Abstract
In a typical scheme of a pulsed DC electric drive when forming feedback impulses with a mechanical modulator, it is proposed to use two pulse formers (for example, optocouplers) and arrange them diametrically relative to the mechanical modulator. In order to form working feedback impulses in the stabilization system, it is suggested to introduce a circuit that processes the impulses from these pulse formers, determines the time position of the center between the centers of the initial impulses and generates working feedback impulses strictly at the obtained instants of time. This will allow us to exclude the mechanical modulator eccentricity effect on the repetition rate of the feedback impulses in the pulse system that stabilizes the rotational speed of the DC electric drive shaft.
