Abstract

SE PRESENTA UN SENSOR MAGNETICO DE LA FUERZA DE TORSION PARA DETECTAR ELECTRICAMENTE UNA FUERZA DE TORSION APLICADA A UN EJE GIRATORIO EN BASE A UN CAMBIO RESULTANTE EN LA PERMEABILIDAD MAGNETICA DE LA SUPERFICIE DEL EJE. FINAS MELLAS Y AREAS DE RETENCION PARA RETENER LA FUERZA COMPRESIVA RESIDUAL DEBIDA A LAS FINAS MELLAS SE FORMAN SOBRE LA SUPERFICIE DEL EJE GIRATORIO. DE ACUERDO CON ESTA DISPOSICION, EL PROCESO DE MAGNETIZACION RESULTANTE DE LA APLICACION DE UN CAMPO MAGNETICO EXCITADOR Y DE LA FUERZA DE TORSION SOBRE EL EJE GIRATORIO PROVOCA MENOR MAGNETIZACION DEBIDO AL DESPLAZAMIENTO DE LA PARED DEL CAMPO MAGNETICO Y CONSTA PRINCIPALMENTE DE ROTACION MAGNETICA REVERSIBLE, CON EL RESULTADO DE UNA HISTERESIS REDUCIDA EN EL PROCESO DE MAGNETIZACION. LA HISTERESIS REDUCIDA PROVOCA MENOS HISTERESIS INVOLUCRADA EN LA DETECCION DE LA FUERZA DE TORSION Y MAYOR SENSIBILIDAD DE DETECCION, RESULTANDO ASI EN UNA ALTA EXACTITUD DE LA DETECCION DE LA FUERZA DE TORSION. ADEMAS, TRABAJANDO LA SUPERFICIE DEL EJE GIRATORIO CON EL PROPOSITO DE FORMAR LAS FINAS MELLAS SOBRE EL MISMO, LOS MICRODEFECTOS PRESENTES SOBRE LA CAPA SUPERFICIAL DEL EJE GIRATORIO SE REDUCEN O ELIMINAN Y ASI PUEDE OBTENERSE UNA HISTERESIS REDUCIDA Y UNA SENSIBILIDAD MEJORADA EN EL PROCESO DE DETECCION DE LA FUERZA DE TORSION.
