My Wind power Project

This project is pretty well built from scratch.  I even carved the blades themselves, I tell ya, what a learning curve!  Please forgive my lack of instructions on this site, I am slowly trying to get my projects onto the web, and details.  I spend too much time building them and I don't update my site as often as I should, but eventually I will get all the instructions and reports done on my website, stay tuned... 

The windmill blade fell off and stuck into the ground on Sept 2005.  I am not sure why, but the bolts that hold the rim, worked there way through and the blades came off.  So now I think its a good time to re-think everything.  Boy it was stuck, deep, in the ground.  It took a bit to work it out as it was sunk about 2 feet.  It has been raining quite a bit and the ground was really soft.

I am going to retry my little windmills.  I have so many extra blades for them, and with extended blades, they will do better.  I am going to buy a 24volt stator for the PMG and see if it will work better.  If I can keep the windmill loaded via always charging they should not produce noise like they have in the past.  I suspect that it was mostly due to the speed they had to turn in order to start producing power, but if I can lower the cut-in speed, I think they will work well.

The one major advantage with this is the blades are optimum, and another advantage is the whole unit will be lighter, and easier to maintain.  No more tires that will wear out.  Mind you the last tire, and setup was doing well, and has been running for the longest time so far without burning up the tire.

I think also now that the tower is wired for 3-phase the little windmill will also have and advantage with this.

It will take a couple of weeks to get another stator, so I will post further testing as soon as I can.  If I can get 40 + amps out of the small unit, I will be happy!

October 2005

Got another stator.  This one had 6 winding each coil, and from testing it was not enough. 

So I wound one with 15 winding each coil.  One the drill press turning at 600rpm it was at 13.65 volts DC after the rectifier.

I have found a fairly easy way to wind the stators.  I will post pictures and instructions as soon as I upload from my camera.

Testing is good, but I think I can even get away with more windings.  It still takes quite a few RPM's before it starts to charge my batteries, and also it tends to spin in the harder winds to a point it "sings".  It is a very weird noise from the blades tapering out of the wind.  I figure this is a just a fluke, and the next time I change the cut-in point it will get rid of this noise as it will maintain a load on the blades.

Other than the over-speed making noise, this unit is abnormally quiet.

Well I tried a 24 volt stator.  It only had six windings per coil.  Very strange, correct me if I am wrong, but you would think in an 10si Delco alternator, from one being 12Vdc with 4 winding, you would have to double the winding to achieve 24Vdc?  It had only six!

only pictures, have to work on these pages - Under Construction

 

This has been the average wind in my area.  I live in a good area for wind power, its always windy.  Very few days out of the year have no wind!
