This present invention provides a novel DC dynamo which is characterized by making the magnetic lines of flux pass through an air gap between the rotator and the stator in the same direction, thus the most of armature coils can always receive the electromotive force of the same polarity in the same direction. Therefore, bidirectional energy conversion between the mechanical energy and the electrical energy of the armature coils in series can still proceed in the absence of commutators and induced the armature to generate sufficient electromotive force to conveniently regulate suitable terminal voltages and the ratios of the rotating speed and the moving speed thereof.
