One magnet no bearing Bedini motor

[jonnydavro]

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

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

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.

p.s glad your not leaving us just yet Jesus.I for one would miss you and your great idea's.Regards jonny
