China Neodymium And Ferrite Magnets Manufacturer & Supplier 
We often see some big windmills on some high mountains, this is what we are talking about today's wind turbine generator, the magnet is one of its core components, plays a very critical role, about the role of the magnet in the wind turbine generator, shape, material and so on the following article will be introduced.
Several types of magnets in wind turbine generators
There are 3 main types, which are sintered neodymium, samarium cobalt and ferrite. The main one is sintered neodymium magnet, because of its super strong magnetism, it is basically chosen in some large wind turbine generators, common grades such as N38SH, N40H, N42SH, N45UH and so on.
Role of Magnets in Wind Turbines
Generating a magnetic field is one of the main roles of magnets, and in wind turbines as well, permanent magnets generate a fixed magnetic field in the rotor, and when the wind-driven blades drive the rotor to rotate, the magnetic field cuts through the stator coils, generating electricity through electromagnetic induction.
High performance grade arc neodymium wind turbine magnets
What shape is the magnet in a wind turbine generator?
There are also 3 main types, which are curved, rectangular, and wedge shape.
Suggestions for magnet selection;
For high power onshore wind turbines, NdFeB can be selected to balance high flux density and temperature resistance. Offshore wind turbines can consider SmCo or corrosion-resistant coating NdFeB. For small wind turbines, ferrite can be chosen to reduce costs.
High power onshore wind turbines can be made of NdFeb material, which balances high magnetic flux density and temperature resistance. The outer rotor structure should preferably use arc-shaped magnets to reduce magnetic field unevenness. High power generators can use wedge-shaped shapes to reduce energy loss. Offshore wind turbines can consider SmCo or corrosion-resistant coating NdFeB. For small wind turbines, ferrite materials can be chosen to reduce costs.
