Faroun Savonius Wind Turbine

Step 14 PM DC motor generator mount

in this step i was looking to show the diffrent ways to harnees the winds energy using pm dc motor,

i simplified 2 ways as you will see in the photos and the movie.

one way is to use a V belt with 5 to 1 pullies.

the other way is to get timming belt and a wooden disk 3/4" and place portion of the belt arround the cirunfrence glued on, place it on the turbine and the smaller pully that you can get at the junk yad too mount it to the dc motor, you will see in the pics and movie what i meam.

i liked the timming belt better it was less drag and qiuter.

they both produced about 12.25 volts at 80 rmp witch is i am assuming 10mph wind. i know i know soon i will be taking the beast outside, finally sring is here and the snow is gone i hope for few month...lol..

I have a few suggestions:
Not to be rude, but your knowledge on the subject of electromagnetism is a bit thin to be building a generator. All your logic is sound, but a deeper understanding will take you very far. It is mostly mind-numbing stuff but a long grind through it all is worth your time.

You may also want to use Word or some other program to double check your typing. Sometimes in a complex explanation, a single wrong word can really change the entire idea of the sentence. And being someone who is annoying enough to correct people often - I recognized many spelling errors. You will be appreciated greater if you convey your ideas in a more professional manner.

Design wise, a Savonius turbine, like other vertical axis wind turbines (VAWT) are designed for simplicity, reliability, and not having to change to face the wind. By adding wind "funnels" you do increase efficiency in several directions, but you also end up greatly decreasing efficiency in other directions.

Also, one thing to remember with belt drive systems. They rely on FRICTION to operate. And as I am sure you are aware, friction is the greatest enemy to efficiency. Well lubricated gear systems or a chain and sprocket system end up more efficient and more reliable, making up for the added difficulty in construction.

One last thing to this now lengthy comment. I have always designed things with a thought left in my mind by an old high school teacher: KISS (Keep-It-Simple-Stupid). Oddly enough, the SIMPLER the design ends up, the better they seem to work. If it is not necessary to the end goal, remove it.

I may be only 16 but hopefully I will soon be the possessor of several patents for various things I have designed. I wish you the best of luck and happy building.

Great comment and highly welcomed.
you are correct, I do have a problem spelling and not explain my design correctly.
since this design a I have moved on and have invented few different vawts and hawts.
also, I have built 12 serpentine axial flux, not traditional coils.
please check me out at youtube my name is emagnets.

There was one design that used a older tape drive motor it was dc as well like your tread mill motor and you could mount it directly to the shaft. once you have it then you have an on board source to feed the alternator you started with more then one something will gell. likely develop wings and fly.

this might be stupid but i do not know much about gearing other then on a bike wouldn't be better if the gear on the turnbine was smaller then the motor gear that way the turnbine would spin say once and the motor may spine 2 times just a idea

[TheRealTRA]

You have it backwards, the gear on the turbine should be bigger and the one on the motor should be smaller to have, say, the turbine spin once and the motor spin twice.

[Blackice504]

yes thats what i was not sure about as i said i dont know anything about gears the closest thing i worked with was those on my bike even they confuse me some what at times but i was honest so i asked the question because i want to better my self. my field is electronics and computers.

[faroun]

yep, you are correct. thanks

[bongodrummer]

Very nice work! You have got me keen to know how much better your home brew alternator is than the PM motor? Is there much in it?? Nice 'able, thanks!

[faroun]

i managed to create a high producing alternator, but the turbine did not have enough power to keep up with it. that is whay i went to the dc motor. i spent more money building the alternator than the dc motor. regards

[AlternativeUses]

create? will you put up the plans.

[faroun]

maybe the word "Create" is to strong as an expression...lol. anyway, step 13 shows that at very low rpm I was able to produce high voltage. I do not have the best skills to write down a plan, all I have is step 13 to go from. best regards

[Mr Fahrenheit]

Can you add a follow up page or comment on how performance has been?

[faroun]

you are correct, I should do that, but I got busy with the V10 and V8 that I kinda neglected this Savonius, I will get back to it soon. regards
