Test 01 - Small VAWT

Visit calebeng.weebly.com Just a test to see if the VAWT would spin in the wind. The blades are similar to a Lenz2 only with half the curve. Please forgive the camera angle; it was difficult to hold both the camera and the VAWT at the same time.

Why are the magnets mounted on the separate disks that are welded to the main assembly?

What material are the blades made of?

Thanks

@skyl4rk I used a magnetics FEA porgram ... FEMM 4.2 (free) and determined that I needed about 0.100" of steel backing the magnets. But I didn't want to use that heavy a gage through the entire part because of weight and cost (a lot of scrap) and the strength wasn't required, so instead, there are two layers of 18 GA steel to back up the magnets.

I'm guessing your main idea is to develop an inexpensive VAWT system for 3d world use. I like it, but the expensive part is making the electricity usable. Batteries, inverters, and safety systems all cost a lot of money, as you know. I suppose it needs to start with the actual energy, though. I'll continue to watch with interest. Good luck.

what is the 5 for 25 project? sounds very interesting

Looking good. Keep up the good work.

Hey

I like the 2 disks on top of each other so your blades are pretty stable and it makes it more easy to connect them.

I hope we will see more video's on this.

Great job

Greetings
