Abstract
The DC electrical motor system includes a motor having an armature DC transducer coupled to an armature current controller by a sensor/detector arrangement to control the armature current. A field DC transducer coupled to a field current controller by another sensor/detector arrangement facilitates the control of the field current. An armature-field comparator is coupled to the field current controller to help control the field current when the motor armature windings are short-circuited through windings in the armature field comparator.
