The article is devoted to the theoretical substantiation of energy-efficient operating modes of technological machines of the agro-industrial complex in the conditions of the need to increase productivity, reduce specific energy costs and ensure the stability of technological processes. The relevance of the study is due to the increase in the cost of energy resources, the need to reduce operating costs and increase the resource efficiency of machines and equipment. A significant part of technological machines is operated in nominal modes, which do not always correspond to the actual load, properties of raw materials and conditions of the operation, which causes excessive energy costs.
A theoretical and methodological approach to determining energy-efficient modes of operation of technological machines has been formed based on establishing the relationship between structural, kinematic, power, technological and energy parameters. A technological machine is considered as an energy-technological system in which the drive, working bodies, processed material and the external environment interact. The main components of the energy balance have been determined and a system of interrelated parameters has been proposed, including productivity, rotation frequency, torque, drive power, efficiency and specific energy consumption.
The use of specific energy consumption as one of the main criteria for the efficiency of a technological machine is theoretically justified. It is established that the dependence of energy consumption on productivity and operating parameters is nonlinear and is characterized by the region of rational modes. Under insufficient load, the proportion of idle losses increases, while excessive load causes an increase in power resistance, mechanical losses and energy consumption. The proposed approach creates a theoretical basis for determining the optimal operating modes of technological machines and further development of adaptive control systems.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
