Global precision motion control and nanopositioning industry leader PI has expanded its portfolio with a new high dynamics linear motor stage family, the V-573 – a new series of linear positioning stages with excellent guiding precision and frictionless 3-phase linear motors.
Specifications
- 160/260/360 mm travel
- 1 nm absolute encoder resolution
- 80 nm bidirectional repeatability
- Straightness/flatness to 1 µm
- 500 mm/sec max. velocity
- 1 g acceleration
- 140 N push/pull force
With 80 nm bidirectional repeatability, 1 g acceleration, and 500 mm/s velocity, the V-573 family combines precision and speed for demanding production environments. Designed for XY configurations, the stages integrate seamlessly with PI’s ACS-based EtherCAT motion controllers, leveraging advanced algorithms for optimal system performance.
The advanced stage design provides for excellent straightness and flatness values as low as 1 µm. Crossed roller bearings ensure high stiffness, smooth running, and extended lifetime. Their line-contact design minimizes friction, improves accuracy, and supports higher loads, with an anti-creep mechanism for enhanced reliability.
Driven by non-cogging, 3-phase direct-drive linear motors, the stages deliver maintenance-free performance with smooth motion at high velocities and accelerations. Direct force transmission together with direct-measuring linear encoders eliminates backlash and play, while improving accuracy and bidirectional repeatability.
The V-573 is available with incremental or absolute encoders. Absolute encoder models offer 1 nm resolution and immediate position feedback on power-up, eliminating referencing moves for efficient, safe startup.
