One magnet no bearing Bedini motor

The shape is truely important!

I would stay with the snake mags as they are shaped better to facilitate the air coils around the sides. Yes teflon spay would also work. But as you seen in lidmotors example the sides of the lid tend to slow the magnet down alot. Hence why it would be better to use a slight bowl shape in the lid. Then flat area around that for your coils to rest on.
Has anyone figured out why this works like it does? It definetly looks like the magnetic forces are in a vortex above the coil. Does varying the frequency also change the speed? Are these bi-filiar coils?
Great work guys this is very exciting to see that this works the way it does.

It is very hard to find a perfectly suited bowl shaped lid and hot-bending plastic like Pirate has done can work, i made one now, but the right shape is crucial, i guess it is not steep enough on the edges, but too steep will crash the magnet.

I have tried some other lids today, just to find out that with the one i had used before the little hole in the middle, that slowed the magnet down a bit, is necessary for a flawless operation. At 12 V the magnet will speed up that fast and it will always wander to the edges and finally crash into the pickup coils. With a bowl shaped lid it is pretty impossible to start the magnets rotation up, it needs to be manually rotated (with a lot of force) flat before it erects itself and starts rotating the way it does.
It is really really hard to get it going

Due to the fact that i want a 12 Volt system to charge big batteries off the collector, i try hard to get this working with a 12 V source.

A lower voltage source will not accelerate the magnet that much.

A lot of tweaking has still to be done.

Only the primary circuit coil is bifilar, the aircore coils are monofilar.

@Lidmotor.Great vid Lid. My you work fast.Thats probably a good way for anyone who has already got a bedini to try this,just up end the coil and away you go.
If the circuit you are using is the standard Bedini with the 100ohm and the 1k pot,you won't be getting the full rpms and lower current consumption.My motors trigger resistance is 6680 ohms when it is going full blast.This is the 100+1000+5540(10kpot)+40 for sephiroths 12v relay.Just adding the 10k pot makes a lot off difference but adding the relay should drop the current consumption plus give you 2 bemf outputs which i have had joule thief on so god knows what you could do with them.
Thanks for replicating this Lid and i see pirate has just got one going using your coil design so lets see what we can do with this.Regards jonnydavro

Bigger capacitors and new lid

YouTube - Bigger Puffer Capacitors

A little improvement of the charging from the pickup-coils to a 3rd battery

[Jbignes5]

Very nice!

That is a way better, I'd say major improvement! Much smoother and not so much banging the coils. Awesome!

I was thinking earlier, *Thinks, Oh Nooo, not thinking again*, if you redid the air coils so they were like this "0" instead of "O" would you be able to fit more of them around the magnet? Like when you form them you could use a piece of cardboard then slip it out afterwards or even leave it in. Kinda like a cats eye. It might let you get more coils around it. what do you have now 4? I was thinking like 6-9. Is that a good idea or am I way off? It should net you more current I would think.
I love how this is evolving as you go xenomorph. You have a talent for building. I am gona start my first experiments and start doing videos soon. It looks like a lot of fun!
On the cup of the lid I only have this to say about it that it should be very very small depth. Just enough to keep it from going too close to the coils. I understand how hard it must be to start but I think you should go half way with my suggestion and have a flat bottom in the cup with slightly curved edges leading to another flat lip for the coils to go on.

Kinda like this:

Try that if you can and see if that would help with starting it.

[Vortex]

Do the forces that spin the magnet also keep the magnet over the coil?
If a much larger platform was used would the magnet escape from the grip of the coil and run away?
Would the magnet stay above / over the coil without containment of the platform lid/lip/etc.?

Does this spinning only occur using a bifilar coil and thus the magnetic field
created by the second coil is required to spin the magnet?

@Vortex:
This works like a standard Bedini circuit.
The magnets rotation induces current that triggers the transistor, which in turn pushes the magnet. So a monofilar coil would not do anything except you create some kind of oscillation in that maybe, but thats what the magnet is there for in this case anyway.

The movement of the magnet is entirely random and in certain cases it can accelerate itself into a direction and pick up as much kinetic energy into that direction that it will fall off the lid.
It is really mysterious what fluctuations the magnet is going through when you observe it for an hour hehe.
So a proper base resistance setting is crucial to keep the magnet close to the center.

@Lidmotor: Cool that you tried this with a trifilar, i have been wondering what a third winding could do. Nice one!

[Jbignes5]

Wow very kewl.

