Abstract

ARTIGO LAMINAR PARA USO ELéTRICO E UM MéTODO E MáQUINA PARA PRODUZIR O REFERIDO ARTIGO. A presente invenção refere-se ao artigo laminar (1) para uso elétrico que compreende uma pluralidade de primeiras laminações de metal sobrepostas (2), fixadas juntas. Cada uma das primeiras laminações (2) é dotada de pelo menos um prendedor (3, 3a, 3b) projetando-se uma primeira superfície (4) e definindo uma reentrância (5, 5b) em seu lado oposto. Cada prendedor (3, 3a, 3b) de uma laminação (2) é disposto para encaixar em uma reentrância (5, 5b) de uma laminação adjacente. O artigo apresenta segundas laminações (9) interpostas entre pelo menos duas primeiras laminações adjacentes (2) fixadas juntas. As segundas laminações (9) são dotadas de aberturas passantes (10) que são atravessadas pelos prendedores (3, 3a, 3b) que fixam as primeiras laminações adjacentes juntas. O método consiste em corte em matriz de uma pluralidade de laminações de uma folha de metal, girando as laminações cortadas em matriz e sobrepondo as mesmas, para, então, fixá-las juntas de maneira predeterminada. As laminações podem ser cortadas em matriz com um eixo geométrico de referência girado através de um ângulo predeterminado em torno de um eixo geométrico de referência da folha de metal, para limitar as rotações a serem impostas nas laminações durante sua fixação mútua.
