Abstract

It is seen that the use of wind energy as a renewable energy source in the world has increased recently. In addition to this, power plants are established for the production of high power electricity and the energy produced is given to the grid. However, in a region far from the urban area, electrical energy can be produced at small power levels. Radial flux permanent magnet alternators are the most widely used to generate electrical energy at small powers. Therefore, in this study, the effect on the efficiency of the materials used in radial flux permanent magnet alternators was investigated. Time savings can be achieved by analyzing the alternators used for the energy to be produced. The analyzes taken from the program contribute to the studies and may cause small deviations in real applications. In our study, considering the B-H characteristics of ferromagnetic materials, the effects of variable stator, rotor and magnet materials on the output performance were examined and comparisons were made by choosing the configuration with the best efficiency as a result of the optimization made. According to the graphical results obtained, time and cost savings were achieved.
