High-Performance Linear Stage for Automation features Frictionless Motor and Excellent Guiding Precision
PI’s new linear motor stage was designed for test, assembly and automation applications where extreme guiding precision and accuracy are key.
Auburn, MA - Global precision motion control and nanopositioning industry leader PI introduces a new high dynamics linear motor stage family, the V-574 - a new series of linear positioning stages with excellent guiding precision and frictionless 3-phase linear motors.
Excellent Guiding Precision - Geometric Performance
Equipped with high-precision crossed-roller bearings installed in a proprietary process, these stages achieve excellent geometric performance: the 130mm variant, for example, features 1.2µm straightness and flatness over the full travel range, along with pitch and yaw of only 45 and 40µrad, respectively.
High Velocity - High Duty Cycle - 3 Travel Ranges
The V-574 linear motor stages are offered with 60mm, 130mm, and 230mm travel range.
Three-phase ironless, cog-free linear motors transfer their force directly and friction-free to the motion platform eliminating backlash and play that can occur with screw-driven stages. The V-574 stages achieve velocities up to 1m/sec and 1g acceleration, while the brushless motors are maintenance-free, ensuring longevity in demanding 24/7 operations.
Choice of Three Optical Encoders for Incremental and Absolute Measuring
Three encoder choices are available, two sine/cosine encoders for traditional motion controllers and an absolute encoder with BiSS-C transfer protocol. The absolute encoder achieves 1nm resolution and transmits the current stage position to the controller immediately after power up - no referencing required and no possibility to lose encoder counts in electrically noisy environments.
What's the Benefit of Linear Motors?
Mechanically, the V-574 series features ironless non-cogging linear motors which allow for 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.

Featured Product
3D Vision: Ensenso B now also available as a mono version!
This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
