Self-Oscillatory Processes in Pulse-Width Regulation of Phase Voltages of a Direct Current Valve Motor

In this article, the physical features of electromagnetic and electromechanical processes in regulated dc valve motors with pulse-width modulation of voltage on armature are considered. The features of the influence of position-dependent switching and control on the functioning of such valve electromechanical systems are analyzed. In rowing electric drives of mobile objects, the use of an adjustable motor of this type has an advantage compared with an asynchronous clock-controlled motor with a short-circuited rotor, which provides the necessary number of consecutive smooth starts.
