Abstract

UN SISTEMA QUE CONSTA DE UN MOTOR SECUNDARIO COMO UNA BOMBA HIDRAULICA (10) ACCIONADA POR UN MOTOR PRINCIPAL COMO UN MOTOR (19) ACCIONADO, EN FUNCIONAMIENTO, POR UN SUMINISTRO ELECTRICO DE CORRIENTE ALTERNA (CA) EN DONDE LA OPERACION DEL MOTOR SECUNDARIO (10) SE VE AFECTADA POR CUALQUIER VARIACION DE FRECUENCIA EN UN SUMINISTRO DE CA DE VOLTAJE CONSTANTE. EL SISTEMA ADEMAS COMPRENDE ELEMENTOS DE AJUSTE (90) EN FUNCIONAMIENTO ACCIONADOS POR EL MISMO SUMINISTRO DE CA QUE EL MOTOR PRINCIPAL (19), QUE TIENE DE FORMA INHERENTE SUBSTANCIALMENTE LAS MISMAS CARACTERISTICAS DE FUNCIONAMIENTO QUE EL MOTOR PRINCIPAL, QUE ESTA ACOPLADO AL MOTOR SECUNDARIO (10) Y OPERABLE PARA AJUSTAR EL RANGO DE OPERACION DEL MISMO DE ACUERDO CON LAS VARIACIONES EN LA FRECUENCIA DEL SUMINISTRO DE CA.
