Design and Optimization of Axial Flux Permanent Magnet Generators with the use of Evolutionary Algorithms for Grid-Tied small Wind Turbines in Rural Electrification Applications
This work provides a study of the optimization aspects of coreless axial flux permanent magnet generators at a range of nominal power from 3 to 6 kW for wind power applications. Their basic characteristics are the ease of construction and the possibility for larger pole numbers in the rotor [1]. An introduction on the initial design and on the optimization algorithms that are applied is presented, while the construction constraints and the optimization parameters are presented as well. The results and the correlation between the different parameters are analyzed. Also a comparison for magnet grades N40 and N45 is included. These generators can be designed either for direct battery charging or for grid connection as micro sources in microgrids [2] and they can be used for the electrification for rural communities in developing countries, as 1/3 of the global population has no access to electricity [3].
