Linear stage V-508 series

linear motor-drivencrossed rollerprecision

• Minimum incremental linear motion to 1 nm • Choice of iron core and ironless 3-phase linear motors The V-508 family of high-precision linear motor stages provides high speed and accuracy in a very compact, low-profile package. These closed-loop, motorized nanopositioning stages are well suited for high-dynamics 24/7 industrial automation applications, based on a concept that was designed with reliability in mind – high performance bearings, zero-friction linear motors, non-contact optical position sensors, and an FEA (finite element analysis) optimized body for stiffness and thermal stability. Frictionless Direct Drive Linear Motors – Very High Resolution Driven by in-house developed, frictionless, brushless 3-phase linear motors and controlled by direct-measuring linear encoders, the V-508 series linear translation stages can provide high resolution linear motion with minimum increments down to 1 nanometer, for the highest performance variants. Direct Metrology Encoders with Sub-nm Sensitivity There is a choice of cost-efficient incremental encoders, PIOne metrology-class interferometric encoders and absolute measuring encoders (no referencing on power up required). Since the linear position of the stage is measured directly at the moving platform against the stationary base, without contact (direct metrology), backlash, mechanical play, or deformation in the drive train as common with motor / leadscrew combinations have no influence on position accuracy.
