Abstract

EL DISPOSITIVO COMPRENDE UN NUCLEO MAGNETICO DE GRAN PERMEABILIDAD, QUE ESTA FORMADO POR DOS MITADES (1) DEL NUCLEO EN FORMA DE E, CADA UNA DE LAS CUALES COMPRENDE TRES NUCLEOS POLARES PARALELOS (5, 7), QUE ESTAN INTERCONECTADOS POR UNA CULATA (9). LAS MITADES (1) DEL NUCLEO ESTAN COLOCADAS UNA CONTRA OTRA MEDIANTE LOS EXTREMOS LIBRES DE LOS NUCLEOS POLARES (5, 7), DISPONIENDOSE DE UN FORMERO (3) PARA DEVANAR BOBINAS ALREDEDOR DE NUCLEOS POLARES (7). LOS NUCLEOS POLARES (5) EXTERIORES SE EXTIENDEN ENTRE UN PLANO SUPERIOR MARGINAL (25) Y UN PLANO INFERIOR MARGINAL (27), CUYOS PLANOS SE EXTIENDEN PARALELOS A LAS DIRECCIONES LONGITUDINALES DE LOS NUCLEOS POLARES (5, 7) Y LAS CULATAS (9), DETERMINANDOSE LA DISTANCIA ENTRE LOS CITADOS PLANOS MEDIANTE LA ALTURA (X) DE LOS NUCLEOS POLARES EXTERIORES, QUE ES MAYOR QUE LA ALTURA (Y) DE LOS NUCLEOS POLARES CENTRALES (7). EL LIMITE O MARGEN INFERIOR DEL NUCLEO POLAR (7) CENTRAL ESTA SITUADO POR ENCIMA O POR DEBAJO DEL PLANO INFERIOR MARGINAL (27), A TAL DISTANCIA QUE EL PLANO DE SIMETRIA (31) DE LOS NUCLEOS POLARES (7), EXTENDIENDOSE PARALELO A LOS PLANOS MARGINALES (25, 27), ESTA SITUADO A MEDIO CAMINO ENTRE EL PLANO SUPERIOR MARGINAL (25) Y UN PLANO (33) QUE SE EXTIENDE PARALELO A LOS PLANOS MARGINALES, Y QUE SE SITUA DESDE 0''1 A 1 MM POR ENCIMA DEL MARGEN INFERIOR DEL FORMERO (3) PARA DEVANAR BOBINAS. UN BOBINADO (29) SOBRE EL FORMERO (3) PARA DEVANAR BOBINAS, OCUPA EXACTAMENTE EL ESPACIO DISPONIBLE EN EL LATERAL SUPERIOR Y EN EL LATERAL INFERIOR, DISMINUYENDO ASI LA ALTURA DEL TRANSFORMADOR.
