Abstract
"COMPOSTO MAGNéTICO PARA APLICAçõES EM CORRENTE ALTERNADA, PROCESSO PARA FABRICAçãO DO MESMO E USO". é revelado um composto magnético para aplicações de corrente alternada com propriedades magnéticas aperfeiçoadas (isto é, baixas perdas histereticas e baixas perdas de corrente parasita). o composto compreende a consolidação das partículas microlamelares metálicas magnetizáveis, cada uma possuindo superfícies, superior e inferior, e extremidades opostas. As superfícies, superior e inferior, são revestidas com um revestimento dielétrico para aumentar a resistividade do composto e reduzir perdas de corrente parasita. O revestimento dielétrico é fabricado de um material refratário e as extremidades das particulas lamelares são metalurgicamente ligadas umas as outras, para reduzir as perdas histereticas do composto. é também revelado um processo para fabricação do mesmo. O composto é apropriado para fabricação de dispositivos para aplicações de corrente alternada, tais como, transformadores, estatores e rotor de motores, geradores, alternadores, concentradores de campo, difusores, relés, acionadores eletromecânicos, sincro-resolvedores, etc.
