PI’s ultra-precise linear motor stages are well-suited for industry and research. Applications include metrology, testing, positioning, scanning, precision automation, micro-assembly, biotechnology, delay-lines, laser beam control, optics, lens testing, and photonics alignment.
Motion and nanopositioning industry leader PI further expands its PIMag® series of high dynamics linear motor stages with a family of 18, the V-508 – a new series of compact linear positioning stages with high force 3-phase linear motors and crossed roller guides.
High Velocity – High Duty Cycle – 3 Travel Ranges
The V-508 family of linear motor stages is offered with 80 mm, 170 mm, and 250 mm travel ranges. Two motor options are available – ironless for highest resolution and smoothest motion, and iron-core for highest force, acceleration, and velocity up to 1 m/sec.
Mechanically, the V-508 series features high load precision crossed roller bearings with anti-creep cage assist, preventing roller creep – ideal prerequisites for long lifetime in high duty cycle industrial applications, together with the zero-wear, non-contact linear motor.
Encoder Options – Incremental and Absolute Measuring
A variety of incremental and absolute measuring linear encoders are available, from 0.2 nanometer resolution to 78 nanometer resolution. Absolute encoders provide the stage position to the controller immediately after power up – no referencing required and no possibility to lose encoder counts in electrically noisy environments.
What’s the Benefit of Linear Motors?
Linear motors provide very smooth motion, and a high dynamic velocity range along with rapid acceleration because they provide motion directly without the need for additional mechanical components, such as drive screws and gearboxes that add friction, vibration, and noise. They are ideal for scanning applications or automation tasks where repetitive, fast start/stop motion with high precision is required and where reliability and maximum uptime are crucial. In addition to electromagnetic 3-phase and voice-coil linear motors, PI also provides several types of electro-ceramic linear motors.
Controllers and Software
Several types of controllers, along with a plethora of software tools, drivers, and example programs are available from PI and ACS motion control.

Wow, this was a fascinating read, I had no idea that motors had enhances so much in this kind of field. It seems to me that, by making motors that can handle automation tasks better you could really help out a lot of industries. I would be fascinated to learn more about how these motors work and what they could be applied to.
