Abstract
Perfeccionamientos en los dispositivos de mando de motores eléctricos, de corriente continua y excitación independiente por imanes permanentes, del tipo que comprenden un puente rectificador para la alimentación de corriente continua al motor, un conjunto regulador que comprende un triac en el ramal de corriente alterna del puente rectificador, estando determinado el ángulo de cebado por un condensador conectado en serie con una red de resistencias, y medios para limitar la energía suministrada en el ramal de corriente alterna del puente rectificador, caracterizados por el hecho de comprender estos medios una resistencia (Ra) suplementaria susceptible de ser conectada en serie con la red de resistencias cuando la citada tensión sobrepase un valor determinado.
