Notes:

· All trajectory data based on axis uniformly supported over full length on precision mounting surface with vibration isolation.

· Payload capacities are recommended values to achieve maximum lifetime in the worst-case scenario featuring maximum dynamic operation and off-center loading.

· Force, acceleration and speed performance are based on operations with NUTEC ELECTRONIC controls.

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. The linear motor and other components in LINEAX can be prepared for vacuum compatibility.

LINEAX-6 all structural materials are high-strength aluminum alloys, all surfaces are precision machined, hard coat-anodize finished in light gray. One or two precision re-circulating linear ball bearings are guided by 2 integrally pre-loaded ball tracks on each rail. The guide system requires only standard lubrication service.

LINEAX-6 stages have a compact envelope with no motor overhang. Linear motor, encoder and cables are internal with cables terminating in connectors mounted to the stage's base.

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. When the application is for precision positioning, the temperature rise has an undesirable effect of influencing accuracy because of thermal induced distortion, either short term or for the duration of operation.
