Effect of silicon ratio and sheet thickness on energy efficiency of induction motor
Abstract
Electric machines consume a large portion of electricity in industry and daily life. To minimize energy consumption, it is necessary to increase the performance of electrical machines. There are three key factors influencing the energy efficiency of transformers and electric motors. Electrical steels, also known as silicon steel sheets, are widely used as core materials in electric motors, transformers, and generators. The silicon ratio of electrical steel has a crucial role in energy efficiency. In this study, a finite element model was used to observe the effect of silicon ratio and sheet thickness on motor efficiency. In the finite element model, M27, M36, and M43 core materials were employed in varying thicknesses (e.g., 0.36, 0.47, and 0.64). M43 silicon steel had the lowest electric motor efficiency, measuring 83.19%, whereas M27 silicon steel demonstrated the maximum efficiency, measuring 84.24%. An improvement in energy efficiency of 1.05% was found in the study's results. The results of the study indicated that motor efficiency could be increased by optimizing the thickness and silicon ratio of the silicon steel sheets.
