Abstract

MANCAL MAGNÉTICO, MÁQUINA ROTATIVA E PROCESSO PARA FABRICAÇÃO DE UM MANCAL. A presente invenção de maneira geral a mancais magnéticos para máquinas rotativas que possuem um rotor. Em particular, as realizações referem-se a mancais magnéticos para máquinas rotativas nas quais o rotor e o mancal estão, em uso, em contato com um fluido, por exemplo, uma atmosfera gasosa que é corrosiva, ácida ou que carrega partículas. Algumas realizações exemplificativas se referem especificamente a uma máquina rotativa que compreende tal mancal magnético. Mancal magnético (1) para uma máquina rotativa que possui um rotor (4), em que o mancal (1) compreende um circuito magnético de estator (5) preso a um dispositivo de suporte estacionário (2), o circuito magnético de estator (5) compreende pelo menos uma bobina (6) e um corpo ferromagnético (7) localizado em um suporte anular protetor (8), em que o suporte anular protetor (8) deixa exposta uma superfície do corpo ferromagnético (7) e uma superfície da pelo menos uma bobina (6), em que o mancal (1) compreende pelo menos um plugue anular (13) localizado na superfície da pelo menos uma bobina (6) que é deixada exposta pelo suporte anular protetor (8), e pelo fato de que o plugue anular (13) e a superfície do corpo ferromagnético (7) que é deixada exposta pelo suporte anular protetor (8) são recobertos por uma camada protetora (17).
