Magnet Rotor Wind Turbines : Transforming Wind Energy into Electricity
Table of Contents
Wind Turbines and How They Work
Wind turbines are like big windmills. When the wind blows, the big blades go round and round. This makes a part inside, called a rotor, spin. This rotor has magnets. These are not just any magnets, they are super strong Neodymium magnets!
- Core Parts:
- Rotor: The spinning part.
- Stator: The part that stays still.
- NdFeB permanent magnets: Super strong magnets!
- Power parts: Make the power go to your house.
When the rotor spins, it makes magnetic flux. This is like a magic magnetic field. This field makes power. This is called electromagnetic induction. It’s how we turn wind energy into electricity! We then change this power from AC to DC so you can use it at home.
Why We Use NdFeB Magnets
- Super Strong: NdFeB magnets are very strong. They can generate a larger magnetic field, or magnetic flux density than other permanent magnets. This means we can make wind turbines smaller and still make lots of power! This is called, Power density enhancement.
- Don’t Rust: These magnets are very durable because of their special magnet coating. They don’t rust easily, even near the sea!
- Last a Long Time, Even When Hot: They stay strong even when it’s very hot. That’s good for wind turbines that work for 20 years or more. And they are great for high-temperature performance.
Good Things About NdFeB Magnet Rotors
These special magnet rotors make wind turbines much better:
- More Power!: They make about 30% more power than old wind turbines!
- Less Fixing: These wind turbines don’t have a gearbox. That means less fixing. This makes them great for harsh, humid climates, and offshore wind installations.
- Last a Long Time: They can work for over 20 years! These strong neodymium magnets don’t get weak fast.
| Good Thing | How Much Better? |
|---|---|
| More Power | 30% |
| Less Fixing | Saves 20% on costs! |
| Long Life | Works for 20+ years |
Big Wind Turbines Use NdFeB Magnets
Big companies like Siemens Gamesa use these magnets. Their big Haliade-X wind turbine makes lots of power. It uses NdFeB magnets to make up to 14 MW (megawatts) of power. That’s enough for many homes, and an example of wind farm scalability! Goldwind’s wind turbine, the GW-16MW (offshore) model, uses NdFeB magnets to make enough power for a big neighborhood, more than 80,000 homes. ^5 The Vestas V236-15.0 MW Turbine in Denmark uses NdFeB.
| Company | Wind Turbine | Power | Uses NdFeB? |
|---|---|---|---|
| Siemens | Haliade-X | 14 MW | Yes! |
| Vestas | V236 -15.0 MW | 15 MW | Yes! |
| Goldwind | GW-16MW | 16 MW | Yes! |
What to Think About When Making Magnets for Wind Turbines.
These magnets from our NdFeB Magnets Factory are special. Here is why:
- Strong or Super Strong: We have N42, N52, and even stronger magnet grades. Choose the right one for your wind turbine!
- No Rust: We put a special coat on them. It keeps them safe from water and corrosion.
- Avoid: Too much heat or bumping can make them weak.
Using NdFeB Magnets in other systems
The features of Neodymium magnets that are valuable to the functionality of wind power applications are transferable to other industries.
These magnets are not just for wind turbines. The special features that are valuable for wind turbines, like being strong, corrosion resistant and heat resistant, are also just as valubale in other industries and systems. You can find them in:
- Medical Devices: magnets for medical, Magnetic Resonance Imaging commonly known as MRI.
- Aerospace: Aerospace engines and Electric Propulsion Systems.
- Cars:: Electric Vehicles (EVs) and Hybrid Vehicles.
- Phones and computers:Data Storage
Industrial Motors :Stanford Magnets
Choosing a Magnet Maker
The Right Paperwork: Make sure they have good papers, like ISO.
- Make it Your Way: Can they make magnets just how you want them?
- Help You: Do they know about wind turbines?
We at Customized NdFeB Magnets have been making NdFeB magnets for many years. We can do it all!

Keeping Earth Clean Too : Recycling
We try to help keep the Earth clean. We can recycle old magnets. To extract the valuable properties we use special processes. This includes, sintered magnet production, and magnetic shielding. This helps us use less new stuff from the ground. We can recycle about 90% of an NdFeB magnet!
Questions You Might Have
Can we use other magnets, like ferrite magnets?
Do we get our money back if we use these magnets?
Do we need a gearbox when using these magnets?
Let’s Make Power Together!
NdFeB magnets are changing how we make power from the wind. They are strong, last long, and help make lots of power!, Samarium cobalt alternatives are available, but don’t perform as well. We, as a Custom Neodymium Magnets maker, can help you. We know all about magnets for wind turbines.
