Fusion d'Exxelia Microspire et Exxelia N'Ergy

Exxelia annonce la fusion de ses deux sociétés Exxelia Microspire et Exxelia N’Ergy. Les deux entités sont désormais rassemblées sous un même nom : Exxelia Magnetics.

Exxelia Magnetics regroupe toutes les activités de conception, fabrication et industrialisation de composants magnétiques bobinés, du groupe en France : transformateurs et inductances, électroaimants, rotors et stators.

Cette fusion vise à améliorer les services réalisés auprès des clients et autres collaborateurs mais également à simplifier les démarches administratives et commerciales. L’organisation actuelle des entreprises, les sites et leurs fonctions allouées restent inchangés.

Exxelia Microspire conçoit, industrialise et fabrique depuis plus de 35 ans des composants bobinés : transformateurs et inductances, électroaimants, rotors et stators.

Exxelia Microspire dispose de plusieurs sites de fabrication dont notamment des sites à faibles coûts de production nouvellement installés, permettant de proposer des solutions compétitives.

Le savoir-faire d’Exxelia Microspire inclut les technologies standards de bobinage linéaire (formats RM, ETD, EP, EFD, ER, EQ..) et toroïdal. Pour les marchés à environnements sévères (chocs, vibration, hautes températures, …). Exxelia Microspire dispose de technologies spécifiques et innovantes telles que les technologies SESI, TT et CCM.

La qualification de ses technologies, la définition des règles de conception associées et son organisation industrielle lui permettent de proposer à ses clients des solutions optimales.

Exxelia N’Ergy est spécialisée dans la conception, la fabrication de composants électromagnétiques passifs spécifiques, en petite et moyenne série.

Exxelia N’Ergy propose :

  • l’étude et la conception de composants électromagnétiques spécifiques avec conducteurs cuivre ou aluminium destinés aux domaines de la conversion d’énergie de produits embarqués,
  • la fabrication de bobinages linéaires ou toriques en petite et moyenne série en fourniture complète ou partielle,
  • le surmoulage de composants électromagnétiques ou de cartes (potting),
  • le contrôle électrique 50 ou 400 Hz.

Exxelia's Smart Magnetic: Breakthrough technology for more compact and powerful converters

This advance makes it possible to design more compact, lighter converters. However, the advantages of this technology are not limited to these fundamental aspects. In this article, we will explore in detail the multiple functional, economic and environmental benefits offered by Exxelia's Smart Magnetic technology.   Functional advantages for increased reliability: The Smart Magnetics project makes it possible in particular to optimize the Dual Active Bridge topology which requires the combination of a transformer and a choke. The Dual Active Bridge converter is a technology that is becoming widespread because it allows bidirectional power transmission. This meets the challenges of electrical systems (recovery + supply of energy), Integrating the Dual Active Bridge (DAB) transformer and choke into a single component has significant functional advantages. Unlike assembling two separate components, using an integrated component eliminates interconnections. The repeatability and reproducibility of the processes guarantee perfect control of the electrical characteristics, and ensure optimum performance of the converter. In addition, this consolidation reduces the number of components required, which improves the reliability of the final product.   Rationalization of the value chain for optimized production costs: The Smart Magnetic project also contributes to improving the value chain through effective streamlining. By replacing two distinct components with a single component, the management of the components of the circuit is simplified. From the customer's point of view, there is only one product to supply, one product to integrate/assemble in the system. These simplifications result in high added value and increased competitiveness on the market.   Contribution to a more environmentally friendly industry: By adopting Smart Magnetic solutions, the benefits go beyond simply improving energy efficiency. This innovation also reduces the consumption of raw materials by using less material in the Smart Magnetic component compared to standard formats requiring two separate components. As a result, this technology contributes to the preservation of natural resources. In addition, Smart Magnetic responds to the challenges posed by the electrification of vehicles, whether in air, land or sea transport, by promoting the deployment of solutions that are less dependent on fossil fuels.   Various applications: The versatility of Smart Magnetic solutions makes it suitable for many applications. For example, it can be used as a bi-directional converter between batteries and circuits, for power applications or even in resonant converter topologies. It is also useful in applications requiring high current and in Multi-output flyback converters. This diverse range of applications testifies to the flexibility of the Smart Magnetic project.   A project ? Do not hesitate to contact us.    

NASA's X-59 QueSST: Exxelia is on board

 If the program lives up to its promise, it could lead to the emergence of supersonic transport aircraft capable of flying over land, without the limitations imposed on Concorde in its day. For this project, Exxelia mainly produces coils from our US sites. Our components are intended for the aircraft engine.     With its elongated nose, its "humped" wings and its small scattered lifting surfaces, the X-59 is unlike any other aircraft. An exceptional configuration for exceptional capabilities. Credits: NASA   It will fly at a speed of 1.5 Mach (1.5 times the speed of sound), or more than 1,800 kilometers per hour. NASA hopes that its aircraft will eventually be used in civil aviation.   If the tests are successful, the X-59 QueSST could have two revolutionary effects on the U.S. and even the world's aeronautical landscape: The test aircraft could serve as inspiration for future mass-produced transport aircraft, whether airliners or business jets. The LBFD project as a whole could lead to an evolution of current aviation regulations. Rather than banning all civilian supersonic flights over the U.S., as is the case today, NASA is proposing to introduce noise-based regulation.   Credits : Lockheed Martin, NASA
