The issue of creating low–voltage low–power electromagnets with increased reliability for automation systems in machines of the agro–industrial complex is considered.
A technique is used to calculate the parameters of the electromagnet from the condition that the first cascade of the unit be operational. In addition, experimental methods for determining the characteristics of prototypes of electromagnets are used.
The analysis of the application of modern aggregates with electrical control in various machines of the agro–industrial complex is carried out. An important parameter of electromagnets are their traction characteristics, which determine the operation of the electromagnet and, accordingly, characterize the reliability of the entire system. Based on operating conditions, to provide mechanical reliability and simplicity of design, it is proposed to use armored–type electromagnets with an embedded core.
The effect on the power characteristics of the structural design of electromagnets, namely the non–magnetic insertion in the steel coil of the coil, is assessed. The parameters of this element significantly affect the magnetic field and, accordingly, the power characteristics of the electromagnets. Schemes of magnetic fluxes in electromagnet are considered with different arrangement of a non–magnetic insert. When calculating the parameters of the winding of the coil, the basic requirements for it were taken into account, namely the specified critical force, the critical gap, the size of the armature of the electromagnet, the cross section of the magnetic circuit, and the magnetomotive force.
A special stand was prepared for experimental research, on which experimental measurements of the traction characteristics of prototypes of electromagnets were made. A family of traction characteristics of these electromagnets is constructed at different supply voltages.

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.
The journal consistently adheres to the principles of open science. All published materials are distributed under the Creative Commons Attribution 4.0 International License (CC BY 4.0), ensuring open access to research results provided proper attribution to the authors and the original publication is maintained.
At present, Technology, energy, agriculture transport AIC is an authoritative professional scientific journal (Category B), providing a platform for the publication of fundamental and applied research results, promoting the integration of education, science, and industry, and contributing to the advancement of engineering and technological support of the agro-industrial complex of Ukraine.
