Motor Testing Equipment

Motors and condition monitoring explained

Siemens will be showcasing its latest low- and medium-voltage motors and predictive condition monitoring technology at the EASA Convention. Technology experts will be on hand to give demonstrations and to explain how the products “make life better for users.” What Siemens characterizes as one of the most robust standard TEFC medium-voltage motors in the industry, Advantage Series, will be on display. Representatives from the Norwood, Ohio, motor manufacturing facility will also explain to attendees about its extensive direct load testing capabilities. Motor design concepts will be demonstrated on a new 3D explorer application. A gift and a link for an online version of the app will be made available to select visitors.

Explaining the benefits of laser cladding

Alabama Laser of Munford, Ala., will be showing its laser cladding capabilities at Booth 1123. Laser cladding, the company explains, is a process used to deposit a layer of material onto a surface to repair shafts or keyways on electric motors. In comparison to heat inducing technologies (conventional plasma weld overlay, MIG, TIG, or Sub Arc welding), laser cladding uses low heat that’s said not to affect the concentricity or cause warpage of the shaft. After being clad, the repaired area may then be post-machined back to print specification, according to Alabama Laser. Unlike metalizing processes that produce a mechanical bond that can flake off, the durable clad produced with lasers is a metallurgical bond that will not flake off during assembly or in process, the company adds. Laser cladding also allows alloys to be added to strategic areas on the shaft to eliminate problems such as wear and corrosion.
