I 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 :-).
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
- Capacity: 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.
