Abstract in Undetermined
The demands for energy efficent heating solutions for the manufacturing industry can be met by a new induction heating platform, presented in this article. A new concept and technology to design and manufacture induction heating units is explained, evaluated and tested with successful results. The so called Greenheat technology relies on inductors built on Litz wiring moulded in soft magnetic composite; a flux conducting material produced using rotational casting methods. The aim of the article is to present and verify a hyphotesis of greatly improved induction heating results when modifying a traditional inductor design in four dependent steps. The verification is done using analytic solutions and FEM simulations as well as by experimetal work, clearly showing higher heating efficiency, no requirement for advanced cooling and a higher geometrical flexibility compared to existing heating solutions.
