magnetic direct drives. The compact and ultra-precise V-551 motorised linear translation stage debuted at Laser World of Photonics, held in Munich, Germany last month.

The V-551 comes equipped with an integrated absolute-measuring, 2nm resolution encoder – meaning that no more time is wasted referencing. 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 (1µm straightness / flatness per 100mm).

Ironless non-cogging linear motors provide very smooth motion, and a high dynamic velocity range along with rapid acceleration. They are suited 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 230mm.

Together with PI’s compact C-891 controller, the V-551 stage forms a flexible and affordable positioning system. A lower cost stage variant that swaps the absolute encoder with a high-resolution incremental encoder is also available, as well as custom designs for OEMs with higher resolution, peak force, and different travel ranges.

Examples of suitable applications include industry and research, such as optics inspection, metrology, photonics, medical engineering and precision scanning in semiconductor or flat panel display manufacturing.
