One magnet no bearing Bedini motor

[synchro]

Hertz and magnet spin rpm.

The range of full sine wave AC pulse that will power a spinning magnet in the sound spectrum, is from around 10 Hertz to 10 Khz, The high range Retrod1 reports the magnet spin dropping off. There must be a large dead gap that reawakens at higher frequencies, becaue the full sine wave once again picks up and reactivates the spin up in the coils mega hertz resonance range. Experimentation needs to be done to find out what the lower end of the mega-hertz range is, that the spinning magnet looses its receptivity to the broadcast signal. Does anyone have any idea what the lowest megahertz spin active broadcast frequency might be? I believe it's possible that there may even be more then two ranges, perhaps mimicking some sort of Barkhausen scale, right up into the gigahertz micro wave range. It might be interesting to see what would happen if a hematite ceramic magnet sphere were spun up inside a microwave oven, with a bedini coil in resonance, near the door, then to switch the oven on and see if the magnet accelerates. Wear your helmet for that one!

@Rave154.Hi.I found a bit of time to have another look at the wireless plasma globe experiments and i have done some tests with some interesting results.
This is what i did.I set it up with two Led circuits and a tinfoil screen which i can move in front and inbetween the two circuits like so-
O screenpos1-circuit1-screenpos2-circuit2.
When the screen was in position 1,circuits 1 and 2 amp draw increased.
When the screen was in position 2,circuits 1 and 2 amp draw increased but not as much as position 1
With a tinfoil screen in position 1 and 2 it seems to relay the energy like pass the parcel and more energy is being tranferred further.
I don't know what effect this is having on the amp draw of the globe as i was running it off an adapter as my battery has died but a very interesting and easy experiment to do.Regards jonny

not sure

Hello,
Im new to the forum but have been reading as a guest for some time. I have replicated the ssg and feel I have got working correctly. This thread has really gotten my attention though. Good work folks. I have a couple of questions and if theve already been answered I appologize.
Ok I tried the one magnet snake egg. Works fantastic. I used just the standard bedini setup with 680 ohm base resistors. I have a quadfiler coil. (yes three transistors) I basically modeled the setup on Ron Pughs energizer.
AIr core, and I dont know the number of turns but each winding was a quarter pound roll of 22-24 awg wire. I dont have ANY other resistors on the trigger except for the ones from the base. This snake egg is terribly fast. I put an AM radio next to it and the pulses are at such a high frequncy that they almost sound like one long pulse.
So does anybody elses one magnet work BETTER than it did with a standard rotor? Yes, I have a better charge rate than I did with the rotor. Charge Battery goes up faster and holds at volatage much better than with a standard rotor.
I dont have a scope just a standard handheld meter. And im sure it isnt accurate but just to give myself somekind of reference point i disconnect the charge battery to see Voltage and Im outputting 40-50 V. When with standard rotor I saw no more than 25V. Now when I do this the rotor speeds up like I said. When I reconnect the charge batt the rotor some times speeds up AGAIN like it shifted gears or something! Is this normal? At this point I dont feel that the charge rate is any better though, THe charge batt. stays about where it was with no change up or down.
Ok I was also experimenting last night and I noticed my coil had a very quiet but high frequncy hum to it. I had to have my ear basically 3 inches from it to hear it. It was self pulsing. I say pulsing because when I put a magnet up to it it would vibrate the magnet in my hand. But I also noticed that the machine was charging the battery while it was doing this. BETTER than It was with a magnet on the coil. Normal? I can run multiple LED's, or one of the extra neons I have. or a little motor that I had laying around. Now with the motor I had more torque to it than I have ever had from it before when connected to my Bedini in any other configuration.
When disconnected from charge batt the voltage reads at 70-80V in this self running mode.
if anyone could point me in the right direction I would appreciate it guys. Thanks in advance

Hi redrichie You are the first i know off to run a snake egg with a quadfilar setup so comparable results may be thin on the ground but your results are very encouraging as it sounds like you are seeing a 50% increase on your output but you would also need to compare the amp draw for both rotors.That said you may be able to increase efficiency further as you are limiting your control over the motor by using just a 1k pot in your trigger circuit if you are using the standard Bedini circuit.I use a 10k pot on my snake egg(100k with the 6mm sphere's) with both air core or cored with welding rods depending on if i want a low voltage/amp draw motor or hgh rpm's with the rods but i see the speeding up effects you see and this also coresponds in a drop in amp draw but there will be a point where charging/amp draw is optimal and a bigger pot may help find it.I think the circuit i use is on the first page off this thread and it also allows for further energy recovery options.
Regarding the one magnet Bedini's performance.I find it charges and spins faster than the standard Bedini's i have built but there are some great builders out with some amazing motors and the right equipment to compare so i will leave that to others to decide.If you check out this Builders utube channal.He Knows what he is doing and he has made a comparison.You may find it interesting.
YouTube - smw1998a's Channel
Regarding your coil humm.This happens when you have a high resistance on the base and the coil goes into self oscilation and this mode is used as a rotorless battery charger like you have discovered.I think there are a few threads on this forum about this and i think theremart has built a good one so he may be able to help there.
Anyway,thanks for dropping in and keep us informed of your progress.Many thanks.Jonny.

