en.Wedoany.com Reported - PI's new V-700 series mechanical bearing XY stage is designed for applications requiring high precision without the need for air bearings. Among them, the V-783 high-precision XY linear motor stage is one of the most competitive thin XY positioning systems in the series. Designed and manufactured in the US, this stage features a 360x360mm aperture, enabling long travel, nanometer-level positioning, and smooth high-speed scanning. It is suitable for semiconductor inspection, photonics alignment, metrology, imaging, biotechnology, laser micromachining, precision assembly, microscopy, and advanced automation systems.
The V-783 stage offers over 12 inches (±155mm) of travel on each axis, utilizing a compact integrated XY structure that is thinner and stiffer than traditional solutions composed of independent direct-drive linear stages. The large open aperture supports transmitted light applications, while the direct-drive, ironless brushless linear motors eliminate backlash and transmission chain gaps, enabling smooth and highly repeatable multi-axis motion. Key specifications include: 12.2x12.2 inch (310×310mm) travel, compatible with 300mm wafers; 360x360mm aperture for transmitted light; 1 nm encoder resolution, with optional incremental or absolute encoders; maximum speed of 1 m/s and acceleration of 10 m/s²; ±0.07 µm bidirectional repeatability and ±0.17 µm positioning accuracy; 0.75 µm straightness and flatness; integrated XY design supporting a 50 kg load with high stiffness. The absolute encoder option provides position information immediately upon power-up without requiring a homing procedure, helping to improve equipment availability.
This stage can be paired with PI's ACS-based A-800 series motion controller to form a high-performance motion system, supporting synchronized multi-axis operation, EtherCAT network connectivity, and advanced servo control capabilities. The V-783 stage provides OEMs and system integrators with a robust positioning platform that combines direct-drive performance, nanometer-resolution feedback, high geometric accuracy, and long travel in a compact design, suitable for precision inspection, manufacturing, and automation applications.
