The article is devoted to the study of the influence of the geometric parameters of the conductor and insulation on the durability of the insulation systems of electrical machines. In modern industrial conditions, the reliability and durability of electrical machines play a key role, since the efficiency of many technological processes depends on their stable operation. Optimization of the design of windings and insulation is becoming an important task aimed at improving performance and reducing maintenance costs.
The paper examines approaches to optimizing insulation systems taking into account changes in the geometric parameters of the conductor and the insulation layer. The analysis provided allows us to assess the impact of such changes on the main properties of the insulation, including its resistance to electrochemical and mechanical effects. Particular attention is paid to the selection of design solutions that can be used to improve the reliability of electrical machines under high load conditions.
The research methodology includes both theoretical modeling and experimental tests to assess the properties of insulating materials and their behavior under various operating conditions.
The work also focuses on the economic aspects of increasing the durability of insulation systems. Optimizing the design not only increases the service life of electrical machines, but also helps reduce costs associated with their operation, repair, and maintenance. This is of particular importance for industries where equipment operates under intense loads and requires minimal downtime.
The article also emphasizes the importance of an integrated approach to the design of insulation systems, which includes not only the selection of suitable materials, but also their optimal combination with the design parameters of the windings. This approach improves the performance characteristics of electrical machines, increasing their service life and reducing the likelihood of failures.
The findings and practical recommendations can be used in designing new electrical machines and upgrading existing systems. This is especially relevant for industrial sectors that require high reliability of equipment and minimization of maintenance costs. Thus, the work contributes to the development of technologies for designing durable and efficient insulation systems for electrical machines in general.
