Wind Turbine DIY Project for School - Steel Plate vs Non Magnetic Plate

In summary, the conversation discusses building a wind turbine for a school project using DIY methods. The turbine requires 6 or 9 coils with 8 or 12 magnets mounted on a steel plate for increased power. The question is raised if using a non-magnetic plate would be better. The conversation also includes a link to an example of a DIY turbine and speculation on the use of steel plates.

i don't know if i am in right part of forum.

i want to build some sort of wind turbine for a school project. all the diy project are 6 or 9 coils with 8 or 12 magnets. the coils are on non magnetic board and the magnets on steel plate.
why on steel, the steel plate increase the total power of generator, like concentrate the magnetic field? is not better to mount the magnets on non magnetic plate to?

I could see using smaller magnets and compensating by using steel plates to act as additional magnets. Not really sure though. Got a link to a DIY one?

this is an example. http://www.windenergy.nl/website/files/artikelen/AXIAL_FLUX_HowItWorks.pdf [Broken].
my q is if seel plate increase or no the power of the turbine

From the article it says the magnetic field lines are confined by the steel hub the magnets are attached to. This might be the reason. That and steel is strong and relatively cheap.

I would like to provide some insight on the use of steel plates versus non-magnetic plates in wind turbine DIY projects.

Firstly, it is important to understand the purpose of the steel plate in this project. The steel plate is used to create a magnetic circuit for the magnets, allowing them to be more efficient in generating electricity. This is because steel is a ferromagnetic material, meaning it can be magnetized and will retain its magnetism. This helps to concentrate and direct the magnetic field created by the magnets, resulting in a more powerful and efficient generator.

On the other hand, using a non-magnetic plate such as aluminum or plastic may not have the same effect. These materials are not ferromagnetic and therefore will not contribute to the magnetic circuit. This could result in a weaker magnetic field and lower power output from the generator.

In addition, using a non-magnetic plate may also introduce unwanted interference to the magnetic field, reducing its strength and efficiency. This is because non-magnetic materials can still interact with magnetic fields, causing disruptions and distortions.

In conclusion, while it may seem counterintuitive to use a steel plate in a DIY wind turbine project, it is actually the most effective choice for generating electricity. The steel plate helps to concentrate and direct the magnetic field, resulting in a more powerful and efficient generator.
 

1. What is the purpose of a wind turbine DIY project for school?

The purpose of a wind turbine DIY project for school is to teach students about renewable energy and how wind turbines work. It allows students to gain hands-on experience in building and designing a functioning wind turbine.

2. Why is steel plate often used in wind turbine DIY projects?

Steel plates are often used in wind turbine DIY projects because they are strong and durable, making them suitable for withstanding the high winds and extreme weather conditions that wind turbines are exposed to. Additionally, steel plates are readily available and relatively affordable.

3. What is the difference between a non-magnetic plate and a steel plate?

The main difference between a non-magnetic plate and a steel plate is that steel is a magnetic material, while non-magnetic materials do not have magnetic properties. Steel plates are typically made from iron and carbon, while non-magnetic plates can be made from a variety of materials such as aluminum, copper, or plastic.

4. How does the choice of plate affect the efficiency of a wind turbine?

The choice of plate can affect the efficiency of a wind turbine in several ways. A steel plate may be heavier and more durable, allowing it to withstand stronger winds and generate more energy. However, a non-magnetic plate may be lighter, causing less resistance and allowing the turbine to spin faster. Ultimately, the design and construction of the turbine will have a larger impact on efficiency than the choice of plate.

5. Are there any safety concerns when using steel plates in a wind turbine DIY project?

Yes, there are some safety concerns when using steel plates in a wind turbine DIY project. Steel plates can be sharp and heavy, so caution should be taken when handling them. It is important to wear protective gear, such as gloves and goggles, when cutting and shaping the plates. Additionally, the steel plates should be securely attached to the turbine to prevent any potential hazards from loose or flying pieces.
