Turn a ceiling fan into a wind turbine generator?!

A ceiling fan looks similar to a wind turbine, so one may wonder if it can be used as such. Most ceiling fans are induction motors, that don’t generate electricity when being turned. You will have to add magnets. That and many other points are dealt with in this experiment. The goal of this video is to learn how stuff works, and to help everybody who wants to try this conversion themselves. I hope you can learn from my experiment, and make a better version.

Great investigation!

Reshaping the original blades with Papier-maché vould be a fun project to watch.

Ceiling fans is a rich source of entertainment.

Alpha Omega says:

There is no such thing as free energy. It takes something to make something. The power of I/O.

Hans Baumeister says:

One thing I don’t understand: if shorting the inner coils would have acted as a brake, then shouldn’t the reverse be true? I.e.: that some energy would be available from this set of coils as well? Why not leave them in and use the additional energy source? I doubt – with a decent wind – that this would slow the rotation any.

Stephen Perrault says:

If that is your first attempt with electronics then you found your thing man. Start playing with Arduino ‘s. You will fall down the electronic rabbit hole…Nice work.

jim crow says:

Well if you can’t do it, you’ll have to carry on paying yer bills. I watched a Nuclear energy expert , said every house could be built with a mini reactor in the basement, no more, bills… but they didn’t like that idea.

proven22x says:

can it be reversed with magnets on the inside spinning and copper on the outside in a fixed position

JW B says:

Cool video. Since we (Dutch people) have to get off natural gas in the near feature, I am heating my home on electricity (IR panels and convector heaters and I don’t want a noisy and inefficient (below 5 Celcius) heat pump), which cost me a lot of electricity money.
I was wondering if you believe in this: https://www.youtube.com/watch?v=OzOhM4HsIeg . If that really works its gonna save us a lot of money and a bright future, but I don’t trust it. Do you trust it? It looks like a motor is spinning a generator faster than itself via some belts and a flyweel and therefore can loop to power the motor and itself.

Corey Polite says:

does it have to be a working fan or will any do?

Steve Davis says:

I could not sleep well, woke at 2:10 a.m. found this video , and now am 4 times tired. Go figure.

iwilltubeyouall says:

Hey, let’s take a ceiling fan, then remove everything from it and add a lot of new things and make a generator out of it.

david baney says:

you could utilize a set of flyweights which can be found on the old mechanical style constant speed propeller.The idea ,is that at the base of the propeller,a pair of centripetal activating weights extend under centripetal pressure and alter the pitch of the blade ,which in this case would feather the prop.producing less rotational pressure.

Matthew Rode says:

Thank you so much I’ve only subscribed to a couple YouTube channels. Your by far my favorite.

Dennis Milton says:

Where did the ceiling fan go? Blame the failure on the ceiling fan.

chad smith says:

From my understanding of “junkyard engineering” we must first ask “what is efficiency?”.
The ceiling fan build is wonderful because it is a great way to reuse scrap parts. The input (or lack thereof) of money is our first solution of efficiency.
Little input with great output (even if it is not the most efficient generator, it is an efficient project)!
Second, thank you for posting this build for future tinkerers to learn.
But you mentioned that you will be reading the comments.
Well, here is my input on this:
This build is not complete without a car battery (or a bank of them) attached in line to act as a deep stabilizer (depth sink) for the obvious erratic production of electricity. This will take in the produced electricity and allow for storage and consumption later on.
While the regulator is necessary I’m pretty sure that if you use a car battery, the capacitor is useless and may cook the system using both a battery and a capacitor.

Please private message me through YouTube and I’ll send you my email

Xeno Bardock says:

Use magnets in north south configuration with copper coils between, forming a outer magnets ring and inner magnets ring with copper coils ring between. This configuration will cause magnetic lines to go straight through copper coils. Both inner and outer ring of magnets must spin in sync. Make sure no magnet is repelling each other. I think this would increase the efficiency of the electric generator. Also remove all iron as it creates resistance, replace iron with something non-magnetic like stainless steel. Theory.

Austin Shelato says:

what is with the chicken sound effects


Nerd spoof. He has tools, brains and dry sense of humor.

NeverforgetElvis says:

Time to put some “winks” on it. Love this guy.
I too have spent an enormous amount of brain cells trying to think of ways to convert wind energy to usable home power. But like millions before me, we all end up at the bridge of “you can, but at what up-front costs are you willing to invest?” After all the parts and rigging, mechanical and electrical components, hardware, tower, storage batteries, etc…its quite an investment. Also, as this gentleman pointed out, there is much power loss in the system itself: like the power from the output shaft of an engine through the transmission and drivetrain, the net power at the wheels is much less. So the excitement dwindles from the start to the final realization of low net power. And by the time you work out the actual size of a usable unit, you will discover the power companies have lobbied to limit size and height of wind generators in your community. Damn it.

