I try to make it selfrunning like show in scheme, with black diode and without it, but it not selfrunnig. I use 16 V 10000 uF capasitor.
If on one stator coil wind other coil and conect to source trought diodes, and from 12 V and then disconct 12 V, it stop seems slower, than without it.

I think to chare battery beter not modifi fan, but wind on each coil, stator pole, other coil and from it trought diodes get + and - and chare with it battery.

hdsat,

Thanks for posting the schematic. It is a work of art.

Hello,

Iam not an electronic and just start electronics as a hobbie.Just finished my first project, a Julie thief with success cause of the help i got by reading the forums
Now iam trying to build this bedini-imhotedp motor and cant find the right diodes(ECG125) locally.
What i found is a IN4007 diode.Is the IN4007 going to work if i use it?
or you can suggest any other diodes to work with ?

Thanks,
Michael

"What i found is a IN4007 diode.Is the IN4007 going to work if i use it?"
It work, I think, but efficienty motor may can be less.

Hi All,
I am new to this forum and really liked its projects.I like Imhotep,s Bedini Fan project and tried many time but no luck even changed fans with bigger size.My components are 2 1n4007 diodes,1 2n3055, 5k gain and 1 100 ohms resistor and one 12v 2Ah battery dead for charging.My fan only turns one but not spinning.I checked my components which seems fine but not working.Any help will be really appreciated.Thanks in advance

Hi jas2010 did you wind the coils one clockwise and the other counter clockwise? If yes do hear a squel from the coils?
Did you try to push the fan to start?
Check these first.

@ Guruji
Thanks for reply
Well actually i havent wind the fan coils but modified as separated coils according to Imhotep,s video.Also try to push fan but nothing happen s .Also i want know that how i drive fan,I mean circuit diagram to drive hard disk motor,floppy drives motors etc.Thanks

UF4004 diode (ultra fast) seems to work pretty well from collector to charge batt. Produces higher Voltage spikes than 1N4007. I have not tried schottkys.

Jas
You only make actually 2 Coils. 1 Coil triggers the Transitor at the right Moment.
The other coil pushes the Rotor magnet.
At the Fan, you bind 2 Pairs to one Coil.
When your Tranistor dont open at the right moment, only switch the Ends from one Coil,
like the one at Minus and Base from Transistor.
You 'drive' the Rotor with the Resistance at the Base, but adjust it to highest Rpm and lowest Amp draw.
Diodes are like Valves, what are closed, with Voltage at one direction they open.
Different Types can handle more or less Current or close/open switch faster.

Thanks for replies I will try these options so see whats happen s

Hey , I am new to this forum , looks very interesting , i found Bedini's imphotep fan circuit on youtube , gotta say it got me interested , i am thinking of building one after my exams are done , but i keep asking myself this question (what's the purpose of this circuit?) , i mean all i wanted at first is free cool air , I am not really interested in charging "dead" batteries , and what happens when the source battery gets fully discharged? , the fan would stop right?

Sorry for sounding ignorant , just a 16 year old hobbyist.

Montaser,

Ignore this thread tittle, it is misleading. Circuit would still consume around the same amount usually needed to turn the fan normally.

No, the fan will continue turning.

Edit:
I misread it, the fan will stop if the source battery depleted. The fan will go faster if the charged battery is fully charge.

Sorry for the confusion.

This is just a prototype to teach you what you can do. You drive mechanical and can also charge the battery.

As charger it is useless because I see comment about getting fully recharged after a week. That is serious power waster.

Sucahyo , thanks for clearing things up mate

@Stargate22 dude go play GH

Basically what you're saying in the video is that you've gone through some extensive work creating that little circuit to just barely power a neon bulb with a battery? All of that work could've been done with just a battery connected directly to it. It seems like you're getting absolutely no benefit from doing all of that work. Trust me, if that stuff really did create free power, it would've already been marketed to people en masse.

At first I was kind of impressed because I thought you had just the fan itself powering the bulb by generating electromagnetic fields via moving a coil of copper wire between permanent magnets. Instead, you've supplied it with a battery, using the rotation of the coils as simply the "on switch". Plus, you have to overcome back EMF when turning any armature, so a larger-scale application is essentially impossible, considering the amount of energy wasted on keeping the armature spinning without simply generating a lot of heat and breaking the components in the generator.

