Abstract

CONJUNTO DE MANCAL MAGNÉTICO E TURBOMÁQUINA. Trata-se de um conjunto de mancal magnético para uma máquina giratória que tem um eixo de rotor (12), que compreende um circuito magnético de estator preso a um elemento de suporte estacionário e que compreende pelo menos um corpo de material ferromagnético e pelo menos uma bobina, que tanto é adaptado em um alojamento anular protetor que deixa descoberta uma superfície de revolução do dito corpo ferromagnético (22) quanto a uma superfície de revolução da dita uma bobina, sendo que o conjunto de mancal magnético compreende um colar de empuxo anular (16) preso ao eixo de rotor (12) e que se estende radialmente para o circuito magnético de estator através de uma porção radial (16b), sendo a dita porção radial (16b) voltada para as superfícies descobertas do dito corpo ferromagnético e a dita uma bobina. O colar de empuxo anular (16) compreende pelo menos um canal de fluxo (30).
