Abstract

EN UNA BOBINA DE IGNICION (300) EN LA CUAL UNA PORCION DE DISCONTINUIDAD AEREA (A1-A2) SE PROVEE EN UNA PORCION DE UN ALMA DE ACERO (510,520) FORMANDO UN CIRCUITO MAGNETICO CERRADO, EL CUAL INCLUYE UNA PARTE CENTRAL DE ACERO DE EXCITACION (50) TENIENDO UNA BOBINA (310) PRIMARIA Y UNA BOBINA SECUNDARIA (320) ENROLLADAS A SU ALREDEDOR, Y UN FUERTE IMAN (530) PERMANENTE SE INSERTA EN LA PORCION DE DISCONTINUIDAD AEREA. EL CIRCUITO MAGNETICO CERRADO SE CONSTRUYE PARA TENER EL ALMA DE ACERO Y PROVEER IMANTACION PERMANENTE CON RESPECTIVAS FORMAS CONVENIENTES, DIMENSIONES, PROPIEDADES,ETC. DE MODO QUE TENGA LA MAYORIA DE LAS CARACTERISTICAS DE LOS POTENTES IMANES PERMANENTES, REDUCIENDO DRASTICAMENTE EL TAMAÑO Y PESO DE LA BOBINA DE IGNICION. ADEMAS, UNA MEJORA CONCRETA DE LA CONSTRUCCION DEL CIRCUITO MAGNETICO CERRADO DE LA BOBINA DE IGNICION SE CONSIGUE PARA ASEGURAR UNA EXCELENTE FUNCION DE CONVERSION MAGNETO ELECTRICA DE LA BOBINA DE IGNICION.FIG 9.
