Compact Piezo Stages with Novel Bi-Phase Motors Provide 10nm Resolution
Summary
Accurate linear motion in an extremely compact package, new from PI AUBURN, Mass., May 13, 2025 /PRNewswire-PRWeb/ -- PI, a global leader in nanopositioning, precision motion control systems, and air bearing technology, introduces the innovative B-421 BIX nanopositioning stages — compact, high-precision linear positioning systems designed for applications requiring reliable and accurate motion in extremely space-constrained environments. Equipped with integrated linear encoders with 6 nanometer position resolution and advanced dual-phase piezo inertia motors, BIX stages deliver smooth, backlash-free performance with excellent repeatability, and a minimum incremental motion of just 0.01 microns per step. When the actuator contracts rapidly — within microseconds — the runners inertia prevents it from following, resulting in net forward motion. It features integrated encoder feedback, digital servo control electronics, and is compatible with PIs PIMikroMove® software. The controller comes with an extensive set of drivers, e.g., for use with C, C++, C#, NI LabVIEW, MATLAB, Python, and a virtual startup emulator for testing without hardware.