Hey guys had a dream last night about this and was paying good attention to my dream setup. Could you try this for me in the mean time until I get my setup going.
1: I know startup is hard to do. In my dream I made a paper tube and taped it. I cut it to 3/4 the length of the magnet. It had alittle room around the magnet so that it could spin. I placed the end of the tube on the surface then placed the magnet into the tube and spun it up. Once it was going I gently lifted off the tube and away it went. Try this and see if the startup gets easier that way.
2: Both a question and experiment. Does position of the magnet have anything to do with how it runs? Ie. Could you put a wire cirlcle, just a magnet wire of about 20 awg in a small ring of about the size of your thumb with both ends soldered together, then place it on the surface and held there by tape or hot glue. Would that work?
3: If 2 works could you try putting the wire circle in front of one of the coils and try another circle in front of one of the other coils with a second magnet. I know it might be hard to do but if the paper tube works for the startup you could place the tube end in the circle wire guide and slip the magnet in and start it that way, again if that works. That would be interesting to see if the magnets would run that way. I'm going on the great snake egg magnet hunt today to see if I can find some.
Thanks for all your hard work!
Be waiting for your next video guys!

@Jbignes5:

I am looking forward to seeing you experiment with what you suggested here.
Unfortunately i dont get what you describe with the start-up tube.

Have a look in jonnys first video and you will see how much power you have to put into the initial spin of the magnet to get it going.
I personally can only get it going by having it flat on the lid and with both hands pushing the edges into a rotation real hard a couple of times until it starts up.

Restriction of the magnets movement is detrimental to the induced voltage of the pick-up coils. Jonnydavro and myself agree that it is helping the output to have the magnet bump into the coils occasionally.

I have tried restricting the magnet by putting a carboardring around it and it has most of the times killed the rotation, since it will try to fight its way out of the confinement and then go into a circular rotation around the edges.
When placing a small wire on the lid, i think the magnet will most likely just jump over it or make it fall, there is a lot of kinetic energy in this thing.

[Jbignes5]

I understand

I certainly agree with you not having the unit in front of me to test my theories out. but I will do whatever I can to replicate it on my end then I can show you better what I mean.
The tube is just to keep the magnet upright. With you left hand hold the tube and then insert the magnet into the tube. See if the magnet spins up on it own. If not try spining the magnet with your right hand while the magnet is still in the tube and then lift the tube over the magnet. If the magnet spins by itself to a degree while in the tube it might help start the magnet without having to lay it down. Making the magnet start easier being upright in the tube already. This could also be done with a plastic tube as well. But try it with the paper tube first and see if it works before hunting down a plastic tube.
Like I said I am missing a lot by not having a complete setup yet so these are only suggestions until I can get my own rig working.

[Xenomorph]

I think i understand now what you mean.
The thing is that you wont be able to spin the magnet forcefully enough while in the tube. You need to give it at least a 25 Hz rotation frequency before it kicks the circuit enough to oscillate. The circuit does not oscillate on its own.
It is the magnets rotation that starts it. And i can only manage double-handedly to give it a high enough rotational initial speed to get it going. The tube solution would be impossible with one hand only.

Jonny's great low amp circuit= A 2.5v/10ma spinner

@ Jonny----Thanks for the tips on how to get the amp draw down. I followed the circuit that you posted at the beginning of the thread and it worked great. Sephiroth--thanks for the tip on the coil before the Bedini coil that helped also. Here is the video of my sucess today--

I tried to charge a 9 Volt battery off the pickup-coils/cap:

YouTube - Charging a 9 Volt Battery

The charge turns out to be fluffy though
Cap discharging to batteries is a science for itself.
I assume i need much higher capacitance caps to get a strong charge onto the batteries and more efficient pickup coils, so the rate of discharge is fast too.

The reason that i do not constantly connect the coils to the battery or a load is the Lenz Law effect. It will essentially slow down the magnet too much, so that the resistance at the transitor base has to be lowered to keep the magnets rotation high enough to not stop. That in turn raises the amp draw too much compared to the power picked up at the other side.

@ Jonnydavro: Here is the experiment you asked me to do: YouTube - Different Coil Positions

[jonnydavro]

@Xenomorph.Thanks for doing that test.I was kind off hoping it would capture more than it did, ohh well
@Lidmotor.Thats more like it I think that third winding is genious.Can't wait to see if you can get it going on your SEC.
@ All.Today i tried adding a slave coil to see what would happen if i pulsed the magnet from both ends.The results were the rpm's seem to be higher and the pitch/sound off the motor increased but this would need checking with a tachometer.Here is a pic and a vid.Regards jonnydavro
