Abstract

"MéTODO E DISPOSITIVO PARA ESTIMAR A POSIçãO DE UMCORPO ACIONADOR EM UM ACIONADORELETROMAGNéTICO PARA CONTROLAR UMA VáLVULA DEMOTOR". Onde o método e dispositivo para estimar a posição (x)de um corpo acionador (4) em um acionador eletromagnético (1)para controlar uma válvula (2) de um motor, segundo o qual ocorpo acionador (4), que é ao menos parcialmente fabricado commaterial ferromagnético, é deslocado em direção a pelo menos umeletromagneto (8), através do efeito da força de atraçãoeletromagnética gerada pelo próprio eletromagneto (8); a posição(x) do corpo acionador (4) em relação ao eletromagneto (8) édeterminada com base no valor adotado pela relutância (R) de umcircuito magnético (18) constituído pelo eletromagneto (8) e pelocorpo acionador (4).
