Abstract

Perfeccionamientos en motores de corriente continua, del tipo que tienen un inducido y un devanado inductor, en combinación con medios para detectar la temperatura del devanado, inductor, caracterizados porque se dota a cada motor de medios sensores de voltaje para detectar la caída de voltaje resistivo a través del devanado inductor debido al flujo de corriente en el devanado, medios sensores de corriente para detectar la corriente en el devanado inductor, medios para comparar el voltaje detectado a través del devanado inductor de corriente y proporcionar una señal de salida cuando la comparación indica que la temperatura del devanado excede de un nivel predeterminado.
