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.

Good job Brother, i did similar experiment while i was 15 years with DC Motor from Audio Cassete Player , placed the motor on my bycicle to rotate the motor, and place paralel LED on the tire , it was awsome to see the tire with LED light. keep up the good work. i subs your channel

you can replace the normal magnets with neodymium magnets which is very strong secondly try using ac stabilizer it produce steady ac voltage super capacitor has a silly big capacitance thicker copper wires worse the time and effort LAST ,NEW NOT COMMON IDEA, use a small engine to run the generator and make the generator feed back the engin so it self run Please Keep Me up with your progress For contact Omarhakem0111@gmail.com Whatsapp/Telegram:+201117402627

Would you rewind it or gear it to turn faster? A car alternator needs to turn quite quickly. I'm not sure if it was geared that the wind would turn it. Also would you use DC after its rectified or remove the rectifier and use the AC?

The answer is...Davinci's perpetual wheel. You dont need a wind turbine. Check it out and you may find it to be a easily solvable solution without factering in the need for wind at all. Also look into an ancient Persian wind grain mill. Easily made from an modified oil drum. But it will be a hummer so you'll need to upgrade youre power intake systems. Love Q-PID

I enjoyed your video. You did an awesome job for a non-electronics person. I have been electronics engineer for 50 years and you had me beat on this one. One thought though, you might not know that an induction motor when connected to an ac source and then spun higher rpm than its normal rating will reverse current into the ac source. In other words, if the ac motor is 150vac at 1800 rpm, connected to 150vac source and then spin the motor at 1850 will produce current back into the source of almost the same current as the motor load itself without being spun externally. The motor becomes an inductive alternator instead of being and inductive load. works on smaller voltages and slower rpm motors. Needs to be ac source to get excitation and ac source becomes the load. I've done it - called co-generation. and the reverse current can be measures with a current meter. Just don't overload the motor - it will burn up!! David

try this with a smaller voltage motor with a smaller rpm design. 24vac at 1A at 150rpm motor will produce 1A back into the source at about 200 rpm. Fun to make a wind turbine for smaller voltages this way.
I have a 1000watt ebike hub motor I only paid $100.00 for. It should produce enough hydro or wind electricity to operate a cabin - skoolie - or rv with solar. For sure.

Wow so much fan fair for something you not only didn’t modify Correctly. You gave up. And told everyone it’s a bad idea. Its ok. Everyone has their opinions. But I’ve been on this Progect for almost 3 years. If you want a (real) challenge, build it to kick out 500V. A/C. off the top, that gives you a nice playground to rectify down while maintaining the maximum current. Then build a third party variable output power supply to run the prime mover. Self running baby!!!.... but not so fast! Everything is against you, and it defies the 2nd law of thermodynamics. But wait, what if????? That’s it! Yes!....BUT ITS A SECRET. ...sorry.

a rectifier/regulator for atvs or automobiles will better control volts to close to 12v ( ROUGHLY 14.4 max . if you used it ahead of the dc to dc converter it may not overheat .. ( the rectifier/regulator needs to have its case grounded ) You could also consider using a larger better heat-sink on the dc to dc converter ( and better thermal compound )

To improve the electronics determine the maximum expected RPM which results in open circuit voltage Voc then to determine impedance find the short circuit current Isc. The optimum power ought to have a constant impedance or V/I that is 1/2 to 2/3 of Voc . Meanwhile as RPM increases with wind power, V*I=P increases by the square of RPM. The blades also have a wind impedance achieve maximum power transfer from blade tip velocity to wind speed ratio which needs to be understood. Dutch wind mills have higher surface area than cooter blades so they have more torque but lower tip to wind speed ratio. To maximize power transfer from AC to DC then DC to DC, the load may need to be removed with a passive or FET relay switch so the turbine can get above stall wind speed. Then the idea for MPPT regulation is to match the load to source impedance of the generator. Since Buck regulators work over a smaller input range, a different Buck regulator with higher voltage rating is needed. To reduce the load current at same power, you need to configure the LEDs in series such as 12V strip LEDs. If the RPM is too low to get 12V then we choose a Buck-Boost Regulator but limit the power the match the source power such that the input voltage does not drop below 1/2 Voc . This is define the the KRPM per Volt output and the generator ripple frequency, so both can be derived by another method to predict what the maximum load current can be. Old school might be a Tach cct using Hall sensors or even AC voltage converted to logic levels then to Tach cct with V vs RPM which can be used to regulate maximum current so as not to stall the generator with excess load. You may be able to get 5 to 50W with a wide range in wind power. All for now and remember to try to match voltage to source rather than use 54V reduced to 24 at a 50% loss then Buck to 3V at 20% loss more or less. That works at low speeds but poor efficiency at high speed.

If it takes an electrical charge to spin the motor, then the same motor must produce a current output when the shaft is spun (blades are turning) irrespective of needing magnets. If no charge is produced when blades are spun, then surely the wiring is not setup correctly. Your addition of magnets only seems to add drag and resistance the motor. Better to have charge going into your battery with the slightest breath of wind than to have charge only on days of high wind.

Again, no magnets. In a car this is fixed by using a small current from the battery to power electromagnets to generate electricity. But, you have to have some voltage to power the electromagnets in the first place. So you can't start with dead batteries.

Hope any of this information leads to a open source energy revolution generations over due by my well investagated determenation. P.S. On the level, I would not hesitate to reverse design . Start thinking forever/ colton magnets. This is a perpetual motion generator that once engaged has produce for me at mock up a. +.70 per revolution.

An amplifier circuit could be used to charge batteries, with a check to not over charge them. Good amplifiers will cause very little load to the generator while also putting out more voltage than the source.

