Auburn, MA – World precision movement management and nanopositioning trade chief PI introduces a brand new excessive dynamics linear motor stage household, the V-574 – a brand new sequence of linear positioning phases with wonderful guiding precision and frictionless 3-phase linear motors.
Glorious Guiding Precision – Geometric Efficiency
Geared up with high-precision crossed-roller bearings put in in a proprietary course of, these phases obtain wonderful geometric efficiency: the 130mm variant, for instance, options 1.2µm straightness and flatness over the complete journey vary, together with pitch and yaw of solely 45 and 40µrad, respectively.
Excessive Velocity – Excessive Responsibility Cycle – 3 Journey Ranges
The V-574 linear motor phases are provided with 60mm, 130mm, and 230mm journey vary.
Three-phase ironless, cog-free linear motors switch their drive straight and friction-free to the movement platform eliminating backlash and play that may happen with screw-driven phases. The V-574 phases obtain velocities as much as 1m/sec and 1g acceleration, whereas the brushless motors are maintenance-free, guaranteeing longevity in demanding 24/7 operations.
Selection of Three Optical Encoders for Incremental and Absolute Measuring
Three encoder selections can be found, two sine/cosine encoders for conventional movement controllers and an absolute encoder with BiSS-C switch protocol. Absolutely the encoder achieves 1nm decision and transmits the present stage place to the controller instantly after energy up – no referencing required and no risk to lose encoder counts in electrically noisy environments.
What’s the Advantage of Linear Motors?
Mechanically, the V-574 sequence options ironless non-cogging linear motors which permit for very clean movement, and a excessive dynamic velocity vary together with fast acceleration. They are perfect for functions the place excessive or extraordinarily fixed velocity is required, akin to in optics inspection, metrology, photonics, interferometry, and semiconductor take a look at gear. The frictionless, zero-wear motor drives are additionally widespread in quick automation functions, the place reliability and most uptime are essential.
