LINEAX-6- Linear Motor Driven Stage

Description

  • Environmentally hardened.
  • Precision guide system provides stable trajectory across long travel and at high speeds.
  • Powerful linear motors are used in the Lineax series.
  • High-resolution linear encoders are incorporated to allow precise position feedback and closed loop digital servo control.

Lineax-6 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.

Lineax-6 all structural materials are high-strength aluminum alloys, all surfaces are precision machined, hard coat-anodize finished. Two precision re-circulating linear ball bearings are guided by 2 integrally pre-loaded ball tracks on each rail. The guide system has extended 5 year intervals only for lubrication service.

Lineax-6 Stages have a compact envelope with no motor overhang. Motor and encoder cables are routed in an external cable loop for long life and serviceability.  The connection port is at the stage end with axial bulkhead exit.

Lineax-6 is an outstanding precision linear motor positioning stage. Well suited for applications in the semiconductor, instrumentation, fiber-optic, biomedical, laser and micro-machining industries. Special finishes like Teflon impregnated hard-coat, non-anodized, and electro less Nickel can be furnished to accommodate specific application environments. Stainless steel components are made from polished material.

Applications

A linear motor driven stage lacks the mechanical gearing advantage of a screw driven stage and therefore is more application specific. The payload directly affects the acceleration rate according to the F=m•a relationship and the ability of the stage to reach a specific speed, which may affect the cycle time or throughput.

The linear motor generates a substantial peak force when supplied the necessary current by the servo drive. The higher the current, the more heating experiences the copper coil, rising motor temperature. The LX-6 is built with an ironcore coil assembly with excellent thermal management capability for robust application environments.
