Title
(EN) MANUFACTURING OF FERROMAGNETIC FILM FOR TRANSFORMER AND MOTOR CORES
(FR) FABRICATION DE PELLICULE FERROMAGNETIQUE POUR NOYAUX DE TRANSFORMATEURS ET DE MOTEURS
Abstract
(EN)
A core for an electromagnet is made by applying a thin coating of iron on a thin substrate, i.e. a film, of a polymer. The coated film is formed, e.g. wound, to a core. The iron coating is applied by an iron carbonyl process or electrolytically or by spraying. The core is used in transformers or dynamo-electric machines.
(FR)
On produit un noyau d'électroaimant en appliquant un mince revêtement de fer sur un substrat mince, c'est-à-dire une pellicule, de polymère. La pellicule recouverte est formée, par exemple enroulée, sur un noyau. Le revêtement de fer est appliqué par un processus à base de carbonyle de fer, ou par un procédé électrolytique ou par pulvérisation. Ce noyau est utilisé dans des transformateurs ou des machines dynamoélectriques.
