Magnets play an important role in the renewable energy market.?Magnetic materials ?can provide different solutions in?wind energy, tidal energy fields?.By using magnets and corresponding solutions, you can reduce or even eliminate gearboxes in wind turbines.The working environment of wind turbines is very bad and must be able to withstand heat, cold, wind, humidity and even salt fog tests.
The global wind turbine market have forced manufacturers to reduce manufacturing costs in recent years, improve efficiency, and create strong design capabilities for continuous services.The power conversion efficiency of wind turbines and electric generators can be improved by using suitable permanent magnet materials in wind turbines.In addition, selecting the right magnetic material and manufacturing it to the right specifications ensures that it is resistant to high temperature degaussing.
The next generation of wind turbines is being studied, using permanent magnet generators and axial flux couplers.The overall purpose of the design is to improve efficiency by reducing friction.?Magnetic couplers are currently used in many applications, but their greater potential is still being explored. ?Our?high quality neodymium magnets are being used in large commercial wind turbines to ensure high energy efficiency and good reliability for the entire generator system.
