(EN) HYBRID MAGNET AND METHOD FOR THE PRODUCTION THEREOF
(FR) AIMANT HYBRIDE ET PROCÉDÉ DE FABRICATION
Abstract:
(DE) Verfahren zur Herstellung eines Hybridmagneten (1), umfassend zumindest die folgenden Verfahrensschritte: A) Erzeugen einer hartmagnetischen Schicht (13) aus einem hartmagnetischen Material (5), B) Erzeugen einer weichmagnetischen Schicht (14) aus einem weichmagnetischen Material (6), und C) Erzeugen einer Trennschicht (15) aus einem magnetisch passiven Material (7), wobei durch jeweils mehrfaches Anwenden der Verfahrensschritte A), B) und C) ein Hybridmagnet (1) geformt wird, der einen Schichtaufbau aufweist.
(EN) The invention relates to a method for producing a hybrid magnet (1), comprising at least the following method steps: A) producing a hard magnetic layer (13) of a hard magnetic material (5), B) producing a soft magnetic layer (14) of a soft magnetic material (6), and C) producing a separating layer (15) of a magnetically passive material (7), wherein a hybrid magnet (1) having a layer structure is formed by in each case multiple application of the method steps A), B) and C).
(FR) L’invention concerne un procédé de fabrication d’un aimant hybride (1), comprenant au moins les étapes suivantes : A) fabriquer une couche en matériau magnétique dur (13) réalisée dans un matériau magnétique dur (5), B) produire une couche en matériau magnétique doux (14) réalisée dans un matériau magnétique doux (6), et C) produire une couche de séparation (15) réalisée dans un matériau magnétiquement passif (7) ; respectivement une application multiple des étapes A), B) et C) permet de former un aimant hybride (1) qui présente une structure stratifiée.
