Abstract

TIENE POR OBJETO UN DISPOSITIVO PARA MEDIR EN ANGULO DE ROTACION DE UN ROTOR EN RELACION A UN ESTATOR, CARACTERIZADO PORQUE CONSTA DE 2N CAPTADORES MAGNETICOS, SIENDO N EL NUMERO DE PLANOS ELECTRICOS DEL CAPTADOR, DISPUESTOS SEGUN UNA CIRCUNFERENCIA DE FORMA FIJA EN RELACION AL ESTATOR, CONSTANDO CADA CAPTADOR DE UN CIRCUITO MAGNETICO (4,5) PROVISTO DE UNA BOBINA EMISORA (6) Y UNA BOBINA RECEPTORA (7), CARACTERIZADO PORQUE DICHO CIRCUITO MAGNETICO PRESENTA UN ENTREHIERRO, ESTANDO LOS CAPTADORES AGRUPADOS DE DOS EN DOS, ESTANDO LOS CAPTADORES DE UN MISMO GRUPO DESPLAZADOS ANGULARMENTE EN UN ANGULO DE 180 (GRADOS) /M, ESTANDO DOS GRUPOS VECINOS SEPARADOS ANGULARMENTE ENTRE SI CON UN ANGULO IGUAL A K360 (GRADOS) /M, DONDE K ES UN COEFICIENTE QUE DEPENDE DEL NUMERO DE FASE DEL CAPTADOR, M Y N SON NUMEROS ENTEROS. TODAS LAS BOBINAS EMISORAS ESTAN PUESTAS EN SERIE Y ALIMENTADAS CON UNA TENSION ALTERNA DE FRECUENCIA COMPRENDIDA ENTRE 2 Y 15 KHZ, CONSTANDO EL DISPOSITIVO ADEMAS DE UN ELEMENTO MOVIL (8,9) SOLIDARIO DEL ROTOR (1) Y PROVISTO DE M DIENTES SUJETOS QUE SE DESLIZAN POR EL ENTREHIERRO DE LOS CAPTADORES, ESTANDO LAS BOBINAS RECEPTORAS DE UN MISMO GRUPO DE CAPTADORES CONECTADAS EN SERIE. LA ENVOLTURA DE LAS SEÑALES EN LAS BORNAS DE ESTOS CONJUNTOS DE BOBINAS REPRESENTAN, EN UN DESFASAJE CERCANO, LA IMAGEN DE LA MEDIDA DEL ANGULO DE ROTACION DEL ROTOR. APLICACION EN LOS MOTORES ELECTRICOS GIRATORIOS Y LINEALES.
