PI introduces V-573 linear stages with 3-phase linear motors

PI has introduced the V-573, a new series of linear positioning stages featuring high-precision guidance and frictionless 3-phase linear motors.

With 80nm bidirectional repeatability, 1g acceleration, and 500mm/s velocity, the V-573 family offers precise motion control suited for production environments. Designed for XY configurations, the stages integrate with PI’s ACS-based EtherCAT motion controllers, using advanced algorithms to improve system performance.

The stage design provides straightness and flatness values as low as 1µm. Crossed roller bearings offer stiffness, smooth motion, and long service life. The line-contact design reduces friction, improves accuracy, and supports higher loads, while the anti-creep mechanism increases 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 1nm resolution and immediate position feedback on power-up, eliminating referencing moves for efficient, safe startup.
