WIRING THE COILS IN 3 PHASES AXIAL FLUX GENERATORS

Picture of WIRING THE COILS IN 3 PHASES AXIAL FLUX GENERATORS
There are a lot of instructions in how to make an AXIAL FLUX GENERATORS, but what they are lacking is a clear explanation on HOW TO WIRE THE COILS. I know that because I have been researching about the theme, and it was a hard work.  When at last  I figured out how the COILS ARE WIRED, I made these schematic drawings, which I now share with all of you, specially those that like me do not know anything about electricity or electronics but are willing to learn and to make.  If you need to use these eschmas and drawings please feel free to use them, just give me the credits.  So they say a picture is worth a Thousand words.

If you enjoy this work or it helped you in any way, please value it.

I have specials thanks to a friend that was very inspiring to me, with his educational videos in YOUTUBE. 

MUDDY please keep smiling and the good work you do.

Step 1: The Beggining of the coils go here

Remember this is just an illustrative Schema of where each coil go.
The beggining of the coil is the end from which you began to wind your coil,
the ending of your coil is where you finished your winding..

Step 2: The ending of the lasts coils go here

hello good connections>

any idea how we can connect this to the bridge rectifier to get DC power

Hi Guzzi_Gerard,
Thanks for all the information you have sent me, I have enjoyed it and learned a lot from it.

You dont bother me when you write to me and send me all this information, and dont get me misunderstood that I underestimate the fact that the device is human powered, we need to do excersises and will make a nice devoce for many pepople.

About th Fisher & Paykel motor, yes it makes a fantastic generator, but in my country I dont know where to get that motor in particular. If there is any source that we can get them or buy them, please send me that information. I will aprreciate, because it has many advantages. It is alreadey made as a generator with the magnets and all allready in places.

You can also write to me at my mail: happy2think@gmail.com and I would appreciate having your mail too.

God Bless you

Yes, this youtube movie is human powered. But the Fisher & Paykel motor makes a fantastic generator with 1 Watt per rpm up to 1.8 kW! They are NASA-engineered, the latest versions are decogged, and can be changed to alternative voltages and currents with some effort.
What is so fantastic about 'pedal-power' video is the schemes he is displaying for different configurations. So for example, the fourth scheme is a configuration in which you at low windspeeds don't use all the coils (a too heavy load for the wind at that moment if all were used), so despite the low wind but because of the lighter load it will start to spin and generate at that lower windspeed.
When the wind gets stronger the other coils are connected and you'll get more power off the generator while keeping the voltage at the same level as well as the rpm's of you windrotor. It is possible to put two of those generators at one windmill (They can be lifted by ONE hand) and let them start to generate at different windspeeds. So controlling your load on the windmill, the voltage (RPM), and currents.
With two generators easily and robust 3,5 kW. With the possibility to get the mill rotating at low speed because of the first generator you only let a part get connected in (See scheme 4) and they are decogged. And the same can be done with the second generator, third....Even for breaking. That gives a fantastic possibility of controling the windturbine.
The F&P-motor/generator is very solid, very well engineered (NASA) and they can be purchased for very economic prices, about $25-40 dollars, because they were used in washing machines! Unbelievable. So, if some damage happens to the windturbine you can easily changes the generators. Serious, long-time small turbine builders are in love with this motor/generator.
Also take a look at the videos of "PowerSpout" of EcoInnovation (http://www.youtube.com/watch?v=KLzHr0Qntgo).
At yourgreendream (http://www.yourgreendream.com/diy_fp_rewire2.php) there is even a setup available for start/delta connection!
Hoi Happy2Think,
This is my last message to you. After this one, don't be afraid of bothering you again.

Good luck!
Gerard
Combination of Star and Delta: http://www.yourgreendream.com/diy_fp_rewire2.php

We used to have a compressor. Started up in Star, once running switched to Delta.

I think it is a nice device on the same line of the axial flux generator, just this is human powered targeted machine. Nice thread.

Tahnk you

Hi Guzzi_Gerard, I am sorry I had not answered you comments but I have been away from my computer. Thanks for the Threads I think I will have some time over the holidays to look at them. I just taked a peek and it seems to be very interesting material

God bless u
Another nice one. I'm Curious what you think about the Fisher & Paykel 'generator'.
Ehh.... This is the thread: http://www.youtube.com/watch?v=mghM1gpQUyE
Hello,
Below, at the end, some threads to PowerSpout, a very interesting and serious video made by professional electricians about a type of washing machine motor very suitable for using as a generator.
Maybe you don't want to buy a 'ready to fit' generator but build one on your own. Then you don't need to read further. I don't know so I thought I send you this information.

It is the direct drive motor on the spine of the washing machine (no use of a belt). Just came across it on a Dutch site for DIY wind turbines.

Smartdrives, are made by 'Fisher and Paykel', and are used in: 'Fisher and Paykel', 'Whirlpool', 'Maytag' en 'LG'. It's a pity that they we're allready sold 20 years ago in Asia, but only since about 2007 in the rest of the world. Maybe they can be purchased at 'Fisher and Paykel'. See the threads at the end.

A Dutch expert for small windturbines, (I'm from Holland (Amsterdam)) building them all around the world talks about using a asynchrone motor. You need to change the rotor to permanent magnets.

Did you know that the hub of a electric driven (aided) bicycle is also very suitable. Such as this one: http://www.goldenmotor.com/

If you look at the Blog of Hugh Piggot you can find a very nice scheme and simulation. I can not put a thread here because it is on his Blog.
Happy2Think (author)  guzzi_gerard1 year ago
Thanks guzzi_gerard, for these threads I will look into them.
also if you need a nice practical explanation on how to build one of the axial flux generators look into the channel of muddymuddymuddman in youtube he takes you by the hand and shows step by step how to build it.
Here is the kink of the introduction to build an dual axial flux wind turbine

hope you enjoy it

God Bless you
Some other threads. Like you I found it difficult to find good explanations and schemes. But all of a sudden I ran into some very good ones which had links to eachother. I pose them here because I hope you find them useful.
Good luck!
Happy2Think (author)  guzzi_gerard1 year ago
Thanks to you again, I already look up the threads you gave to me and found them very useful. Thanks again

And God Bless You

Indeed excellent scheme. I add two thread for you with explainations about star, Delta, and the combination of them for taking advantage of low revs AND high revs. The first thread I just found! Gives easy to understand schemes. The second is Hugh Piggot's workshop for building your windturbine. He talks about combining star and delta.

Thanks, I will look on the links you pointed to me and if I can, there will be an schema for the DELTA WIRING.

God Bless you
excellent a complete answer to my querey on how to wire the coils. your instructable aso explained the differences of how to use the delta and star configuratios.
Happy2Think (author)  radicalmart1 year ago
I can only say thanks, and when I figure how to wire it in Delta I will make the Diagrams
