Annotation. The demonstration of an active increase in the use of electric drive devices at a wide variety of capacities indicates the need for further study and possible design for both large and small capacities. For such a review and hypothetical analysis, a real work has been created analyzing all outgoing aspects.

Before starting the study, it is necessary to pay attention to the very definition of an electric drive, which is abbreviated as electric drives or EP, which is a controlled electromechanical system designed to convert the electrical power entering the created system into mechanical action. Or by using the same physical phenomena back to from mechanical power to electrical power in order to fully control this process.
However, such a definition is more correlated with modern electric drives, which are not only one device, but are also a whole set of many electric machines, apparatuses and control systems. In practical use and actual machines, the main consuming element in 60% of cases is the main consumer of incoming energy and almost always the main source of mechanical energy.

If we turn to the documentary definitions of this type of devices, according to GOST R 5036992, an electric drive is an electromechanical system consisting of electric power converters, electromechanical and mechanical converters, control and information devices, as well as devices interfacing with external electrical, mechanical, control and information systems. Each of them aims to set in motion the used organs of the working machine and thus control this movement in order to implement the entire technological process being carried out.
Here it is also worth paying attention to some division, namely the fact that from the legal definition, according to GOST, the executive body is not part of the device itself, however, in other authoritative sources, textbooks, monographs and others, the active part is part of the electric drive. At first, this division may seem really absurd, but in fact, all this is due to the fact that when designing an electric drive, it is necessary to take into account the mechanical load on the motor shaft, which in turn is determined by the executive body, that is, in this case, 2 devices are obtained.
