mendax: @OP,

What is the range of RPM for your motor. I know you said you needed a low RPM motor, but what range would you term as low RPM for your project. I'm not familliar with the exact thing you want to achieve but may be able to help sourcing for the motor. Best of luck

Anything with a ratio of RPM/voltage of <15
Eg. 250RPM n 24VDC
If you do the maths it gives you just over 10volts DC.

But this poster hu$tler just mentoined something very interesting, I just hope he will tell me more.

hu$tler:
I ve worked on this project before. I can tell you the best DC motor to use is a geared DC motor. There are some geared motor which can generate up to 24V at 45 rpm and they are relatively cheap.

This is just what I need, where do I get surplus of this motor. Please?

Funkymallam: Mods need to encourage this dude!

All d best Sadiq.

Thanks for your concern, I appreciate a lot.

elume2020: My friends did a project on windmill, with d blades made from pvc pipe, like d ones used in toilet. I will contact them if there is any help they could offer. I will also think through to see what can be done. I graduated frm FUTA, MECH. Eng dept.

Please do, I really would need all the help I can get.
Here's my mail sadikk99@yahoo.com

aguiyi: i wish you success bro

Thanks, that means a lot.

Yeah, it did thanks for that.
But the problem with the epoxy and magnets still a major issue, maybe you have an idea where to get them?

I am planning to keep you guys updated on the progress that I make up till the end and the presentation and exhibition. Gods willing.



[size=13pt]Mods, please please help me! I need as much people to see this, you never know who might help. Front page if its not too much to ask. Please!!

Hey guys, my name is sadiq. I am a final year student studing mech. Engineering. I am working on a wind turbine for my final year project, I just recently started, I have done a few things though not much.
Well, here it goes.
In my short time in taking up this challenge I noticed that the project fundermentally relys on two things every other thing is no problem, this are
1. Wind
2. Motor
Its is meant to produce at least 15volts to charge a 12volt battery, if however I can't reach that mark, then 10volts woldnt be too bad, I could use to light some LED bulbs. Lol

So, I started with the blade construction, I didn't want to start from scratch using wood, so I went with the PVC pipe. I used a 6" diameter pipe with a lenght of 24". I did some rough math induction and came up with the blades(pic below). So that's done with. Moving on to the next.
Generator, I wanted to construct my own generator, but couldn't find some components like neyodymium magnets and eproxy(although considering this again). So I decided to go with a DC motor, the challenge of that is finding a low RPM motor. Tread mills are good sources for such but I have only been able to come accross high RPM motors. So that's a big problem for me and I am running out of time.
I have not been able to do much again, because the whole project depends on this component, the rest in not that major work. Its just the stucture(nacelle),furling,tower, wiring, charge controller, battery.. There's some bit of interesting construction there, but hopfully it wouldn't be too much trouble, God willing.
I have started on the charge contoller, although I am not the one working on it(its more of electrical). Its just a box with some circuits which turns on and off, or rather charge battery when its out of juice and dump the load when its fully charged.(The concept pic is below)
Almost forgot, I wanted to use a pulley system but taught of the losses and decided to leave it out. The wind is not high enough to make up for the losses.
Guys this is a major thing for me, am sure there should be people around who have done it before, or at least have seen where it was done before, so I'll appreciate if you help me out with my motor/generator problem.
Any form of assistance would be highly appreciated.
Thanks.

Guys I need help, working on a wind turbine as my final year project. I have run into some difficulties, mostly the motor to use for the turbine! Any ideas please??

Has anybody actually done it before? I am currently doing it but don't know which motor to use. I know I need electric motor, but a low RPM motor is hard to find, any ideas?

Why is it so difficult to locate how to start a new topic on nairaland?
Can some help me out please. *angry*

Ok!

abdulkayus: keep dreamin, islam will remain and even prosper and u will come and go, better wake up from ur slumber

He/shes actually right in a way, one of the signs of end of time remember!?

Why oh why!! Land of the pure!! I only aask why imitate the west!?
Let them go and do their olympics only them, why compromise for the west?
Oh well, all signs I guess!
Allah yasa mu cika da imani!

In terms of what?
Look at me, who am I kidding. like it even matters! Mechanical all the way!

[size=13pt]Someone who studies engineering at the end of his/her 5 years in school is called an Engineer!
On the other hand what do you call someone who studied comp/science? Anyone??

I have had this question, was wondering if anybody would be kind enough to help we with it?[/size]

[size=22pt]why do nigerians have short memory or is it that there just fund of asking pointless questions??

Shm

U should take a case study for your self, all thos prominent women in nigeria what have they done

Alison
Iwela
Cecelia
Patricia
Yaraduas wife
Gejs wife
Dora
The list keeps goin on and on

From stories we have heared its safe to draw up a conclusion to your case study

This all IMO
