The V-52x series of voice-coil-driven linear stages come in 3 sizes and provide high-dynamics over travel ranges of 5mm, 10mm, and 20mm. Applications include optics scanning, fiber alignment, biotechnology, and laser technology. These compact linear scanning stages achieve significantly higher dynamics and speed than conventional screw-type positioners with stepper and servo motors; scanning frequencies of several 10Hz with velocities up to 250mm/sec can be achieved with the recommended C-413 compact controller. The design uses no moving cables and the frictionless voice-coil drive is not subject to wear & tear and generates no particles.
The V-408 features high load capacity precision crossed roller elements with anti-creep cage assist, preventing roller creep, and a zero-wear, non-contact linear motor – ideal prerequisites for long lifetime in high duty cycle industrial applications. The high-force linear motor achieves velocities up to 0.7m/sec. An integrated optical linear encoder provides 10 nanometers resolution. The stage achieves 20nm minimum incremental motion and excellent geometric performance with 4µm straightness and flatness.
The V-508 provides absolute measuring encoders and longer travel ranges to 170mm.
Wear and Friction Free Bearings, No Particle Generation
Flexures and air bearings provide friction free and wear free precision guidance.
The A-141 miniature Air Bearing Stage is equipped with a 3-phase motor, fully preloaded air bearings, and an integral high-resolution optical linear encoder. A locking design provides the ultimate in position stability. This stage offers ultra-precision in a very compact package.
The V-900KPIC is an example of a miniaturized voice-coil driven stage with flexure guidance. Low inertia allows for very high dynamics. Closed and open-loop operation is possible, and the integrated 100 nanometer linear encoder provides reliable position control and repeatable accuracy. PI's C-413 motion controller features 10kHz servo update rate.