Barely powering a neon bulb is no sign of "free power". A few milliwatts generated is nothing when most appliances in the home are hundreds of watts. I think this is just another miserable failure in the search for alternative energy sources. It may be a neat project for kids in their science fair, but definitely not a step in any direction for alternatives.

Alright Mr kidsasuke Sir Grandmaster

Btw, did you realize, that we do charging normal Batteries with this Circuit?
The Circuit is since a while out, not just since 6 Months.
And did you even realize, that it is possible to charge Batteries?
And not opnly 'Fresh them up a bit' like some Manufactors claim,
'because it is not possible, to charge Batteries'.
So tell us. Mr Grandmaster, where are all this Devices,
what charge the Batteries. Anywhere at the Trashcans like the Batteries,
what are trown each Day around the World into the Junk?

The Imhotep - Bedini fan conversion is a very usefull device, it is a good project to start to learn of these things, I still have the first one I built and it still works and it works good, I am still using batteries that i brought back to life with it. I pulled it out today to take this picture.

http://public.bay.livefilestore.com/...005.gif?psid=1
Here it is in it's glory days, it fixed all the old ups batteries behind it.

http://u7beag.bay.livefilestore.com/...ar1.JPG?psid=1

I am very glad i built it, without Imhotep and John Bedini, I wouldn't be fixing my batteries.

Thank You

The fan is good.
Excellent learning tool.

Farmhand, Can you identify the transistor in the pic?

Yes of course, it is a - C5027F-R , The fan is a Thermaltake .4 amp high speed single coil fan, I split the single winding in two, not easy, quite thick wire in these fans.

The original single winding covers covers the "four" stator bobins.

Cheers

Cool thanks man.

It would be good for a newbie (like I was when I built my first) to have a list of suitable trannies, where they can be scrounged and notes on their advantages or disadvantages.

Peace
PJ

From Wiki,

This is interesting

Imhotep - Wikipedia, the free encyclopedia

Yeah cool, but nothing 'bout the guy who open sourced the fan conversion.

I'm learning so much from all the fine people here who give of their knowledge. Thank you Imhotep for this project and thanks to all the other members who built this and shared their experience. The modification was fun and I cant wait to get a bigger fan. Here are a few images of the modification in action.

Hey, just the fact you can charge one 12 volt battery, with another 12v battery, without a DC step-up transformer...AND the source battery doesn't die a quick premature death AND it keeps the flies off you in the shop.

Come on, what more do you want for nothin.



Even if Bedini and IMHOTEP were out to lunch (which they are not!!! Not in my opinion at all...) EVEN if NOTHING they invented worked...

they both have made us all think about a few things (maybe for the first time in a long time?) and that is...

Open sourcing our knowledge
Re-using stuff that's thrown away (including high voltage)
spatial energy relationships

That's highly commendable in itself.

Not to mention John's kick ass audio equipment, Dear Lord have u heard it? mmmmmmmmm

Hello everyone
I apologize for my ignorance, but I do not know electronics.
I would like to create this circuit.
You can complete this picture?
(eliminates errors, complete the wire path and add all the polarity)
Please
Thanks

Look like the diode connection is wrong. Your transistor drawing is ambigous. Is that bottom or top look?

For potentiometer, connect one in the middle and one in the side. Please add battery drawing too, the source and the charged part.

Hi folks, I never did get around to making one of these fans, but now I have.
I still have to slap together the external circuit and I'll see later today if she fires up. It's a 120mm pc case fan/ 4.375" diameter fan blade and the sticker says 12v @ .3A. Here's a couple pics of the beast. Oh and each set of coils are 50 ohms

After burning out the transistors in the Bedini 5 inch fan kit.I attempted this one. Have only managed to wreck two fans so far. But I have plenty more old computers with fans in them to try. Guess I should attempt another one. Eventually might get it right.

stargate22 thank you very very very much. now look. if I have problems, I tell you.

Hello everyone I am new to the forum but have been looking at the different and presentations for a while now, and find some of them very interesting especially imhoteps. I am a firm beleaver in simplicity and he does a good job at doing that. There has been a question I woud like to pose to the forum. What do you get when you combine a 12v battery, an inverter, an electric motor, and an alternator? Is this not the componemts for self running, overunity device. I seek your wise advise seeing that I am interested in putting together this idea. Thank you in advance for your help. Fluteman

There was a patent granted for this type of device. It is mentioned in Patrick
Kelly's book.
