A new weld head from Emhart Fastening Teknologies features a linear-motor drive that precisely times and controls lift heights, plunge velocity, and depth penetration of each attachment during welding ...

Linear motion is central to many moving machines, and the direct-drive nature of linear motors can simplify overall machine design in these applications. Other benefits include improved stiffness, ...

Ok, I lied. This is more of a "do my math" request than a question. I'm working on a project that requires lifting a 10 lb load vertically using a lead screw (threaded shaft) and then lowering it ...
