EDGE-WINDING
Advancing Cooling and Efficiency
With the introduction of the next-generation N CNW reactor and filter series, REO pushes the boundaries of EDGE winding technology. This innovation offers increased effectiveness and reduced weight, providing superior cooling through a single-layer design—especially beneficial when forced cooling is used.
The advanced cooling technology allows for the use of aluminum conductors instead of copper, which, combined with automated production, significantly reduces manufacturing costs.
This technology also lowers weight and component size, while minimizing skin and proximity losses. The EDGE winding is perfect for new semiconductor materials like silicon carbide (SiC) and gallium nitride (GaN), and its reduced winding capacitance enables high-frequency operation.
The near-elimination of insulating materials enhances component lifespan.
Up to 10% reduction in weight
Sven Reimann, Member of the Board of Directors at REO AG, shares: “Edge winding technology is an innovation of our development team, which is constantly researching intensively into the latest technologies and always thinking along new lines. We have recognized the opportunity of the new winding technology and since 2020 have been able to produce in small or large series and offer our customers extremely fast delivery times. What particularly excites me about the N CNW series is the cooling property, which enables alternative materials to be used thanks to the single-layer structure and makes insulating material almost superfluous. On the one hand, the dimensions and weight are reduced, on the other hand, the service life increases and the range of applications is wider than with conventional winding techniques.”

REO: A reliable partner
As one of the world’s leading manufacturers of inductive components, REO specialized early on in the challenge of EMC problems in frequency converter-controlled drive systems. In cooperation with manufacturers of drive systems and mechanical engineering companies, we have innovatively advanced this development over the last four decades. Our EMC solutions are specially tailored to these drive systems. Thanks to our comprehensive vertical integration and expertise in filtering such systems, which is bundled in our own development center, we can offer our customers the best possible EMC solutions. In addition to EMC tests and tests under extreme environmental conditions, we also carry out shock and vibration tests in our own laboratory.
For particularly demanding projects, we at REO develop customized solutions in close cooperation with our customers. Our many years of experience and constant innovation, inspired by the diverse requirements of industries such as rail technology and wind energy, enable us to create the ideal tension for our customers’ products.