I really love discovering other people who think as I do. Now to solve the heat issue in my lesser version. Heat is not coming from the coils or magnets. But from the diode bridge/mosfets. I planned on charging a 12V DC battery bank. But quickly discovered an issue keeping the mosfets set at a certain output. And the old school LM317 and 317T can not handle more than a 2 amp peak output even with a fan aiding their cooling. That is when I opted to try a 24 volt output from the coils. But I still have to charge the bank well before it drops to 80% of full charge, otherwise the mosfets fail. By the way, I am not yet using wind to turn the motor. Using another motor just so I can have a steady output for now. Soon as I perfect the DC conversion, I can move on. lol

Add a shunt vr off an old motorcycle from the 70s. Use the arduino to switch the over voltage to the shunt with a mosfet . But best would be a good set up of secondary capacitors in the shunt to capture the voltage/current then a switched output to drain caps into a battery.

Since wind is an unpredictable and unsteady force from which to acquire FREE ENERGY, I would suggest only using a wind turbine to charge batteries... or large stockpiles of connected batteries... and use the battery system as energy. Kind of in the same way solar panels acquire FREE ENERGY from the sun and then store that energy in battery systems. Is it possible to make it so that the amount of energy coming in from the wind turbine, i.e., higher amps or voltage or whatever, is irrelevant if the energy were being fed directly into charging the batteries. And then once the batteries were fully charged have a system in place that shuts down the wind turbine once the batteries are fully charged?

Very interesting video, but sounds too technical for most, including me. You say in the first half of the videos that the generator will be putting out AC power, which I am confused about. I always thought that these types of devices always produced DC current, and a person needed an inverter to turn the power into something usable.? In the second half of the video, you state that you use a DC to DC gadget, so were you wrong about it being AC in the first half? If so, maybe you should make a correction in your notes below the video? About all the confusing tech items. I had a shake and bake flashlight and all it had was copper wiring on the outside and a magnet on the inside, and you shake the flashlight to make electricity, which was stored in a tiny battery. Electricity is created when the magnetic field is agitated next to the copper wires. So why would you need to remove the inner coils at all? I would assume that they would only serve to create MORE of the same thing we want, which is power.?? Maybe I'm wrong, but I wouldn't think that the direction it turned in, or the direction of the wiring, would make much difference as long as the agitation is happening.? I have a motor like yours and I've torn it down. I'm going to put some used magnets in the case that spins on the outside, and going to run the wires to a battery and see what happens. I can hook the battery to an inverter I have. Ordered a charge controller so as not to overcharge the battery. I'm praying that God watches over me and keeps me safe.

That is a really great idea, because the ceiling fan is a low rpm high torque direct drive motor, just what you need for a wind turbine. However, the process seems needlessly complicated. An induction motor can work as a generator, so there is actually no need for the magnets (but it may need a start-up circuit). The inner winding as the second winding of a 2 phase motor, and it could feed into a second rectifier (it is originally used to start the motor in the right direction). And the motor is designed for 120V. Now induction motors work over a wide range of voltage, but it would be logical to aim for a generator voltage in the same range. That would be more efficient than getting 5V out of it.

Ok the MOTOR will work via ac but if you add permanent magnets it becomes a direct current device . You would get a pulse pattern but it would be DC - How are you getting alternate current? Have you arranged the permanent magnets in an alternating config ?

Not to be critical, but look at the specifications of the motor before deciding to use it as a generator. The motor is unlikely to put out more power than it would normally consume. This is because the windings would overheat under a high current situation (stalled motor for example) and burn up. Outputting the same amount of current while generating will do the same thing. So how much current do these motors draw? It's not much, and I admittedly picked the first cheap fan that I found: www.lowes.com/pd/Harbor-Breeze-Armitage-52-in-Brushed-Nickel-LED-Indoor-Flush-Mount-Ceiling-Fan-with-Light-Kit-5-Blade/1000377285 56 Watts, so a little less than a dollar a Watt. Searching car-parts.com, I can get a used Honda Civic alternator for $50, $25 if I don't mind driving a bit further to get it. It puts out 110 Amps. For argument's sake, we will limit the voltage to 12 Volts. That's 1320 Watts, or 26 Watts per dollar. I've got no idea as to how reliable a Honda alternator is, or if this is the best deal. I just picked one that would seem plentiful, as well as one that I wouldn't need when all of you RUvidrs snap them up. Other advantages of the alternator is that it is designed to be run horizontally, already has the pulley that will come in handy, the bearings are sized to take the load of the pulley, and they are made for a high temperature and wet environment. And arguably you can get as many free alternators as you could free fans (and if you don't care about a blown regulator you could probably clean up on them). And if you pull the regulator out, there is nothing that limits you to just 12 Volts. ruvid.net/video/video-QHRpA_xeFjM.html But your project looks like a fun one nonetheless. Keep hacking! :)

OK , a few things for the rotor in this case your variation with permanent magnets, because the flux will vary very little in operation a solid iron ring can be used to mount the magnets.The hole in the center of the stator matters not the flux primarily takes the shortest path.Air gaps,not ideal but not as big a problem as you might imagine in fact they can be an advantage in some cases.Thickness of the wire only has an indirect affect on resistance or the effect of resistance(voltage drop)the main purpose to increase the diameter therefore decrease the number of turns of the wire would be to create a low voltage device say a12Vor 24V to make a good battery charger dynamo.As far as the electronic are concerned with motors the main problem is inductance or inductive reactance which can spike voltages to destroy electronics and insulation the solution for that is very robust circuits designed for that environment generally if you have enough resistors and capacitors and diodes in strategic places the problem is mitigated.Having a dummy load permanently connected also helps,Have fun.
