Abstract

Un procédé de fabrication de boucles de circuits magnétiques pour transformateur polyphasé à partir d’un feuillard magnétique, le procédé comprenant les étapes de : a) fourniture d’un feuillard magnétique de largeur constante sous la forme d’un rouleau enroulée autour d’un premier mandrin circulaire et s’étendant le long d’un axe longitudinal ; b) réalisation d’un premier et un deuxième demi-rouleaux par tronçonnage du rouleau, les deux demi-rouleaux d’axe longitudinal comprenant chacun une surface de délimitation respective qui est formée à l’issue de sa séparation avec l’autre demi-rouleau, le tronçonnage s’effectuant de biais suivant un angle θ par rapport à l’axe longitudinal de sorte que le premier demi-rouleau constitue une première boucle en présentant sa surface de délimitation qui est orientée extérieurement par rapport à son axe longitudinal, tandis que la surface de délimitation du deuxième demi-rouleau est d’orientation opposée à la surface de délimitation du premier demi-rouleau ; c) mise en conformité des premier et deuxième demi-rouleaux pour constituer deux boucles, incluant au moins une sous-étape de déroulement et ré-enroulement à l’envers du deuxième demi-rouleau sur un mandrin.
