This paper examines the main requirements for the electric drive systems of a class of boring machines with digital program control. On this basis, a methodology for choice of the spindle drives is offered. The algorithm takes into account the specific features of the technological processes, the treated materials, the tools used and their wear, as well as the mechanical gear types. The experimental studies of the implemented electric drives for the spindle are presented and discussed. The research carried out and the results obtained can be used in the development of such drives for the studied class of machine tools.

The relevance of research is due to the increasing role of digital technologies for managing agricultural production on reclaimed lands in ensuring sustainable growth of agricultural production efficiency. The object of research is precision (precise) management of agricultural production. The subject is advanced technologies for the rapid formation and regulation of the reclamation regime of agroecosystems that meet the requirements of sustainable development of the crop production system of the domestic agro-industrial complex. The purpose of this work is to improve methodological and technological approaches to digitalization of technologies for managing the reclamation regime of the agroecosystem. the Scientific novelty of the work is to substantiate the functional orientation and list of priority tasks solved by the created digital systems, which required studying the specifics of applied technologies for managing agricultural production; determining the effective direction of improving automated management. The research was based on the analysis of normative-methodological and legal documents, literary sources, as well as personal developments of the author on the subject under consideration. Methods of comparative and system analysis and expert assessments were used in the work. Factors of competitiveness of economic entities implementing support of management decisions by digital systems are identified. Uncovered causes that reduce the effectiveness of the implementation of the digital control systems of agricultural production on reclaimed lands in the Russian agricultural sector Shows the priority approaches to the structure of control system of technological processes of agricultural production, emerging based on the integration of access to information for business processes of enterprise management. A list of priority tasks of automation of technological processes of reclamation agriculture has been developed. Priority requirements for improving digital technologies for managing the reclamation regime of agroecosystems in terms of information, technology and software are formulated. The proposed transformation of approaches to the creation and use of automated production process control systems (APCS) and General approaches to enterprise management (APCS) meets the requirements of the «Internet of things (IOT)», one of the newest trends in the evolution of modern Internet technologies. The technological process of precision management of agricultural production based on digital systems Maxim built into the management procedures of the hydroreclamation system, rationalized, with significantly increased efficiency transforms the interaction of producers and consumers, bringing them flexibility, organizing the exchange of information via the Internet.

The relevance of the study lies in the search for energy-saving technologies. So, at present, the most common type of electric drive in industry is asynchronous, most of which are unregulated. Replacing an unregulated electric drive with an adjustable one in various units can significantly reduce energy consumption, increase the life of the mechanical part of the drive and improve the quality of the adjustable process parameter. The replacement consists in installing an electronic frequency converter between the network and the motor of the device. This device changes the rotational speed of the motor rotor by changing the frequency and amplitude of the supply voltage. The most common are frequency converters with an intermediate DC link. Such devices are built on electronic keys, which are made on IGBT (Insulated Gate Bipolar Transistor) transistors. Using the NI Multisim14 software, a model was created to determine power savings during the implementation of VFD.The paper gives the rationale for the introduction of a frequency-controlled electric drive (VFD) to optimize technological processes in electrical complexes and systems, in particular, a complete analysis of the energy efficiency of VFD application in pumped water supply systems is presented as an example. The calculation of its economic efficiency for a particular installation is also given.

The paper analyzes the possibilities of improving the Russian policy of import substitution using the potential of the EAEU. A concrete analysis was carried out for the branches of the agro-industrial complex, where the greatest success was achieved in import substitution. There is a need for smart selective import substitution, the most important direction of which is the export-oriented one. This will improve the competitiveness of Russia and the EAEU as a whole in the global economy and will also promote the deepening of mutual ties of the EAEU countries. The main ways of solving this problem are shown.
