Wind Turbine Magnet
Wind turbines convert wind energy into electrical energy, and magnets play a crucial role in this process. The type of magnet commonly used in wind turbines is the Neodymium Iron Boron (NdFeB) magnet, also known as a neodymium magnet.

Where Are Our Wind Turbine Neodymium Magnet Used in Neodymium Wind Turbine?
Permanent Magnet Turbine

Custom neodymium magnets are used in the generator of a wind turbine. They are a key component in the production of the turbine’s electricity. The wind turbine neodymium magnet is placed around the rotor, which is turned by the wind’s energy. As the rotor spins, the wind magnet powered turbine creates a magnetic field that generates electricity. The stronger the magnets, the more electricity can be produced. This is why neodymium magnets, which are incredibly strong for their size, are commonly used.

Core Technologies of Our Custom NdFeB Magnets
Neodymium magnets are made from a combination of neodymium, iron, boron and other ingredients. These magnets are known for their high magnetic properties and are widely used in various industries. The core technologies involved in the production of custom NdFeB magnets include:

1. Melting: The first step in the production of NdFeB magnets is melting and alloying the raw materials. Neodymium, iron, and boron are combined in precise ratios and melted in a vacuum induction furnace. This process ensures the alloy's homogeneity and eliminates impurities.

2. Hydrogen decrepitation and Jet milling: Once the castings are formed, they will be pulverized into particles in several microns. The powder size is critical in determining the magnetic properties of the final magnet.

3. Pressing and Sintering: The particles are pressed into a compact shape through a hydraulic press. The pressing process is carefully controlled to achieve the desired magnetic properties. The compacted powder is then sintered at high temperatures in a carefully controlled atmosphere to bond the particles together and form a solid magnet.

4. Inspection: Inspection technology is crucial for NdFeB magnets, ensuring their quality, performance, and safety, thus underpinning our core technologies.

5. Machining and Shaping: After sintering, the magnet undergoes further machining and shaping processes to achieve the final desired shape and dimensions. This may involve cutting, grinding, drilling, and surface treatments to enhance the magnet's performance and protect it from corrosion.

6. Optional GBD process: GBD is currently one of Ketian's significant developing direction, with multiple process routes. This type of magnet is widely used in fields like main drive motors for new energy vehicles, air conditioning compressors, and intelligent robots. It is customizable and selectable according to customer needs.

7. Magnetization: The final step in manufacturing custom NdFeB magnets is magnetization. A strong magnetic field is applied to align the magnetic domains within the magnet, maximizing its magnetic strength and performance.

In addition to these core technologies, there are several other important considerations in the production of custom NdFeB magnets, such as quality control, surface treatment, and magnet assembly. These technologies ensure the production of high-quality, high-performance NdFeB magnets tailored to specific customer requirements.

3. Wide Range of Temperature Stability:

NdFeB magnets have excellent temperature stability, allowing them to perform reliably in a wide range of operating temperatures. They have a high Curie temperature (the temperature at which they lose their magnetism) and can withstand both high and low temperature extremes.

4. Versatility:

NdFeB magnets can be custom-made to suit specific applications. They can be manufactured in various shapes, sizes, and grades to meet specific magnetic requirements. This versatility makes them suitable for a wide range of industries, including automotive, electronics, medical, energy, and more.

5. Cost-Effective:

NdFeB magnets offer a high magnetic strength-to-cost ratio, making them a cost-effective choice for many applications. Despite their high performance, they are relatively affordable compared to other magnet materials.

6. Resistance to Demagnetization:

NdFeB magnets have a high resistance to demagnetization, meaning they retain their magnetic properties over time even in challenging operating conditions. This makes them suitable for long-term applications that require stable magnetism.

7. Wide Range of Applications:

NdFeB magnets are used in a wide range of applications, including motors, generators, magnetic separators, magnetic resonance imaging (MRI) machines, loudspeakers, magnetic lifters, wind turbines, and more.
