Abstract

CAPTADOR DE DETERMINACION DE POSICION ANGULAR DE DOS PIEZAS COAXIALES (27,40) EN ROTACION RELATIVA QUE FUNCIONAN POR VARIACION DE LA RELUCTANCIA MAGNETICA. LOS CAPTADORES (25,26) DEL INVENTO, EMPLEADOS AISLADAMENTE O COMO PLURALIDAD, FORMAN ASI UN CONJUNTO DE DETERMINACION DE POSICION ANGULAR, CADA UNO DE LOS CUALES CONSTA DE UN ROTOR DENTADO (1) Y DE UN ESTATOR DENTADO (2), POSEYENDO ESTE ULTIMO DOS VECES MAS DIENTES QUE ELROTOR. HAY UNOS ELEMENTOS DE ENLACE MECANICO (41,42) ENTRE LOS ROTORES (1), POR UNA PARTE, Y ENTRE LOS ESTATORES (2), POR OTRA; EL DESPLAZAMIENTO ANGULAR ENTRE LOS DIENTES (3 Y 4) ES DIFERENTE PARA CADA CAPTADOR, SIENDO LA DIFERENCIA GENERALMENTE UN MULTIPLO DEL COCIENTE DE 2 (PI) POR EL NUMERO DE DIENTES Y EL NUMERO DE CAPTADORES, HABIENDO UN BOBINADO BIFASICO O DOS BOBINADOS MONFASICOS EN EL ROTOR (1) O EN EL ESTATOR (2) DE CADA CAPTADOR Y LA CORRIENTE ALTERNA QUE LO RECORRE DEPENDE DE LA POSICION RELATIVA DEL ESTATOR (2) Y DEL ROTOR (1). ESTE DISPOSITIVO ESTA CONCEBIDO MAS ESPECIALMENTE PARA LA ROBOTICA.
