One magnet no bearing Bedini motor

[Xenomorph]

I had the idea of puting a magnet in the center of the air coil and having it fixed at two points with two sphere neo magnets kinda like the one bearing kind and have it suspended in the coil should increase the voltage

It has actually been done with spheres rotating inside coils with such high speeds that friction becomes irrelevant. I am not sure that this would increase the voltage unless you tilt the coil by a certain angle, which has been demonstrated to maximize the voltage as the cylinder will stay on axis and the spheres can freely rotate around 3 axises.

I have no aircore coil available that has an inner diameter large enough to fit the rotor magnet inside and allow it to tilt and am too busy with other projects to make an new coil that would allow that, but maybe someone else will try it.

Hi,

Can anybody answer this one....

I have finally got my standard bedini circuit to work, either as a rotary disk with magnets attatched or as a single diametrically magnetised cylinder as in the "one magnet no bearing"....however,...

when i use a coil that has either nails or welding rods as the core it works fine...... when i fill the core space with magnetite ( black iron oxide FE304 ) the motor does not spin at all and it seems that the circuit self-oscilates at as fairly high rate.

Thanks

ok, lowered the resistance on the base and its flying

Another way to spin the rotor---Hall Effect Sensor

I got a Hall effect sensor to run the magnet rotor using a very simple one transistor circuit and a single winding coil. Here it is----

Hi Cooles,

when hanging your rotor like that there is no need to hold it at the bottom
a strong donut magnet will keep it straight for you
whereby there is also less friction
like ive done here YouTube - JohnnBlade's Channel

now i am running my rotor half in the coil but nothing else to hold it

Hi All,

Im still working on my Bedini, but i dont know now what to do whith all this power, i have already blown up some small light bulbs, seen big sparks
and its still running now for 2 days

these next comming days i will not be able to work much
on the Bedini project. im getting operated on my leg (to remove 3 titanium bolts - mayb i could use that as a core for my magnet )

my Bedini is still producing 40 - 45v stable, and loading all my caps
here is the vid again YouTube - One magnet No Bearing Bedini motor - 2.6v in - 31v out - JB in the vids it reached 30v, but it will climb, it only takes a few seconds to get that voltage

in time i will try to see if i can get it to selfrun on its own power

im out for now, ill be making new plans for the Bedini while being under narcose

everybody keep up the great work

Nice work Lid, your amp draw is really minimal with this design. Capturing the back emf may be enough, but how about some direct generator capture with a bigger coil around your rotor. The earlier experiments with the degaussing coil are interesting and may produce enough amperage to get the job done for you given the greater momentum and field strength of your cylinder motor and the low amp draw of your hall effect driver circuit. You might be able to put it together quite simply like so...

[Xenomorph]

@ Jonny: I have tried 2 rotors and a single rotor and i can in no spot around the
coil measure a negative amp-draw, which does not mean that there might not
be such a spot or phenomenon. How did you measure the current? With 1 ohm resistor or amp setting on multimeter?

I have also replicated the wire diameter and winding ratio that Gadgetmall is using and there is no feedback to the source occuring.
However it is really possible to run on 0.8 to 1 mA with this coil, which would have been impossible with my first coil.
This low current approach to self-running is actually not very useful, except when you wanna make a self-running toy, but i guess you would not be able to charge anything efficiently with a rotational speed of 200 RPM, because low amps means low speed always.

@JohnnBlade. Did you actually use that conrad spindle right as it is off the shelf or did you slam some new wire on there?

@Lidmotor: Do you know how much voltage the hall sensor you use puts out?

[jonnydavro]

