Wind turbines working environment is very bad, it must be able to withstand heat, cold, wind, humidity and even salt spray test. Design life of the wind turbine is generally two years. At present, both small wind turbine or a megawatt-class wind turbines are mostly optional permanent magnet NdFeB magnets, therefore, requires wind turbine magnet has good temperature stability, corrosion resistance, and high uniformity reliability.
The recent explosion of the wind turbine market across the globe has forced manufacturers into reducing manufacturing costs, improving efficiencies, and creating robust designs that do not require constant service. Using a properly designed permanent magnet within the wind turbine generator will improve efficiencies in the conversion of wind power to electrical power immensely over induction, or wire wound, generators. Also, selecting the correct magnetic material and manufacturing it to the proper specifications will ensure that it can be resistant to demagnetization due to high temperatures.
The next generation of wind turbines are currently being researched which use permanent magnet generators and axial flux couplings, which use permanent magnets as a coupling. The overall purpose of this design is to increase efficiency by reducing friction. Magnetic couplings are currently used in many applications, but this is a new on that is being explored and has great possibilities. AO Magnet electronic provide wind turbine magnet - high quality neodymium magnets used in large scale in commercial wind turbines to ensure high energy-efficiency and good reliability for the whole generator systems.
