Abstract
643,571. Exciting dynamo-electric machines. MATERIEL ELECTRIQUE. Aug. 12, 1946, No. 23882. Convention date, Aug. 19, 1943. Drawings to Specification. [Class 35] A generator is excited by a series dynamo operating on the straight part of its characteristic which is such that the effect of the resistance of the field circuit is wiped out and the main generator may be controlled by the introduction of a small additional current into the field circuit.
