Customized energy source for perfect induction heating
eldec generators CUSTOM LINE
“Customized” is the key word when it comes to delivering a perfect production solution in plant and machinery manufacture. Each technology is to a large extent individually tailored to the customer's environment, guaranteeing a highly efficient, optimally configured process. Induction heating, especially, is one technology that must be “customized”, because the quality of the procedure depends on a whole range of very specific details in the user's application. The generator, being the energy source, plays an important role in this, as the experts at EMAG subsidiary eldec, based in Dornstetten, Germany, know very well. They have been developing a wide variety of generators for more than 30 years, including many customized models in their CUSTOM LINE. Their approach is to engineer all the resonant-circuit components in conjunction with the control architecture to form a customized product, which provides induction heating with high efficiency, controlled application of energy, and stable processes. In order to make this process successful, close collaboration with the customer is required throughout the entire development process of the generator.
There are many possible application areas for induction hardening technologies. This efficient technique is used in the manufacture of plant and machinery, in the automotive sector, in aerospace, and in tool and die making. In the latter case, it is used to harden precisely those features of the tool or die that carry the greatest load later in the punching or embossing machine. Another typical area of application is the heating of components for a subsequent joining process. The technology is also used in standardized applications like induction brazing and soldering, especially in the energy sector. Its decisive advantage here is precise targeting: The electromagnetic field applied can be adjusted perfectly to the workpiece in terms of its frequency, output, and field characteristics, so only a very precisely defined area is actually heated. This precise application of energy also ensures speed, minimal workpiece distortion, and economical energy consumption. In many respects, however, the result depends on the technology used. Apart from the inductor, it is the generator that attracts the special attention of the developers. The Induction specialists at eldec therefore offers its customers not only the standardized models of the PICO, MICO, and ECO series, but also the tailored products of the CUSTOM LINE. Harry Krötz, head of Electrical Engineering R&D at eldec, explained the situation: “We always adjust the resonant circuit, the inverter, and the inverter control to match the inductor, the required frequency, and the output. We do that even with our more standardized series, with which we can currently cover about 80 percent of applications. With our CUSTOM LINE, however, virtually all the components can be configured in a fully variable way—from general device control to the outputs and interfaces.”
