November 3, 2017 – PI further expands its PIMag series of high dynamics linear motor stages with a family of 18, the V-508 - a series of linear positioning stages with high force 3-phase linear motors and crossed roller guides.
The V-508 family of linear motor stages is offered with 80mm, 170mm, and 250mm travel range. Two motor options are available – ironless for high resolution and smooth motion, and iron-core for high force, acceleration, and velocity up to 1m/sec.
Mechanically, the V-508 series features high load precision crossed roller bearings with anti-creep cage assist, preventing roller creep – together with the non-contact linear motor.
A variety of incremental and absolute measuring linear encoders are available, from 0.2 nanometer resolution to 78 nanometers 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.
They are designed for scanning applications or automation tasks where repetitive fast start/stop motion with 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.
