Highlight of Drive Technology
EDGE-WINDING
Advancing Cooling and Efficiency
With the introduction of the latest generation of N CNW choke and filter series, REO is further advancing the use of EDGE winding technology. With increased effectiveness and simultaneously lower weight, the new series with upright winding exhibit extremely efficient cooling due to their single-layer construction – especially with forced cooling.
Due to the improved cooling technology, depending on the design, aluminum conductors can be used as a substitute for copper conductors. In conjunction with automated manufacturing, production costs could therefore be further reduced.
The lower weight and smaller dimensions are possible thanks to the reduction of skin and proximity losses. EDGE Winding is particularly suitable for semiconductors based on new materials such as silicon carbide (SiC) and gallium nitride (GaN).
The near-elimination of insulating materials enhances component lifespan.
Up to 10% reduction in weight
“Edge-Winding technology is an innovation from our development team, which continuously researches the latest technologies and always thinks in new ways. We recognized the opportunity of the new winding technology and have been able to produce in small or large series since 2020, offering our customers extremely fast delivery times. I am particularly impressed by the cooling properties of the N CNW series, which, due to its single-layer design, enables alternative materials and virtually eliminates the need for insulating material. On the one hand, dimensions and weight are reduced, and on the other hand, lifespan increases, and the range of application is greater than with conventional winding techniques.” – Sven Reimann, Member of the Board REO AG

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.
