Comparative investigation of the effects of litz wire usage on the energy efficiency, thermal and magnetic performance of i̇nduction motor windings

This study comprehensively examines the impact of using Litz wire on the performance parameters of asynchronous motor windings instead of traditional copper wire, aiming to minimize the energy losses caused by the skin and proximity effects observed in high-frequency applications. In this study, fundamental parameters—such as the differences in the electrical properties of the wire types used in motor windings, magnetic field distribution, and frequency-dependent resistance values—were analyzed in detail through models and simulations developed using Matlab. In particular, the resistance increases that occur due to the skin effect and proximity effect observed in high-frequency asynchronous motor applications exacerbate the issues associated with conventional copper wire usage and reduce energy efficiency. Calculations and comparisons regarding how Litz wire can minimize these adverse effects have demonstrated that energy losses can be significantly reduced. Additionally, the effects of different wire configurations on motor dynamics were examined in detail from the perspectives of performance and thermal behavior, thereby revealing that the use of Litz wire not only increases energy efficiency but also extends motor life and reduces maintenance costs. These findings emphasize the importance of adopting alternative wire technologies in the design and production processes of asynchronous motors in the industry. Furthermore, the results obtained provide new perspectives for further research and serve as a valuable reference for experimental applications and prototype development studies. The use of Litz wire in asynchronous motor windings offers significant improvements in performance, energy efficiency, and longevity, presenting considerable potential for modern electric motor technologies.
