How to Make the Coil for the Bedini Motor (SSG/Schoolgirl)

[haz939]

Would a toilet tube work for a coil?

[camelsonhorizon]

you should emphasize which direction to wind it, and where the wires go onto and off of the new spool, because that makes the N and S. Like- insert on inner part of spool on the left side, wind toward yourself, exit on right side , outer edge of spool

[lhakvoort]

where did you buy the magnet wire ?

[carveymaigue]

I have a question after making the coil, are wires attached to the steel core? how come it becomes an electro magnet if it was not attached? the iron core is separated by the spool's shaft right? how come it becomes an electromagnet? and there are also insulators in the wires how come it becomes an electro magnet thanks

[carlosreina100]

hello that such excuses do not speak English I speak Spanish, but you are disturbed by the construction of the coil, I look at you join the two wires together and put back on track that is all, is that a wire is thinner than the other thanks you help me?

[VotreCauchemar]

Did you used an average [Cu] wire? or is it an special variation?

[pkrska]

What's the difference if one uses a 43 ohm resistor or a 1K ohm resistor? I would like to understand what each parts doing. I created a the school girl design and I could not get enough winding. I ended up with 350 with a 1 inch center. Is this too big. Does it matter more how big the center of the coil is or the amount of windings? Should I make it a smaller center to get more windings? Will it work anyway with the 350 wraps? I am also wondering how far to place the spinning magnets from coil?

[bentboybbz]

so the wire has an insulator on it???

[introvertebrate]

yep... it may not look like it but magnet wire has a thin layer of insulation around it... normally enamel

[Jamieduk999]

@introvertebrate what ga wire you rekon he using as i need some wire but dont know what ga to get?

[samking12]

what is that coating on the wire if it was burnt off can you repair it

[introvertebrate]

you can get different kind of coating but usually it is enamel... it can be burnt off.

You could repair small areas using heat shrink or insulation tape. Glue is another possibility but I doubt its reliable. Depends how bad the damage is...

[jbraun32]

is there a ceertain direction the wires have to go to create the north magnetic field? i'm building a motor based on your diagrams in your other vids. the circuit works, but when i hook it up to the coil, and stick it next to my wheel, it doesn't make the wheel spin.

it just repels it and does nothing else. thanks for the help!

[introvertebrate]

you can reverse the poles by turning the coil upside down... but it sounds like the coil is the right way up but there may be a short in the circuit... were you using a neon?

[jbraun32]

no i wasn't. i'm trying to build just the motor right now and not really the charging version. i took out the battery charging part of the circuit and it looks just like bedini's simple motor diagram thats online. i have the led bulb, a 5k potentiometer, 10 ohm resistor, the same transistor you have in your vids, and i hooked it all of the wires from the coil just how you did it. ( i have 900 turns) this is my first time to ever try to build one of these so it's pretty confusing.

[introvertebrate]

I think your transistor may have fried... the neon bulb is there to protect the transistor... if there is no charging battery or neon attached then the transistor will almost definatly fry :(

[jbraun32]

ok! thanks alot!! :) i'll try that!

[Jimmeh30]

nice one introvertebrate mate :) u r right in that the more uniform the coil is the better it will perform, one suggestion tho, I have found that if you wind on the spool from left to right, laminate with tape and then wind each progressive layer in the same direction (ie: left to right on the spool), the performance of the coils increases again. I have no idea why, is mearly an observation :)

[introvertebrate]

nice observation (thumbs up) Will give it a go on future coils! Cheers!

[jon95772]

is it better to have magnets the same size of

core or larger than the core?

[infamousartgallery1]

so when winding the coil do all the layers have to be perfect???

I am using 23g and 26g wire, the first row of winds comes out great but then after a few passes back and forth the wires want to start imbedding themselves in the previous layers. so my question is do all rows and layers need to be perfect??? any help would be greatly appreciated as the coil construction is holding me up on my finished motor.

thanks

[introvertebrate]

The coil doesn't have to be perfect. ^_^ wrap it as neatly as you can.

