Abstract

METODO DE RELAJACION DE TENSIONES INTERNAS EN NUCLEOS DE CABEZAS SENSORAS DE CAMPOS MAGNETICOS. APLICABLE EN EL PROCESO DE FABRICACION DE NUCLEOS DE CABEZAS SENSORAS (1) DE CAMPOS MAGNETICOS COMPUESTAS POR UN NUCLEO DE MATERIAL AMORFO FERROMAGNETICO SOBRE EL QUE SE ARROLLA DIRECTAMENTE UN PRIMER DEVANADO QUE CONSTITUYE LA BOBINA EXCITADORA, Y QUE INCLUYE ADEMAS UN SEGUNDO Y UN TERCER DEVANADOS QUE CONSTITUYEN LAS BOBINAS SENSORA Y COMPENSADORA RESPECTIVAMENTE, AMBAS ARROLLADAS SOBRE UN TUBO EN EL QUE SE INTRODUCE EL CONJUNTO FORMADO POR EL NUCLEO Y LA BOBINA EXCITADORA.SE APLICA UNA PRIMERA CORRIENTE ELECTRICA (2) AL NUCLEO DE DICHA CABEZA SENSORA (1) QUE SE CALIENTA DEBIDO A SUS PERDIDAS ELECTRICAS. ADEMAS SE APLICA UNA SEGUNDA CORRIENTE ELECTRICA ALTERNA (3) A UNA DE LAS BOBINAS QUE RODEAN AL NUCLEO Y QUE ACTUA COMO IMANADORA; SE REALIZA UN ANALISIS (4) DE LA SEÑAL INDUCIDA EN OTRA DE LAS BOBINAS QUE RODEA AL NUCLEO Y QUE ACTUA COMO DETECTORA, Y FINALMENTE SE TOMA LA DECISION (5) SOBRE LAFINALIZACION DEL PROCESO (6) CUANDO LA SEÑAL INDUCIDA EN LA BOBINA DETECTORA REDUCE SU NIVEL DE FORMA SUSTANCIAL.
