Auburn, MA – PI, a premium producer of nanopositioning tools and air bearing levels, has developed a high-precision, maglev-based expertise demonstrator. Magnetic levitation is a frictionless movement expertise that employs magnetic fields to levitate and propel objects. MagLev expertise is utilized in numerous purposes, finest recognized from high-speed trains and magnetic bearings, and has nice advantages in precision movement management and nanopositioning purposes.
The fundamental precept of magnetic levitation is that like magnetic poles repel one another. To attain magnetic levitation in its simplest kind, two magnets are used; one magnet is positioned within the object that must be levitated, and the opposite magnet is positioned beneath it.
To make this precept helpful for nanopositioning and precision movement management, for instance in linear translation levels, the magnets within the base should be electrically controllable coils and it takes greater than only a pair to additionally management lateral movement, vertical movement and pitch, yaw, and roll. A high-resolution place sensing system can be required for suggestions to the movement controller. Since no mechanical bearings limit the movement of the linear stage platform, all six levels of freedom can be found to appropriate any bearing insufficiencies, with a strong multi-axis controller.
Purposes of maglev nanopositioning techniques might be present in semiconductor check and metrology, photonics, optics and high-resolution microscopy to call just a few. Benefits are absence of particle era (cleanroom appropriate) zero-wear and 0 upkeep, multi-dimensional controllable movement in a compact bundle and just about limitless service life. In distinction to air bearing levels, no provide of compressed air is required.
PI has been investing in analysis on magnetic levitation for nanopositioning purposes and can work with clients to maneuver the expertise ahead collectively. A expertise demonstrator is on the market at PI’s Silicon Valley tech middle.
PI is a worldwide chief in photonics alignment, precision movement management, nanopositioning levels, and automation sub-systems. Applied sciences embody hexapods, magnetic drives, air bearings, and piezo drives. The corporate was based 5 a long time in the past and as we speak employs greater than 1,500 folks in additional than 20 areas around the globe with manufacturing websites in USA, Europe, and Asia. PI’s clients are leaders in high-tech industries and analysis institutes in fields akin to photonics, life-sciences, semiconductors, and aerospace.
