PI (Physik Instrumente) L.P. PIMag® Precision Linear Stage V-551

Travel ranges to 230 mm Velocity up to 0.5 m/s Absolute encoder with 1 nm resolution Excellent guiding accuracy Compact design with 160 mm width Reference-class linear stage Thanks to the smooth-running precision linear guides with crossed roller bearings, the linear positioning stage is particularly suitable for scanning applications with constant velocity. The anti-creep system reliably prevents cage creep. The guides have high load capacity and high precision under all operating conditions. PIMag® magnetic direct drive The stage has an ironless magnetic direct drive, which makes high velocities and acceleration possible. Due to the friction-free drive and the sine-commutated control by a motion controller from PI, high position resolution is achieved. The push and pull force is freely adjustable. Direct-measuring absolute encoder The absolute encoder supplies explicit position information that enables immediate determination of the position. This means that referencing is not required during switch-on, which increases efficiency and safety during operation. Position measuring takes place directly at the motion platform with the highest accuracy so that nonlinearity, mechanical play or elastic deformation have no influence on position measuring. Fields of application Industry and research. Automation, measuring technology, photonics and precision scanning in semiconductor or flat panel display manufacturing
