Abstract

Dispositif de concentration de flux pour exercer des forces de traction électromagnétiques. Le dispositif comprend des organes pour créer des lignes de force électromagnétiques de répulsion à montée lente en intensité, à partir d'un enroulement secondaire présentant la forme d'un cylindre, et des organes pour supprimer rapidement ces lignes de force afin de créer une grande force de traction électromagnétique, à montée élevée en intensité au niveau de l'enroulement secondaire. Des moyens sont également prévus, à l'intérieur dudit enroulement, pour que la force de traction s'exerce suivant l'axe de cet enroulement secondaire. Application au formage et au débosselage de pièces conduisant l'électricité.
