Design and construction of an optimum high power radial flux direct-drive PM generator for wind applications

This paper discusses the development of a high power Radial flux direct-drive PM generator for wind applications. A low-speed radial-flux permanent-electrical with new magnet (PM) generator topology was built and tested. The designed, optimized and constructed. This paper presents the design of a 20 kW permanent magnet generator using Neodymium-Iron-Boron. The finite element technique (FET) is used for detailed characteristics and final adjustments. The design was carried out with high-energy NdFeB built and tested. The genetic algorithm is used to optimize machine structure and to achieve high power density and efficiency. The generator operation is investigated in both simulation and implementation. The great agreement between simulation and implementation results proves the validity of this generator structure.
