Today, in conditions of given the high demands for reliability and uninterrupted operation of equipment, electric machines are used in important and even critical technological processes, where their failure can lead to serious consequences, including production downtime, material losses, or even safety hazards. Diagnostic systems enable the timely detection of potential faults, which helps prevent emergency situations and significantly reduces costs associated with unforeseen repairs.
Moreover, with the advancement of technology, the design of electric machines is becoming increasingly complex, necessitating the implementation of more precise monitoring methods. Such diagnostics not only help prevent emergency situations but also extend the service life of equipment. Additionally, the timely detection of defects helps maintain high energy efficiency in machines, which is crucial for reducing energy costs and minimizing the negative environmental impact.
Integrating diagnostic systems into the overall automated infrastructure allows for real-time monitoring and more accurate forecasting of potential failures. These approaches reduce the risk of accidents, improve the efficiency of production process management, and ensure safety. In the context of the transition to Industry 4.0 and the widespread use of digital technologies, such systems have become an indispensable element for ensuring the stable and safe operation of rotating electric machines, which is critical for modern industrial enterprises. They also allow for a significant reduction in the energy intensity of production processes by extending the operational life of primary production assets.
The work proposes diagnostic indexes for detecting bearing defects in induction motors, theoretically justifying the use of the Hilbert transform for current-based bearing defect diagnostics, and demonstrating that the spectrum of the current envelope waveform should be plotted on a linear scale.

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.