@Xenomorph.Thanks for trying. I am running my motor on 4.5v as it needs to get up to quite a high speed before i place it right up to the coil.I have refined my technique and now, i get the rotor up to speed on the top of the coil and then drop it down the front of the coil,i can make a vid of this if you like,this way it gets into position quicker and i am seeing negative currents of 30mA and higher.
I am measuring the currents with my ampmeter in series with the positive input like normal but when i move the high speed magnet into position it goes negative.This is a real negative current as i have placed two diodes after the ampmeter.One forward and an LED backwards.When the meter goes negative,the LED lights.
I have also done some more tests and i am begining to understand i think what may be happening.First of the voltage is coming from the coil and the return path is via the transistor's emitter.I know this as i placed a forward facing diode after the coil's primary winding connecting to the collector and it blocked the negative pulse.
I also put a diode in reverse accross(white stripe towards the collector) the transistor and the negetive pulse still occurs so the induced voltage is comming out of the coil,through the run battery and back to the coil via the transistors emmitter.
This is what i think may be happening.When i place the magnet sharply in front of the coil's,nearly touching,the magnet is inducing a high consistent voltage in both power and trigger coils.The transistor turns on but as the voltage induced in the primary is high,the voltage in the trigger coil is high due to transformer action and not just a spike so the transistor stays on and this slows the magnet but as the magnet has a bit of kenetic energy it is still inducing voltages in the coils and this voltage goes around,through the run battery,through the transistor's emmitter and back to the coil.I am not sure what the reverse breakdown voltage is of the TIP 3055 and 2N2222 as these are two i have used but it goes through a diode placed accross the transistor as well.
One other thing.My bifilar coil is 1:1 , 26swg for both trigger and power winding of equal lengh .What do you think?

Regarding Gadgets motor.Have you managed to find an sk3606 diode as i think this is the key to his feedback as he says he has tried loads of other diodes and feedback only occurs with the 3606.His coil design is also good if you can run a snake egg on 0.8-1mA or are you taking about a cylinder as my coil will run a cylinder at 1mA and a snake egg at 4mA.This is @1.5v.
He has also reported it as a confirmed self runner at ou using caps so i hope he comes over here and updates us to how its holding up after prolonged tests.
Thanks Xenomorph.Regards jonny
@Lidmotor.I really like your new design.Using just a single coil is far easier than winding them and if your choosy,you should be able to find coils with both ends visible so they can be used straight of the shelf.Nice work Regards jonny

Videos are always more illustrative
So you are saying that you persistently get negative current results?
So what aspect of your setup do you think is mainly causing those currents? The double magnet?
Does that charge your source battery up a bit?
The diode test you made make the signal flow clear, good work
The coil i am currently using is different
Its 3300 turns power coil and 350 turns trigger coil both 0.4 mm wire.
You have both your magnets magnetically alinged exactly equal right?

@Xenomorph.The Negative pulses last for a second or two and the rotor slows,i then speed it up and i can do it again.The battery rises in voltage on each negative pulse.This works just as well with a single magnet rotor so its not the twin magnet rotor.
Technique is important for this,you have to get it infont of the coil quick and also my coil is a lot different to yours being 1:1 so the transformer action in mine is high.With this coil on another motor i have,it will open the relay coil in the trigger circuit when the motor draws over 200mA so the coil may be important.

[Xenomorph]

Hmm, maybe to set it up (somehow ) like a pendulum, that the magnet will swing itself in regular intervals into that position could be an application.
I have a typical Bedini coil 800 turn 0.5 and 0.8 mm bifilar (my first coil).
Ill check it tomorrow, however i know i did some tests like this before and have not seen negative impulses.

Sounds all very interesting ! Cool

[coolesrat]

might be to much

ive been thinking about stuff like this for awile but i really dont have the parts or the time to try them , but i had an idea of maybe trying a half iron core coil with a plastic coating so the sphere neo magnets can run freely and the air coil in the mid of the pic is just an extra dont really need it but i thought maybe it would be good ?? tell me what you think it was just an idea

i spent sometime working on this crap drawing

Hi Guys...

Just a quick note from scanning the tech papers. From the University of Arkansas paper on magnetic vortices as computer memory:

"They found that switching the direction of the vortex from clockwise to counterclockwise produced a positive electric pulse – and that switching the vortex in the opposite direction created an electric pulse with a negative sign. The resulting electric pulse can thus serve as the fingerprint indicating that switches of vortices did occur, as such a switch is difficult to directly observe."
I will edit this to add more as I find it but they say that a vortex is definetly there in the nano scale. Now why wouldn't it be there in the larger scale?? Hmmm.

Hall sensor spinner

@el- tigre-- Interesting idea about surrounding the rotor with the induction coil. The degaussing coil idea still has me interested because it performed so well. I'm still learning about the Hall sensor and seeing what it can and can't do.

@ Xenomorph--- I have not measured the voltage coming out of the Hall but it isn't much. It is just enough to tickle the base of the transistor and make it switch.

@ Jonny D---The single winding coils that I am using are off the shelf ones that have that little "start" wire sticking out. You have to be really careful that you don't break it off but it means that you don't have to wind the coil. Just hook it up and start spinning. That saves alot of time.
