Would you like to build your own wind turbine? We will introduce you to two projects from customers who used our neodymium magnets to build wind generators. The first project is from an individual who created a DIY wind turbine for personal use. The second project comes from a student who built his own wind generator as part of a diploma project.

Build your own affordable wind generatorI built a small wind generator, setting the following goals for myself: lightweight, relatively simple assembly and low material costs. Details of the construction can be found in the YouTube video at the bottom of the page (only in French, but it should be easy to follow for speakers of other languages as well).
Now it was time to use your strong magnets. Previously, I had tried using weaker magnets but with less than satisfactory results. On top of that, your magnets are priced fairly, so they did not jeopardise my budget :-).
I glued 12 of your disc magnets type S-20-10-N onto the metal disc in regular intervals using a strong adhesive. All of the magnets needed to be oriented the same way.
Now I only needed the windmill itself. It has three rotor blades made of acrylic glass, which I tapered and gave a bevel of 20 degrees. The entire windmill has a diameter of 1,5 metres.
- Total weight: about 8 kg
- Voltage: 18 volts at wind speeds of 30 km/h, at 8 km/h already 12 volts
- Total cost: less than 100 euros thanks to inexpensive materials
Here is the YouTube video with explanatory speech bubbles.
Building a wind generator as a diploma project
Addition from our customer Tommi Ollikainen in Kuopio (Finland):
I wanted to build a power generator for my windmill. The windmill has a rotor with an impressive 3,72 meters diameter.
I placed 16 Q-40-20-10-N block magnets on each of two round steel plates. The magnets were placed on the outer edge with the poles alternately positioned (north-south-north). The direction of the magnets on the first plate should mirror exactly the placement of the magnets on the other plate so that the magnets attract to each other.
Tommi completed this project as part of his diploma thesis in electrical engineering. His thesis studied the possibilities and wind conditions required for the use of wind-powered generators in Finland. The generator should have minimal investment costs (maximum 1000 Euro). The current prototype delivers enough energy to power a hunting cabin in Kortemäki, Vieremä in Finland.
