Abstract

SE DESCRIBE UN SENSOR ANGULAR INDUCTIVO PARA UN AUTOMOVIL CON UN CIRCUITO OSCILADOR, QUE GENERA UNA SEÑAL DE TENSION ALTERNA PERIODICA Y SE ACOPLA EN UNA BOBINA DE EXCITACION, CON AL MENOS UNA BOBINA DE RECEPCION Y UN CIRCUITO DE VALORACION PARA LAS SEÑALES INDUCIDAS EN AL MENOS UNA BOBINA DE RECEPCION Y UN ELEMENTO DE ACOPLAMIENTO INDUCTIVO MOVIL, QUE INFLUYE LA INTENSIDAD DEL ACOPLAMIENTO INDUCTIVO ENTRE LA BOBINA EXCITADORA Y LAS BOBINAS DE RECEPCION. EL SENSOR ANGULAR DE ACUERDO CON LA INVENCION SE CARACTERIZA A TRAVES DE UN CIRCUITO OSCILADOR "BLANDO". MEDIANTE ACOPLAMIENTO DE UNA FRECUENCIA DE PERTURBACION EN EL SISTEMA DE BOBINAS, QUE SE ENCUENTRA EN LA POSIBILIDAD DE LA FRECUENCIA DEL OSCILADOR, EL CIRCUITO OSCILADOR ADAPTA LA FRECUENCIA DE OSCILADOR Y LA SITUACION DE FASE DEL OSCILADOR A LA FRECUENCIA DE PERTURBACION. LOS EFECTO DE SUPERPOSICION SE EVITAN DE FORMA COMPLETA.
