Abstract

Un sistema de control de tirantez constante para un motor de corriente continua propulsor de rollos o carretes, que funciona enrollando o desenrollando una bobina de material de tira que se mueve a una velocidad lineal prefijada , sistema que comprende: medios de proporcionar una señal que es función del diámetro instantáneo D de la bobina, teniendo la bobina un diámetro finido Do cuando el motor del rollo se halla en el punto de ajuste de flujo correspondiente al campo más débil; medios acoplados para recibir dicha señal de diámetro D y suministrar una señal de salida de control de campo que está acoplada al campo de excitación de dicho motor del rollo, de manera que el flujo de campo fi sea función del diámetro instantáneo D cuando D sea mayor que Do, y que el flujo de campo fi sea constante cuando D sea igual o menor que Do, medios acoplados para recibir dicha señal de diámetro D y suministrar una señal de control de salida de corriente de inducido, señal que va acoplada al inducido delmotor del rollo, de manera que cuando D sea mayor que Do la corriente de inducido Ia sea constante, y que Ia sea función de D cuando D sea igual o menor que Do, y medios acoplados para recibir dicha señal de diámetro Do dando una señal de salida que permita reducir la velocidad lineal pre-ajustada, cuando D sea igual o menor que Do.
