Abstract

UN CIRCUITO DE REGULACION DE CORRIENTE PARA UN MOTOR DE VELOCIDAD VARIABLE (112). EL MOTOR COMPRENDE UN CONJUNTO FIJO QUE TIENE ARROLLAMIENTOS ADAPTADOS PARA LA EXCITACION EN AL MENOS UNA SECUENCIA PREELEGIDA Y UN CONJUNTO GIRATORIO EN RELACION DE ACOPLAMIENTO MAGNETICO AL CONJUNTO FIJO. UN ENLACE DE FUENTE DE ALIMENTACION CONECTA EL ARROLLAMIENTO A LA FUENTE DE ALIMENTACION (128) Y COMPRENDE DISPOSITIVO DE CONMUTACION DE ENERGIA (110) PARA EXCITAR SELECTIVAMENTE LOS ARROLLAMIENTO EN LA SECUENCIA PREELEGIDA CONECTANDO EL ENLACE DE FUENTE DE ALIMENTACION A LOS ARROLLAMIENTOS PARA PRODUCIR UN CAMPO ELECTROMAGNETICO PARA HACER GIRAR EL CONJUNTO GIRATORIO. LOS DISPOSITIVO DE CONMUTACION TIENEN CADA UNO UN ESTADO CONDUCTOR Y UN ESTADO NO CONDUCTOR. EL CIRCUITO REGULADOR DE CORRIENTE COMPRENDE UN CIRCUITO DE TEMPORIZACION, UN CIRCUITO DE DETECCION DE CORRIENTE Y UN CIRCUITO DE CONTROL (142). EL CIRCUITO DE TEMPORIZACION DEFINE PERIODOS PREESTABLECIDOS DURANTE LOS CUALES CADA UNO DE LOS DISPOSITIVOS DE CONMUTACION DE ENERGIA PUEDE SER NO CONDUCTOR. LOS DISPOSITIVOS DE DETECCION DE CORRIENTE DETECTAN CORRIENTE EN EL ENLACE DE FUENTE DE ALIMENTACION. EL CIRCUITO DE CONTROL CONTROLA LOS DISPOSITIVOS DE CONMUTACION DE MANERA QUE CADA UNO DE LOS DISPOSITIVOS DE CONMUTACION SEA NO CONDUCTOR CUANDO LA CORRIENTE DETECTADA SOBREPASA UN NIVEL DE REFERENCIA DE CORRIENTE DE CRESTA DURANTE LOS PERIODOS PREESTABLECIDOS. DE ESTA MANERA, EL CIRCUITO DE REGULACION DE CORRIENTE CONTROLA LA CORRIENTE QUE CIRCULA DURANTE PERIODOS CUANDO SOLO UN DISPOSITIVO DE CONMUTACION DE ENERGIA ES CONDUCTOR.
