Abstract
EN UN APARATO PARA INDICAR LA POSICION ANGULAR DE UN ELEMENTO GIRATORIO, UNA BOBINA IMPULSORA (51) ESTA PROVISTA CON SU EJE CORRESPONDIENTE AL EJE DE ROTACION DEL ELEMENTO GIRATORIO. UNA BOBINA (65) ESTA ENROLLADA ALREDEDOR DEL ELEMENTO GIRATORIO, Y UN CONDENSADOR (66) ESTA PROVISTO EN LA BOBINA (65) PARA FORMAR UN CIRCUITO RESONANTE LC. LA BOBINA (65) EN EL ELEMENTO GIRATORIO ESTA ENROLLADA DE MODO QUE LA APLICACION DE UN CAMPO MAGNETICO ALTERNANTE A LA BOBINA IMPULSORA (51) INDUZCA UNA RESONANCIA EN EL CIRCUITO LC QUE ES CONSTANTE PARA TODAS LAS POSICIONES ANGULARES DEL ELEMENTO GIRATORIO. HAY PROVISTAS BOBINAS DE RECOGIDA (53, 55) DE MODO QUE LOS PLANOS DE ESTAS BOBINAS Y LA BOBINA IMPULSORA (51) SEAN ORTOGONALES. LA RESONANCIA DEL CIRCUITO LC PRODUCE SEÑALES EN LAS BOBINAS DE SALIDA (53, 55) QUE DEPENDEN DE LA POSICION ANGULAR DEL ELEMENTO GIRATORIO. LA SEÑALES PUEDEN SER PROCESADAS PARA DETERMINAR ESA POSICION ANGULAR, Y EL PROCESAMIENTO ES SIMPLIFICADO CON ESTA DISPOSICION DE BOBINASDE SALIDA YA QUE LAS SEÑALES PRODUCIDAS EN LAS MISMAS SON SEÑALES DE CUADRATURA.
