LINEAX-10- Precision Stage

Description

  • Precision Stage
  • Environmentally hardened.
  • Precision guiding system provides stable trajectory across long travel and at high speeds.
  • Powerful linear motors are used in the Lineax series; provide driving force to position high payloads.
  • High-resolution linear encoders are incorporated to allow precise position feedback and closed loop servo.

Lineax-10 Precision Stage Features & Benefits

Direct drive linear motors for stage positioning exhibit advantages over conventional screw driven stages. Lacking the elastic deformation seen in screw drive systems allows direct drive systems to produce more compliant positioning trajectories, faster settling times, higher repeatability and faster servo response. Free of rotating inertia, much faster acceleration and higher velocities are achievable. Wear of rotating components is eliminated increasing reliability, uptime, and extending servicing intervals each of these contributes to reducing cost of ownership. The direct drive linear motor with the high-resolution encoder allows precise velocity regulation. The linear motor and other components in Lineax can be prepared for vacuum compatibility.

Lineax-10 precision stages-  all structural materials are high-strength aluminum alloys, all surfaces are precision machined, finished with hard coat-anodize in light gray. Two precision square type guide rails with integrally pre-loaded, re-circulating, linear bearings are guided by 6 ball tracks on each rail. The guide system requires only standard lubrication service.

Lineax-10- precision linear stages utilizes a self-managing internal cable loop system featuring ultra-high flex cables for linear motor, encoder’s, and sensors, all terminated at a single DB-type connector.

Applications

A linear motor driven stage lacks the mechanical gearing advantage of a screw driven stage and therefore is more application specific. Loading directly affects maximum acceleration available, in accord with Newton’s relationship F=(m*a). The ability of a stage to reach a specific maximum speed may affect the cycle time or system throughput.

Linear motors generate substantial peak force when supplied the necessary current by the servo-drive. The higher the current, the more resistive heating experienced by the copper magnet coils. Resulting in rising motor temperature. When the application is for high precision positioning, temperature rise has the undesirable effect of influencing accuracy via thermal induced dimensional distortion. Careful motor sizing, proper heat sinking and attention to drive current modulation can be used to optimize performance for either short term or for a life time duration of high precision operations.
