Linear motion system brings modularity to small-space applications

Thomson Industries has introduced a new family of compact linear systems that makes it easier for motion designers to implement complex applications in small spaces. Designers needing thrust and bearing support in a single, compact unit now have flexibility to build such applications.

“As demand for smaller-scale applications grows, so does the challenge of packing high functionality into a smaller footprint,” said Hans Dahlen, product line manager for linear motion systems at Thomson. “Our new family of compact linear motion systems equips designers to meet those challenges by assembling world-renowned Thomson linear motion components, with the added option of real-time collaboration with a Thomson engineer.”

In building a compact linear system from Thomson, a designer can configure a unit or combination of units from a wide variety of components based on their specific application details. Components include:

• Integrated stepper motors
• Lead screws
• Profile rail linear guides
• 60 Case LinearRace shafting
• Linear Ball Bushing bearings
• End blocks

Many features can be customised, including screw diameters and leads, mounting holes and mounting configurations.

To enable engineers to take maximum advantage of such flexibility, Thomson offers a new 3D modelling tool that optimises their solution by revealing design trade-offs in real time. The tool, in collaboration with a Thomson engineer, guides the designer in tailoring motor size, stroke length, and other variables to function most effectively within given load and space parameters.

The resulting designs go directly to the Thomson product CAD system, where the information is used to produce the prototype sent for testing. Because of such close user involvement during the design process, the number of design iterations is reduced, which, in turn, decreases the likelihood of mistakes being made.

Thomson says its compact linear systems are appropriate for applications requiring high-accuracy linear axes in confined spaces, such as 3D printers, microscope stage managers, medical pipetting systems and semiconductor manufacturing. They are available with NEMA motor sizes between 14 and 23; stroke lengths of up to 1000 mm; and load capacities up to 9300 Newtons.
