Abstract

Perfeccionamientos en dispositivos de regulación fina de la velocidad de un motor asíncrono polifásico con rotor bobinado, que utiliza semi- conductores agenciados para interrumpir periódicamente la corriente en las fases del rotor y cuyo cebado es accionado por circuitos de control regulables que comprenden medios para cargar un condensador por un tensión o una corriente, medios para descargar periódicamente el condensador a instantes determinados por una tensión de sincronización de periodo proporcional a la de la tensión rótorico, medios de composición de la tensión de rampa resultante de las cargas y las descargas sucesivas del condensador a una tensión continua Vr que constituye un umbral de referencia y para engendrar así frentes rígidos aplicados a los semiconductores para provocar de este medio el cebado, y medios para engendrar una tensión función de la desviación entre la velocidad rótorica real y una velocidad rótorica de consigna, y para controlar los instantes de generación delos frentes rígidos se obtiene tomando como tensión de umbral de referencia Vr la tensión función de la desviación y porque la tensión o la corriente de carga del condensador son proporcional a la frecuencia rótorica y que sirve
