Auburn, MA – PI’s new household of direct-drive rotation phases are designed for steady 24/7 operations, demanding excessive dynamic and static precision, with decision all the way down to 0.0015µrad, place accuracy of 10µrad, and bidirectional repeatability of 5µrad. The V-622, V-623 and V-625 high-performance rotary phases are geared up with frictionless electromagnetic torque motors and precision ball bearings and complement PI’s widespread A-622, A-623, and A-625 sequence of air bearing spindles. This new rotary stage vary is flexible, permitting mounting and operation in any orientation, an important attribute for quite a few industrial automation functions.

Close to Air Bearing Efficiency
Leveraging PI’s intensive experience in designing ultra-high-precision air bearing rotary tables, the newly developed V-622, V-623, and V-625 mechanical bearing rotary phases goal to ship excellent efficiency by way of journey accuracy, flatness and wobble, and lifelong. These phases are geared up with ultra-precise deep groove ball bearings, preloaded, and lubricated previous to supply, guaranteeing maintenance-free operation all through the rotation phases’ total lifespan.
Sizes and Velocity
The V-62x household comes with desk diameters from 85mm to 200mm. All fashions characteristic a transparent aperture, starting from 15mm to 105mm. Most angular velocity is 20 revolutions per second or 7,200 deg/sec.
Absolute Encoder Choice
A key characteristic of those phases is the selection of encoders, together with absolute and incremental choices. Absolute encoders present specific place info, facilitating exact dedication of every angular place with out the necessity for incremental counting. This characteristic ensures fast availability of place info upon power-up, enhancing operational effectivity and security.
Movement Controllers
For exact management, a spread of movement controllers is accessible, each in single and multi-axis configurations. These EtherCat-compatible controllers use ACS servo and drive modules and might run multi-degree-of-freedom linear and rotary sub-assemblies, that are additionally supplied by PI.
Functions for the Rotary Phases
The V-622, V-623, and V-625 rotary phases discover functions throughout varied fields, together with optics and photonics, pattern inspection, metrology, semiconductor testing and inspection, industrial automation, measuring expertise, precision micro-assembly, and biotechnology.
