Novel bi-phase piezo motor allows correct linear movement in an especially compact bundle, new from PI.
PI’s B-421 miniaturized piezo phases present 10 nm positioning decision in an especially compact bundle. X, XY, XZ and XYZ combos can be found, with journey ranges from 13 to 32 mm. Picture Credit score: PI (Physik Instrumente) LP
PIa worldwide chief in nanopositioning, precision movement management techniques, and air bearing expertise, introduces the revolutionary B-421 BIX nanopositioning phases — compact, high-precision linear positioning techniques designed for purposes requiring dependable and correct movement in extraordinarily space-constrained environments.
Geared up with built-in linear encoders with 6 nanometer place decision and superior dual-phase piezo inertia motors, BIX phases ship clean, backlash-free efficiency with glorious repeatability, and a minimal incremental movement of simply 0.01 microns per step.
Not like typical stick-slip motor phases, the BIX collection makes use of two miniature piezo stacks, manufactured in-house by PI’s piezo ceramics division, PI Ceramic. This superior bi-phase inertia drive expertise delivers increased drive and holding forces, elevated velocity, and prolonged operational lifetime in comparison with conventional stick-slip options.
XY, XZ, and XYZ Multi-axis Stage Combos
The BIX linear stage design helps multi-axis configurations and affords journey ranges of as much as 32 mm, making these miniature nanopositioning phases supreme for high-precision movement purposes, corresponding to bio-nanotechnology, super-resolution microscopy, metrology, life sciences, spectroscopy, micro-assembly, photonics, semiconductor manufacturing, and interferometry.
Stick-Slip Drive Know-how Background
Stick-slip inertia motors function on a precept much like the traditional tablecloth trick, utilizing piezoelectric actuators pushed by a modified sawtooth voltage sign from devoted management electronics. Throughout the gradual growth part, the actuator steadily strikes a runner ahead. When the actuator contracts quickly — inside microseconds — the runner’s inertia prevents it from following, leading to internet ahead movement. A symmetrical motor configuration ensures constant efficiency in each ahead and reverse instructions.
Piezo Motor Controller and Software program
The E-881 BIX piezo motor controller is designed for high-performance management of low-voltage, two-phase stick-slip piezo motors, enabling clean, exact movement with nanometer decision. It options built-in encoder suggestions, digital servo management electronics, and is suitable with PI’s PIMikroMove® software program. Communication is supported by way of USB and TCP/IP interfaces. Extra options embrace programmable digital outputs, and a built-in information recorder. The controller comes with an in depth set of drivers, e.g., to be used with C, C++, C#, NI LabVIEW, MATLAB, Python, and a digital startup emulator for testing with out {hardware}.
