I bought 2 packs of the 3 spools and just used the thickest I am gona rewind the thicker wire with the smaller wire bifilar, def could be the problem also i am kinda using stolen parts from things.. I have a really neat old relay from bell labs i got at a garage sale....
exact parts would be nice but cash is short, so I'll mess with it tonight and post some pics..
thanks for the help yall, I really appreciate the info.

peace

@Nievesoliveras.Hi.Jesus.I have already tried what you suggest and it works great.The thing is the rpm's are not as high as with the bearingless rotor due to the increased friction of the bearings and the ability off the bearingless rotor to choose where it wants to rotate increases its efficiency so for now that is what i am playing with but the fixed one magnet Bedini is a motor that wants further study for sure and is on my evaluation list.Thankyou for your suggestions,they are much appreciated.
On a sidenote on a  subject close to your heart,here is a vid from Mopozco where he is trying feedback to source with the one magnet no bearing Bedini motor which you may find off interest.Regards jonny

@pirate Hi Bill.That cap could be the key to running all kinds of things.If you need any help,let me know but you want to try to get your motor running on 1.5v and 10mA or less to give yourself a chance.You may have to change your lid to get this low as i found  like Lidmotor that it likes to run at the edge off the coil and you can position it easily with the plastic coffee lid.Keep up your great work with the earth battery Bill regards jonny

I am ashamed now and I want to apologize for my second failure. It seems that the whole thing was a lose connection. I will post no more.
I will not resist a third failure.

I can't see the first ten pages when im logged in, but I can see it as a guest.
am I blocked from seeing that?
anyways
heres pics
only one battery no relay will add that later
trying to just build the bedini then Ill do the spinny thing
but all it will do is make some sqealing feedback....might have burned it up playing around? ???

Hi Pyrodini.I think there are a few things to try first and if no luck follow pirate's instructions for the coil as it is a proven design and vital part off a Bedini motor and if you already have the wire it should not take to long to rewind.That said from your pics and what you say,i would say your circuit is working ok but it is in self oscillation mode. i noticed three pots?For this type of Bedini with a multimagnet rotor you want a 100ohm resistor and a 1kpot.For the one magnet Bedini you want 100ohm+1kpot+10kpot+relay coil.You can just turn the 10k pot down to zero if it is included in your build but the fact that your coil is squeeling means you have to back off on the resistance.
I could not see a core in your coil,is there one?if not and you don't have any welding rods handy,for a quick core just wedge an old 1.5v battery in there,they seem to work very well.
Also i think you may have to many magnets on your rotor.Sometimes more is not better.I found on a rotor that size that it worked with 3,better with 4 and not very well with 5 or more so i use four magnets on cd sized rotors and they fly.
Also does your neon light and just use any old 9v battery as your charge battery.So to sum up i would
1 turn all pots to zero apart from one-the 1k.use your multimeter to check.
2 put a core in if not already there
3 add a 9v charge battery
4 make another rotor with just 4 magnets, don't destroy the one you have so you can compare the two when you get it going
5 Try the snake egg rotor
6 rewind coil if no joy as pirate mentioned in a previous post.Pirate can help with that.
Hope this helps regards jonny

@jonnydavro

Why dont you use the invention as a normal motor like this:

Jesus
Is there a benefit to getting the magnet actually inside the volume of the coil?

Thanks Jonny! Will do, I'll be messing with it some more today and will let ya know when I get it working.
I already wound the coil last night and the reason for the pots is that when I was messing with it the transitor was getting pretty warm and I didn't want to "let the smoke out of the wires" so I cranked the resistance and I just left them in there, I can just turn them all the way down like ya said...

I have a core but I might try a battery, the one I got is a irregular shaped old piece of core from a flyback out of a computer monitor.
also the neon doesn't light up and I will try the rotor with 4 mags instead of so many as well as adding a rechargeable 9v batt.
Thanks again for all your help!

Peace

I am here again. I will not quit. I gatthered my thoughts again. I am ready to work!

I made a test long ago with a coil and a small magnet, I put the magnet inside the air core coil of a self oscillating circuit I found on the energetic forum.
The LEDs I was using and a small 3v dc motor were running real good and the magnet was making a steady rattle inside the coil.
But it did not lasted too long, the coil began to get hot and stop working and still I have not unwinded it to see what happened.

The answer is yes, there is a benefit on getting a magnet actually inside the volume of the coil.

What we need to know is how to wind it so it does not get too hot and stop working and broken.

Hi Jesus and Paul.I think it would be a good experiment to spin a neo sphere inside an aircore trifilar coil with the third winding as a generator coil .The generator coil may be in the perfect position.It would be interesting to see what voltages are generated by a motor like alfacentauro's 150000 rpm job with a third winding.

Thank you @jonnydavro !

That would be a great idea. That is the point, we need to get useful energy or useful rotation from the inversion on this kind of circuits.
For example if the power goes down. It would be marvelous to just turn on one of those no bearing motors and have enough light to at least have a fan, a light bulb and a tv set working.
Because of the high speeds of this motors it would be almost easy to charge two 12 volts batteries and add an inverter to get the ac voltage needed to do the job.

Good idea!

Jesus

Here is a video of me running a One Magnet No Bearing Bedini Motor from my earth battery and a 650 Farad 2.7 volt supercap:

Hello all, I still can't get mine to work  ??? but i did get the motor spinning with a magnetic switch from a doorbell held close to the rotor, but that's cheating, at least my coil is good...
also I am having difficulty understanding the bedini circuit, it seems to me that the magnets when they pass over the coils make very little voltage just enough in the secondary to turn on the transistor .
the main voltage generated on the secondary winding is caused by the initial charge from the first and once inductance kicks in the secondary no longer has a pos voltage and turns off the coil
Does the breakdown of the field causes a spike in the secondary to turn on the cycle again or would that be an opposite charge to go to charging the other battery then the mags turn on the cycle again?

My setup will not spin the rotors or the snake eggs and even with no resistance to the base it will only squeal in what i think is a feed back loop....but that's the point right...is there a way to lower the frequency of the feedback loop? a larger inductive coil maybe instead of the relay coil? I also have the wrong diodes in there and I'm powering it using a 6 volt batt. so maybe i can replace those and it will work..
Thanks for the help!
I'll keep trying until I get it or it explodes and I loose my hands...

Peace

Pyrodin:

Forgive me for asking this but, I saw on a Bedini page where a guy could not get his motor to work no matter what he did.  Then, some other guy asked him "You do realize this motor is not self-starting?"  The fellow did not.  He was thinking that the rotor would begin to spin up when powered and did not know you have to give it a good spin to start the circuit.  I am sure you knew this already, but just in case you did not, it might save you some time.

 ;D while we are on silly questions the poles of the mag are all the same direction right? I have tried a lot of stuff including spinning the thing by hand to see if i could light a led or something...no go....

I think I'm gonna hook this up to an old oscilloscope I have and maybe I can see whats going on a little better

maybe I should use different magnets the neomags are really strong or maybe take out the core
