Title (EN) A CORE ELEMENT FOR A MAGNETIC COMPONENT AND A METHOD FOR MANUFACTURING THE SAME
(FR) ÉLÉMENT DE NOYAU POUR UN COMPOSANT MAGNÉTIQUE ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) A core element for a magnetic component comprises a plurality of ferromagnetic sections (216-219) for conducting a magnetic flux. Adjacent ones of the ferromagnetic sections are connected to each other with ferromagnetic isthmuses (221) keeping the adjacent ones of the ferromagnetic sections a distance apart from each other, and/or the gaps between the ferromagnetic sections are filled with electrically insulating solid material (223) and adjacent ones of the gaps are connected to each other via openings (224) through the ferromagnetic sections and filled with electrically insulating solid material (225). The ferromagnetic sections can constitute for example a stack of ferromagnetic sheets or a bundle of ferromagnetic filaments. The core element can be manufactured by three-dimensional printing and thus it is possible to make core elements which are not possible or at least not cost effective to be made by shaping ferromagnetic sheets which are originally planar.
(FR) Un élément de noyau pour un composant magnétique comprend une pluralité de sections ferromagnétiques (216-219) pour conduire un flux magnétique. Les sections ferromagnétiques adjacentes sont reliées l'une à l'autre par des applications ferromagnétiques (221) maintenant les sections ferromagnétiques adjacentes à une distance l'une de l'autre, et/ou les espaces entre les sections ferromagnétiques sont remplis d'un matériau solide électriquement isolant (223) et les espaces adjacents sont reliés l'un à l'autre par l'intermédiaire d'ouvertures (224) à travers les sections ferromagnétiques et remplis d'un matériau solide électriquement isolant (225). Les sections ferromagnétiques peuvent constituer, par exemple, un empilement de feuilles ferromagnétiques ou un faisceau de filaments ferromagnétiques. L'élément de noyau peut être fabriqué par impression en trois dimensions et, par conséquent, il est possible de fabriquer des éléments de noyau qui ne sont pas possibles ou au moins peu coûteux à fabriquer en façonnant des feuilles ferromagnétiques qui sont à l'origine planes.
