Abstract
L'invention concerne une plaque d'adhérence à magnétisme permanent La plaque d'adhérence de l'invention est constituée d'aimants permanents 2 disposés dans un logement ferromagnétique, ainsi que d'une plaque de recouvrement 3 servant de surface d'adhérence, recouvrant les aimants permanents 2 et le logement, appliquée directement sur les faces polaires des aimants permanents 2 et ayant une épaisseur dépendant du flux magnétique de ces aimants 2. Des trous 8 sont pratiqués dans cette plaque 3. L'invention est utilisée pour améliorer les propriétés d'adhérence magnétique des plaques de recouvrementThe invention relates to an adhesion plate with permanent magnetism. The adhesion plate of the invention consists of permanent magnets 2 arranged in a ferromagnetic housing, as well as a cover plate 3 serving as an adhesion surface, covering the permanent magnets 2 and the housing, applied directly to the pole faces of the permanent magnets 2 and having a thickness depending on the magnetic flux of these magnets 2. Holes 8 are made in this plate 3. The invention is used to improve the magnetic adhesion properties of cover plates
