AUBURN, MA, Apr 16, 2025 – PI (Physik Instrumente) has introduced the V-625 direct drive rotation stage, a rotary positioning and scanning system intended for applications that require consistent and precise rotary motion.
The V-625 rotary stage combines frictionless, advanced direct-drive motor technology with a clear aperture. It is the best fit for precision motion in metrology, semiconductor inspection, optics test and alignment, aerospace, and industrial automation.
Absolute-Measuring High-Resolution Encoder Option
A key feature of the V-625 rotation stage is its direct and absolute measuring precision encoder, which provides sensor resolution down to 0.0015 µrad. Absolute encoders provide explicit position information, allowing each angular position to be determined without incremental counting. This feature makes position data available at power-up, improving operational efficiency and safety.
Designed for a New Level of Precision and Performance
Leveraging the PI USA design team’s experience with precision air bearing rotary tables, the V-625 mechanical bearing rotary stage is designed to provide travel accuracy, flatness, wobble control, and durability.
Key Features of the V-625 Rotation Stage:
- Bearings with High Load Capacity: 400N (88lbf) vertical load guarantees long service life.
- High Precision & Stability: Sub-microradian resolution, 10µrad calibrated accuracy, and high axial/radial runout accuracy enable ultra-stable and repeatable rotary positioning.
- Large Central Aperture: 100mm, ideal for beam delivery, cable routing, or vertical metrology setups.
- Direct-Drive Technology: Frictionless torque motor design ensures zero backlash, exceptional smoothness, and maintenance-free operation.
- Direct-Measuring Technology: An absolute encoder with 0.0015µrad resolution is directly coupled to the rotating platform, providing precise position information with no backlash and no need to reference on start-up.
- Robust and Versatile Design: Engineered and manufactured in the USA by PI’s local motion control teams, for both industrial and research environments, the V-625 delivers high torque and reliable performance even under demanding conditions.
- Compatible with PI’s direct-drive linear motion stages.
“The V-625 offers the perfect balance of performance, precision, and cost effectiveness,” said Matt Reck, president at PI USA. “With near air bearing precision, it’s optimized for today’s most challenging rotary motion tasks, giving engineers a high-performance rotation stage that integrates easily into complex multi-axis systems.”
