Hello, its bin a long time.

Finely the wind direction scoops are mounted on the V.A.W.T.



Now we have to make the rotor and a cool generator what fits perfectly by the V.A.W.T.

I was building on a new generator design whit the same winding principle.
Only it will become a big ring.


A ring generator?

I don’t know when this project will be finished?

In 2 weeks I am going to Brazil for 6 months to create some energy systems in the middle of no ware on top of a mountain for generating energy for a few homes.

So, my next movies or updates will com from Brazil.

Brazil??.... Yeehaaa Party Time!!

Hi, congratulations and safe journey. What is the stator resistance?
just because your a GURU or forum administer does not mean your always correct :)

Hi, the coil ring stays stationary and the magnates are going to spin.
The rotor will come on the inside.
I don’t know the resistance, its already in the container for shipment….. forgot to measure??

But I have made a smaller one for testing!
It’s a Ring generator, diameter 45 cm , 6 phases 2,2 ohms a phase But connected to 3 phases with 4,4 ohms a phase.
Wire used 0,7mm



The coil is embedded in polyether.
I also embedded a temperature sensor for further testing.

I have made a quick test movie of the ring generator, its on YouTube.
Ring generator

I will try to make a descent test bench for descent testing before I’m of to Brazil.

Cheers to you all!

your ring stator is beautiful work Brian.
that's a very nice casting.
i have been planing one for this winter .
but it will be two phase with overlapping coils.
and a mag rotor on both the outside and inside.

consider winding a layer of silicone steel wire around the outside of your stator to give a flux return path
it should pull the flux through the copper.
