Abstract

UN MOTOR LINEAL QUE TIENE UN CIRCUITO MAGNETICO Y UNA BOBINA MOVIL, TENIENDO EL CIRCUITO MAGNETICO UNA CULATA LINEAL EN EL CENTRO DEL CIRCUITO Y UN PAR DE IMANES LINEALES, FORMANDO LA CULATA LINEAL Y EL PAR DE IMANES LINEALES UN PAR DE HUECOS LINEALES CON LA CULATA LINEAL INTERPUESTA ENTRE ELLOS, APLICANDO EL CIRCUITO MAGNETICO UN CAMPO MAGNETICO A LOS HUECOS LINEALES, ESTANDO LA BOBINA MOVIL MONTADA SOBRE LA CULATA LINEAL DEL CIRCUITO MAGNETICO DE MANERA QUE SE PUEDE MOVER A LO LARGO DE LA CULATA LINEAL MEDIANTE UNA ACCION ELECTROMAGNETICA AL CIRCUITO MAGNETICO CUANDO LA BOBINA MOVIL ES PROPULSADA, EN DONDE EL IMAN LINEAL TIENE UNA FUERZA MAGNETICA MAYOR EN LOS EXTREMOS OPUESTOS EN EL SENTIDO LONGITUDINAL DEL IMAN LINEAL QUE EN UNA ZONA INTERMEDIA, LA RELUCTANCIA MAGNETICA DEL CIRCUITO MAGNETICO SE AUMENTA PARA OBTENER UNA CORRIENTE EXCITADORA DE LA BOBINA MOVIL CORRESPONDIENTE AA RELUCTANCIA MAGNETICA CUANDO LA BOBINA MOVIL SE MUEVE EN EL AREA INTERMEDIA DEL IMAN LINEAL, O EL CIRCUITO MAGNETICO ESTA MONTADO SOBRE UNA PLACA HECHA DE UN MATERIAL QUE TIENE LA MISMA RELACTANCIA MAGNETICA QUE LA CULATA LINEAL. UN APARATO DE GRABACION/REPRODUCCION DE LA INFORMACION TIENE UNA ETAPA DE TRANSPORTE DE TARJETAS PARA TRANSPORTAR UN MEDIO DE GRABACION DE LA INFORMACION Y UNA UNIDAD LASER PARA RADIAR UN RAYO LASER AL MEDIO DE GRABACION DE LA IMPORTACION, ESCRIBIENDO Y LEYENDO EL APARATO DE GRABACION/REPRODUCCION DE LA INFORMACION A Y DESDE EL MEDIO DE GRABACION DE LA INFORMACION AL TIEMPO QUE MUEVE DE MANERA RECIPROCA LA ETAPA DE TRANSPORTE DE TARJETAS Y MUEVE LINEAL Y RECIPROCAMENTE EL MEDIO DE GRABACION DE LA INFORMACION Y APLICA UN RAYO LASER AL MEDIO DE GRABACION DE LA INFORMACION, EN DONDE EL APARATO TIENE UNA UNIDAD DE TRANSPORTE EL PLANO DE LA FUERZA EXCITADORA MEDIANTE MEDIOS EXCITADORES PARA MOVER RECIPROCAMENTE LA ETAPA DE TRANSPORTE DE TARJETAS ESTA HECHA DE MANERA SUSTANCIALMENTE NIVELADA AL CENTRO DEL EJE DE GUIA PARA MOVER LA ETAPA DE TRANSPORTE.
