Hi everyone. I have tried for a long time to make myself a windmill with little sucsess. Most of my projects i have given up as off loss of confidence or the fact that magnets cost ALOT in norway. (Probably 5 times as much as in USA) But i am yet to give up my quest for green power.

So about a week ago a friend gave me a SEIMEC italian motor that came off an industrial machine. And i belive that this could be a great project to start on, as all i miss now is the magnets(in theory) Can you guys verify this for me tho?

The engine is complete, but i have the axel in my car, was gonna get someone to make me one lighter in strong aluminium with room for magnets.

The plate say the following: TIPO HF: 80/A2, CAV. 1, Kw 0.75, GIRI 2780, SERV. C, POLI 2, Hz 50, % 75, COS 087, Fase 1 is 220v, 2.9 A, second fase is 380V, 1.7A. I have no idea what this means, but im sure some of you have some idea. Anything i need to know?

I't weights about 5-6 kilos, 10-12 pounds.

So my big question is:
A: Will this make for a great low to medium rpm windmill?
B: What sort of magnets and how many would you recomend for this build for a decent output to charge a series of car batteries.
C: What size blades should i make for it to operate decently, and shoule i make them from PVC or should i go for fiberglass wing shaped blades.
D: How do i wire it ? :s

Well thats a mouthfull of question for you guys, hope i get some awnsers in here :D

PS: Any videos or websites that explain and show how this is done would be apriciated, as i find nothing in this caliber.

Lots of love from Norway !

Wow, this is very much useful article. Thanks a lot for posting this type of information.

If you look at the end of it, there are some questions too.. To little information would allso be bad. But its not like this forum is really providing any awnsers anyways.

Thomas, sorry there's nobody answering your questions. Unfortunately I have never done a motor conversion myself, and can't help you either. The forum has been pretty quiet lately, and the people that have done this type of work before seem to have moved to other places on the Web.

As to Ringo, he/she is just providing back-links to his own Web site, to increase the Google page-rank, hence his utterly meaningless reply. He has no intention to actually provide any information. I should probably ban people like him, though it's too easy to just sign up again under another name, so out of my own laziness I let this type of thing slip by.

If you do get the conversion done, please feel free to post about here (with pictures!). It would make a great story, and something many others would be interested in.

Thomas, here is a useful link (much as it pains me to point you to "the other" forum):

http://www.fieldlines.com/index.php/topic,143568.0.html

The article it points to is a collection of links of induction motor conversion, just like the one you want to do. The first three are more of a tutorial.

Take a look, hope this helps!

Hello Thomas,
Am I too late?

The motor can be converted into a generator. BUT. It will be very limited unless you are committed to creating a new rotor with many magnets, and re-winding the wire around it, too. Even so, do not expect a miracle!

If you haven't already given up, I can give you some more information. I haven't seen you posting questions on Fieldlines, so you may still be reading up about it!