A poorly wrapped coil won't perform as well as a well wrapped coil but it doesn't effect the performance as much the other variables like core material.

Perfection is a good goal to go for and I did wrap a near perfect coil once by cellotaping a layer of thin paper between layers. This makes it much easier to wrap the layers in a uniform manner.

[introvertebrate]

But it didn't appear to perform any better or worse than my other coils so I'm not sure if it was worth the effort ^_^ Just take your time but don't worry about it being perfect.

[infamousartgallery1]

thanks for the info.

by the way...... Great work!!

[vietarc]

I'm not into the motor themselves but I do have some belief about bifilar coils. I believe Tesla used them to cancel out the magnetic field generated by the coil. I think cancel out that magnetic field means obsorb that magnetic energy. So basically, you can get max 200% power for the price of 100%input, and it keeps looping.

[Drevtoobe]

"However my self runner was running on 950ma (just under one amp) for 21 hours and it was only half charged to begin with! So in theory it generated almost 6 times more energy than was in the battery :)"

You are so enthusiastic that you are jumping ahead of yourself. Let's look at what you really said above: You had 3.6 amp-hours of energy in the source battery and your motor DISSIPATED 0.95 x 21 = 19.95 amp-hours of energy. You were talking about the load on the source batt, not generation.

[amorbrujo1970]

Dear Drevtoobe, first i wan to apologize for my english. I agree totally with you about consuming and not generating... but the totally disipated energy is more than in the battery.. how is these possible (is a violation of conservacy principle)? I'm not talking about the motor, i'm asking about the battery.. i don't undestud (i think maybe the current is not 950ma constant, maybe is a strange waveform an he is measure the square of the medium power in a wrong way, what do you think?)

[Drevtoobe]

I can't remember what clip the comments come from that is the basis of the discussion.

Most likely the person doing the measurements was using a digital multimeter which is useless for measuring pulse voltage and current waveforms.

[Drevtoobe]

I just looked back and found the quite from the host Introvertebrate.

I can only guess that he was using a digital multimeter and he was making a rough estimate of the amount of energy left in his battery.

[amorbrujo1970]

Yes, i agree. Digital or analog multimeter in AC only meassure the square of medium power and is only usefull if you meassure a senoidal wave [sqrt(2) correction factor]. To any other different wave is useless.. thanks for your replay.

hi every1

I'm almost finished with my first bifilar coil, around 900 winds, not very tight, I still have some wire left for about 50-100 winds, is 900 enough or should I finish all of the wire?

For the core of the coil I want to grind some stainless steel scrubber (those things that u use for very dirty dishes) in my coffee grinder, mix the shavings with some paper glue and pour all of that into the core of the coil, would it work fine?

[introvertebrate]

Hi! Best to add as many turns as you can... I don't think there is an optimal amount of turns... more the merrier!

not sure if stainless steel is such a good idea... it might help if you ground it up but in general steel retains its magnetic charge alot more then iron... you can give it a go but I would reccomend iron filings or magnetite sand....

good luck with it!

[bergweg]

Hi

How many gramms of iron powder would one need for one coil core (length 80mm / diameter 10 mm)? I don't have any iron powder to see how much I really need. I've found sellers on eBay that sell iron powder, the bigger the amount the cheaper it costs, so I want to order more for future use.

[1miltond]

Hi I want to congratulate you for your effort and the quality of your videos Primarily the one about How to make a bendini motor #1 and #2 en Very Very good I would like to ask you a question Ia not an optimist abaout free energy BUT I am about a low cost energy and perhaps one where wee can apply 12 v and get 110 ac My question is about TORQUE HP that can be achived wiht Bendini motor Velocity is inportant But HP is de key Wat do you think can be done wat need tobe done more coils

[introvertebrate]

There is not much torque with the bedini motor... though it is possible to add more coils and get higher torque... I still need to do experiments to see how adding a load to the motor effects the charging efficiency though interestingly when a load is applied amp draw goes down...

