PI now offers a new reference class XY stage in its PIMag series of high-dynamics linear motor stages with the V-731, equipped with incremental linear encoders for direct position measurement and 3-phase electromagnetic linear motors. Fields of application include micro-assembly, biotechnology, precision laser machining, optics, lens testing, and photonics alignment.
The proprietary PIMag stages do not require mechanical components in the drivetrain as the force is transmitted directly by magnetic forces to the motion platform, without friction and zero-wear on the drive. The ironless, non-cogging linear motors provide very smooth motion, and a high dynamic velocity range along with rapid acceleration. They are suitable for applications where high or very constant velocity is required and reliability and maximum uptime are crucial.

The V-731 stage is equipped with integrated linear encoders providing 10nm resolution. Precision crossed roller bearings with anti-creep cage assist guarantee excellent repeatability to 100 nanometers from this compact low-profile stage, measuring only 310×310×80mm.