Airon Noles says:

Some heavy equipment uses 24 volt alternators ; especially military vehicles like the M35 Deuce which can be bought surplus .

Nguyen Tanthien says:

Wer hassen wem……………….?

Stephen Ball says:

If you arraigned the magnets around the outside into a halbach array, I would think that would improve performance.

Tommy B. says:

Great work. It is inspiring for a goal towards free electricity for everyone!

E Morine says:

Capacitor should be at least 100 vdc remember capacitors charge up to PEAK VALUE. 1.414 X RMS [what your meter measures]

William Watkins says:

He’ll with all that buy a generator

Robert Stever says:

Wan’t a multi KW voltage regulator? I can make them for this application.

HURAKA Game says:

…but you now know what doesn’t work. #experimentation

Chris Eversole says:

I really enjoyed watching this! I hope you are able to improve it to the standards that you desire!

Hoosier Newman says:

When you placed the magnets outside tha stator were they in NSNS faced? Or were they random?
My suggestions:

Neodymium magnets are far superior than the iron ferrite magnets you used.

Also watch your air gap on magnets (magnet to stator)
Probably 51v max to 24v.

Aeternus Doleo says:

Creative. However, wouldn’t it be simpler to use a device that is already capable of generating a current from motion? A car’s starter motor/generator comes to mind…
Also, next to wind power, a simple water wheel attached to a genny could also deliver a little power. Any small stream, especially in a hilly area, could be partly diverted to power it.

Marshall Pescion says:

I love the setup. Like you said u have alot of voltage when powered up and as u can see the current (heat) builds up too much. All u need to make this machine more broader effective is a higher rectifier and a high wattage power inverter. Your pwm is pritty good but you never said how much amps your pulse width mudulator (pwm) is. No matter. U still can power up quiet a bit for a low amp pwm. Thats all u need todo but it will be alot more costly to make this count. I wouldnt set up your wind generator as is. Do to the various kinds of winds that will come an go leaving you unable to control the really windy days. Good job. I wish my ceiling fan adapters are that easy to take off but i found mine on the side of the road and ill eventually muscle those pieces off. If your not sure heres an easy way to see what you need is by looking on an order site and that has the complete kit and as long as you know what all the parts are for from the kit it will help out what your missing.

HCShuffle says:

I like your project but i dont get why u want to power a device or appliance directly from it. Why not charge a battery and use that? After 7 minutes it seems to me you are creating problems.

Del Schier says:

Why not just use an auto alternator, they work without modifications and can be found used if not free also.

proven22x says:

can the magnets be placed above and below the coils or must they only be placed on the outside

Garbled User says:

If those inner windings were kept but reordered, they could be used as a saturable reactor. You could use DC to increase the saturation of the core, and therefore increase the AC output voltage.

Kevin Chamberlain says:

Well beyond my capabilities but a good project!

kerutc says:

🙂 Maybe it would be easier to build one entirely from scratch 🙂 Seriously, impressive!

LANPartyAnimal says:

This was fun and informative, thanks. The only issue I saw was the lack of any tilt in the rotor blades you used. If you want the wind to turn it there has to be an angled face to the direction you want the wind to push. I’m replacing a fan so you gave me an idea to tinker with the old one. My wife will not be thanking you for giving me a reason to hang on to it.

JOE OGBU says:

Everything about this video is good. Thanks for the lesson.

Antoni Torres says:

Look up jerard morin on you tube.

We are always watching says:

Thank you for your time and effort in making this very educational video. I’m also an engineer, I’m mechanical and electrical. You Did great.

Erik Sliman says:

enjoyed a nice video that helps us newbies understand some of the basics in a practical application. thanks!

Mangosuthu Buthelezi says:

Thanks for the video. Are you Dutch?

Raven is better says:

So you didn’t turn a standard fan into a wind generator.! What a waste of my time and a “MISS LEADING TITLE”…….!

Icky says:

what about a car alternator? it already has everything to take ac current and turn it into steady 12v dc.

Timothy Carey says:

I have Duchenne Muscular Dystrophy and I am 45 years old. I can’t move my arms. I love making electronic projects, but my problem is I don’t usually have people I can help with this kind of hobby. But I have made some things.
