New V.A.W.T. design

[Energy Creator]

Hello all,

I am building on a V.A.W.T. and I like to share my design with all of you.
I don’t know if it’s gone work? But it’s the idea that the blades will automatically adjust by high wind speeds, so your generator will never turn to fast.


If the VAWT spins to fast the centrifugal forges will lift the weight and the blades change its position , so it catch less wind or will even brake.
With the weight you can set the maximum RPM for your generator.


The prototype is made of Polyether and steal.
The directional scoops of the outer ring are not installed yet.
But you se the groves where they gone be placed.


The directional scoops of the outer ring will direct the wind in to the blades.
The back coming blades are not pushing in to the wind.


Whit this setup I hope to collect more wind, so the VAWT will turn faster by low winds.


The structure is like 3 doors you can open for easy maintenance


The Blade


The Blade design is just a gush, no idea if it’s working.
Therefore also the open structure of the VAWT so we can chance the blades easily.

This design is just a idea!
I don’t know if it will work?

There is only one way to find out.
Just build it!

I hope you all like the design?
If you se some flaws , please tell me!


Cheers

Wow very interesting! I have not seen this design before, and can give no advice at this time, but i really like the concept!

Hi Energy
This is a very nice design. I built a similar unit many years ago but couldn't get enough power from it so the wife made me take it down so she could expand her garden and I went on to other ventures. The key I found was the bearings...what kind are you using?
I also used vents to direct the wind directly into the windmill itself. I know I have some old pics around here. If I fnd them I can post them and show you

Hi,
it might work with something like a centrifugal clutch, where the clutch turn the Angel from the blades.
But else i think its the best Idea to have on the Blades one smooth Side and one Side with Hooks where you can catch more Wind.

I use for vertical bearings magnets when possible.

Take a pole put a magnet on top, put a slightly over-sized pipe over it, with the top end capped with a magnet in repulsion configuration

Or depending on the design;

Use two ring magnets at the bottom.
Or both.

Either way, it makes a simple friction-less bearing for the vertical forces carrying the weight.

Now for the horizontal forces it could be interesting to combine the generator and the magnet bearing. Not sure if that is possible here is a concept:

Inner ring attached to VAWT, VAWT rests on disc. The magnets from inner ring and outer ring repel so, no friction and nothing touches.
The inner ring rotates, and the coils are stationary.

But now put coils in between, and you have a generating friction-less bearing.

It might be even possible to spin the outer ring mechanical as well... More power! ;-)

Hi Cherryman,
That is what I use. Two neodynium ring magnets with the North facing each other. I use a copper pipe for shaft so the magnets aren't attracted to it. To hold it in place I use wash down bearings these things last forever

Uhmw-Pe Bearing - Mounted Bearings - Bearings - 1F560 : Grainger Industrial Supply

In fact they operated for my windmill for 5 years and I use them now for my current experiments ....still in service

An Idea?

SInce you have already created a 360 venturi, maybe you can increase air intake to more areas of your vanes by ducting air as well? This may also serve to stop vanes on the back of the air flow from beating?

Thanks all!

Hi Bizzy,
Yes I like to se those pictures.
I use now normal bearings for the core with the blades.
It was just to test if the windbreak will work, don’t now what they gone do under a working condition? But I gone try the magnet thing you and Cherryman suggest.

Hi Joit
I really don’t know what the right blade will be?
Gone make it so that the blades are easily replaceable.
So we can test all kinds of blade models.

Hi Cherryman
Thanks for the information.
I really like these friction-less bearing idea!
I saw it on youtube ones, but all forgotten about it.
I going to use this or a hybrid of it?
It may not move sideways, be course I like to make 2 generator rings like this instead of a bulky generator.

How bigger the coil ring diameter how faster the magnet move by the copper wire by low rpm.
Will it work? Don’t know, just gone build it anyway.

Hi Rubberband
Thanks for the interesting suggestion, gone look in to it!
Gone make the prototype so that I can play around with it and test all kind of ideas with it.

I really like the ideas of all of you!
I gone put it in to the design, thanks

Cheers

Hoi Brian,

PS. Begrjp ik nou goed dat je de generator in de ring wil proberen???
Cool! Hou rekening met vibraties, dat je geen oneven "gaten" krijgt in je magnetisch veld. (Al hoef ik jou niets uit te leggen over magneten geloof ik )


Succes Brian, maak er iets moois van, wie weet kom ik een keer kijken!

Proost!

[Energy Creator]

Hello Cherryman

Ja dat heb je goed gezien, moet inderdaad wel stevig worden!
Mag zeker geen speling in zitten.
Als je een keer wilt komen kijken ben je van harte welkom.
De koffie staat voor je klaar, ik zit in Gouda.

For those who cant read this, I invited Cherryman to drink some cold Beers and talk about the VAWT.

Cheers

my VAWT

Here are some of the picture of the VAWT we built a few years ago....

Other Idea

A contrary idea. What if the vawt is put in a ring of flaps that adjust themselves to open and close for control of wind.

[Bizzy]

Vawm

Good morning
Here are too short videos showing the VAWM moving


in 4 mph wind
VAWM at 4mph.AVI - YouTube

in a 10 mph wind

VAWM at 10mph.AVI - YouTube

Hi Guruji
If you use vents like I did you wouldn't need flaps .Check out my videos on the previous posting

hi Guruji

adjustable flaps on the outer ring for wind control is a good idea but then I need some mechanism with a motor and a wind speed sensor and properly a computer with a stepper card or relay card to control it?

That’s why I try to control it mechanically by the centrifugal forges, but don’t know if it works.
The centrifugal forges push the blades outwards but the directed wind is pushing it inwards again??? Mmm…..
But yes if this is not working, I go for the adjustable flaps on the outer ring.

Thanks
Cheers
