Abstract
DISPOSITIVO PARA EL CONTROL DE MOTORES DE INDUCCION. ESTE CONTROL SE REALIZA POR LA DETERMINACION DEL DESFASE ENTRE EL VOLTAJE Y LA CORRIENTE DE ALIMENTACION DEL MOTOR Y POSTERIOR COMPARACION CON UN VALOR PREDETERMINADO PARA LA VARIACION DE LA ENERGIA DE ALIMENTACION CUANDO SE EXCEDE UN VALOR LIMITE. LA COMPARACION MENCIONADA SE ESTABLECE POR MEDIO DE UN CONTADOR DE LOS PULSOS GENERADOS POR UN OSCILADOR DURANTE EL TIEMPO QUE EL VOLTAJE HA PASADO DE UN VALOR DE LA FASE DETERMINADO, Y EL INSTANTE EN QUE LA CORRIENTE ALCANZA DICHO VALOR. ESTE PROCEDIMIENTO ES APLICABLE A BOMBAS SUMERGIBLES MOVIDAS POR MOTORES DE INDUCCION MONOFASICOS O TRIFASICOS.