[introvertebrate]

there are other "free energy" motors I haven't tested yet that do have high torque... the E V Gray motor is probably one of the best, and there is also Peter Lindermann's attraction motors.

[1miltond]

thank you for you answer let me know if you find anything interestin about the subject from my part Ill do the same. I think it would be a very good to have an audio an video chat were we can use camaras to show aur projects and discuss ideas sharingthis whit people interested in the this subject paltalk and yahoo have private chats rooms that are free thatwillaccommodatethis tipe of things Im pretty sure you know aboutit

[alex681219]

see the rodin coil winding and xperiment with that...HP and naudin reports that this coil winding have a huge increase of the emf called this electromagnetic ventury.

Have a happy new winding!!!

[thedarkener]

Can you explain exactly what this does? =)

[introvertebrate]

the coil is a part of the bedini motor... the thin wire is the "trigger coil" that generates a current when a magnet passes over it. this current flows into the transistor. A transistor is like a switch that turns on when a current flows into part of it. when the transistor turns on it sends current from the primary battery through the thicker wire in the coil and pushes the magnet (that generated the current in the trigger coil) away and keeps the wheel spinning.

[introvertebrate]

hard to explain what the motor actually does in a text comment! there is a brief summary of how it works in my "how to build a bedini motor part 1" vid :)

The circuit basically generates another form of energy that has many names but is commonly known as Radiant Energy. This energy is then channeled into another battery and charges it! Over unity is fun!

[introvertebrate]

to give you an example of it producing free energy:

My self running version (introverted schoolgirl motor) runs on one battery, a 7.2 amp hour battery, which means it has enough energy to generate 1 amp of current for 7.2 hours. However my self runner was running on 950ma (just under one amp) for 21 hours and it was only half charged to begin with! So in theory it generated almost 6 times more energy than was in the battery :)

[Drevtoobe]

"However my self runner was running on 950ma (just under one amp) for 21 hours and it was only half charged to begin with! So in theory it generated almost 6 times more energy than was in the battery :)"

That sounds pretty exciting, doesn't it? I hope that you read the series of postings that I mention elsewhere on your page. I don't want to sound arrogant but I can tell you already that your measurements are wrong. You did not generate six times more energy than was in the battery.

[Careica]

And yesterday I get 20 ferrite magnets :D

[Careica]

Thanck you so mutch! My friend have found lot of coil wire so I have now all to start building my own. I have startet now by circuit.

But Thanck You!

[labidus74]

Is the iron core you are talking about are black sand or its another thing?

[introvertebrate]

black sand i think is an iron ore which is supposed to be very good but iron filings are good too. My prefered core material ^_^

I do like to point out that bedini reccomends welding rods and i'm sure there is a good reason for that.

[sirHOAX]

Think he is talking about Black River Sand or Magnetite. This is now found as Black Dry Toner Ink. This material tends to magnetize extremely rapidly and demagnetize the same. Might be better for pulsing. Just in case anyone wanted to know.

They might mix it with Black Silicate to melt with the Magnetite in an oven to make cores. Or I was thinking possibly mixed with clear epoxy to make custom shapes.

[labidus74]

yeah the rods are supposed to response faster then iron, but black sand is faster. but black sand attrack less then iron (what i heard) :)

[sirHOAX]

Not sure, but the Magnetite has been recommended by others like Peter Lindemann for these type of applications. Might be the fact of getting a quicker more efficient back EMF spike on the coil. Plus the fact it could take less energy to charge the Magnetite rather then a dense material like Iron.

Regards, --S

[sirHOAX]

Also another unique thing about it, it will not hold any type of magnetic charge once the charge on the coil is released. Iron on the other hand will in-fact hold a magnetic charge, even permanently. Which for the Magnetite this is impossible.

Food for Thought, ::sirHOAX::

[introvertebrate]

lol.. not quite impossible to magnetically charge magnetite! You know lodestones? they are magnetite. but i agree... magnetite has a much faster switching time than iron and is less willing to hold onto its magnetism.
