Abstract

UN DISPOSITIVO DE CONTROL COMPRENDE DOS ELECTROIMANES (61, 62) EN UN CIRCUITO DE SUMINISTRO DE CORRIENTE RESPECTIVO (41, 44); 42, 44) QUE INCLUYE UN CONMUTADOR DESVIADO (20, 21) QUE TIENE UNOS TERMINALES DE SALIDA PRIMERO Y SEGUNDO (2, 4). LOS INTERRUPTORES SON DESVIADOS HACIA EL PRIMER TERMINAL DE SALIDA (2). CUANDO LOS MAGNETOS SE MUEVEN HACIA UN ESTADO ACTIVO CONTRA LA FUERZA DE DESVIACION, EL INTERRUPTOR EN UN CIRCUITO CONMUTA DESDE SU PRIMER TERMINAL (2) HASTA EL SEGUNDO TERMINAL (4) CON EL QUE SE CONECTA EL IMAN. LOS TERMINALES PRIMERO Y SEGUNDO (2, 4) DE LOS CONMUTADORES (20, 21) SE CONECTAN DE MANERA CRUZADA, DE FORMA QUE UNA SEÑAL DE CONTROL (S1, S2) HACIA EL PRIMER CIRCUITO SUMINISTRARA ENERGIA, EN PRIMER LUGAR, AL IMAN DEL SEGUNDO CIRCUITO, Y VICE VERSA. EL IMAN PERMANECE EN UN ESTADO ACTIVO SI LA CONMUTACION DE LOS INTERRUPTORES TIENE LUGAR DENTRO DEL PERIODO DE TIEMPO MEDIDO PARA QUE UNO DE LOS IMANES ABANDONE SU ESTADO ACTIVADO DESPUES DE LA DESACTIVACION, ES DECIR, CUANDO LASDOS SEÑALES DE CONTROL (S1, S2) SE APLICAN DENTRO DE ESTE PERIODO DE TIEMPO. EL DISPOSITIVO DE CONTROL SE PUEDE UTILIZAR, POR EJEMPLO, PARA EL CONTROL CON DOS MANOS DE EMBRAGUES Y FRENOS NEUMATICOS EN PRENSAS EXCENTRICAS.
