The study aims to analyze methods and electromechanical equipment used in the production of hardware products utilizing wire drawing mills. The research focuses on improving the efficiency of the wire drawing process by optimizing technological parameters and modernizing the electric drive system. The study investigates the most effective wire drawing machines for medium-diameter wire (1.8–3.0 mm). The research highlights that single-pass drawing machines are the most promising due to their ability to enhance the efficiency of the drawing process. This is achieved by optimizing energy-force parameters and increasing the drawing speed. Additionally, mathematical modeling of the wire drawing machine's electric drive system was performed to evaluate its performance under various operational modes. It has been established that improving the efficiency of the wire drawing process can be achieved through the modernization of existing electric drive systems. This modernization leads to a significant increase in the overall efficiency of the drawing process. The study also proves that an increase in drawing speed is possible by implementing a more advanced electric drive control system. The optimization of the energy-force parameters contributes to a reduction in energy consumption while maintaining high productivity. Originality: The research demonstrates that an electric drive system based on a frequency converter and an asynchronous motor is economically advantageous as the main drive for a wire drawing machine. The proposed approach ensures improved energy efficiency, reliability, and precision in speed control during the wire drawing process. The study also confirms that the developed control principle allows for a stable drawing speed with minimal deviation, ensuring high process accuracy. The analysis of the operating modes of the wire drawing machine’s electric drive using a mathematical model confirmed that the developed control method ensures precise speed regulation with an error that does not exceed the predefined limit. The implementation of the proposed control system leads to improved overall process stability and compliance with technological requirements. Additionally, the findings of this study can be applied to industrial-scale wire production, contributing to increased automation and energy efficiency. Thus, the proposed modernization of the electric drive system and optimization of energy-force parameters lead to improved efficiency, reliability, and precision of the wire drawing process. The use of a frequency converter–asynchronous motor system ensures economic benefits and enhances the overall performance of wire drawing machines. The developed approach meets all technological process requirements across different operating modes, making it highly suitable for industrial applications.