[redrichie]

Thanks,

THanks for the welcome. Umm, I have no pot whatsoever on the system. I played with the resistors on the base to get a balance of charging and consumtion. THe 680 ohm just seemed to work the best for this system. I wen't up to 1.5k Ohm (hard wired resistor not a pot) on the base and the thing sounded like a jet trying to spin up but my charging was almost non existant. Ill go get a bigger pot and see how it works. I appreciate all the open sourse info that the people here offer.
One other question for now. I watched Jamie B put a cylinder Neo in the center of a Rodin coil and it spun. However he didnt have it attached to a shaft. More or less it was just a rod and the magnet spun on it. Has anyone tried a design like youve done Jonny with a shaft with a magnet bearing and a Rodin coil. And how is your design coming along? Yours is fantastic especially if you can get sattelites to spin off one central rods input. HAve you thought about having other rods horizontal along side with yours that are only for sattelites. Rings not spheres? as long as all your rods were not magnetic it should still spin the same right? Thanks again for the info.

@redrichie.Try and use two pots,a 1k and a 10k in series.Have a look at my circuit on page one and you will see a relay coil in the trigger circuit as well which sephiroth discovered reduced amp draw and i use his idea on all my motors.You may already have the correct values for your setup but its something else to try and it will give you more options.
Regarding the levitating motor.I have not heard of anyone trying this with a rodin coil so it would be an interesting experiment and i think it would work really well given the centred magnetic field in the rodin coil.
I don't see any reason why levitating satellites wouldn't work and when i have got this motor where i want it,i will try it.
You ask how the levitating motor is going.I have done a little bit of work on it and have reduced the friction on the one contact point significantly by adding 4 more base magnets so now the rotor has a near neutral position as it is being pushed from both side's now but i have some other things i want to try with this yet so stay tuned.Happy experimenting.Regards jonny.

pikup coil question.

Regarding pickup coils. When reading through coil winding for wind generators a while back I remember learning about the differences in Star and Delta wiring configurations. Has anyone else looked into this. Not sure of the amount of torque these little magnets have but if a load were applied to the pickup coils wont it drag down the system? or since the satts. are only connected through a magnetic link will it just slow down the sat. in question? either or. If the magnet does slow down wont one of these configurations have a benefit to us. Wiring in the star config puts less drag but less current supplied. Delta is the opposite.
Again with Jonny's machine a circle of eliptical coils about the length of the magnet could be used in a full 360 deg around the magnet or magnets on the shaft, ( not incasing the magnet like sticking it inside of an air core but having 3-5 coils horizontal to the magnet) IF you were to put more than just the drive magnets on that particular shaft. if there were some cogging couldnt it at least be compensated by a flywheel with some mass to keep inertia up? Please correct me if im wrong. Im not an engineer by any means.

started testing Rodin coil

WEll I dont have my neos in yet but I tried a few experiments using a Rodin coil. Please forgive some of my ignorance as I am teaching myself electronics on the fly.
I have from what I can tell the standard bifilar Rodin coil. (if this is wrong and I need a third winding someone please correct.) My BEdini Is using a quadfilar standard coil, aircore. I removed 2 of the windings from the bedini circuit and replaced with the 2 from the RC, (couldnt get the snake egg to start all the way up using the RC as the only coil since the magic happens at the rim and it recessed into the coil) Basically making my standard coil a bifilar with one push and one trigger. I used the RC as slaves. just with the bifilar it was as you have come familiar with. I then hovered the RC over the snake egg and it sped up just like it was with my standard quadfilar. charge rate the same and voltage maybee 1-2 Volts higher than normal. If I flipped the RC over it would stop the snake egg almost instantly. Only on side pushes, the other side seems to kill the circuit. Nothing else spectacular to report.
I then placed the RC on top of my quad and just used it basically as a solid state device and here is where I got something a little different. I use an A.M. radio since I dont have a scope. Im pretty used to the sound that the device makes regularly but with the RC on top I could hear a very distinct background sound that would reverberate up and down seperately from the normal sound. (kinda sounded like I was sending messages to an alien race or something!) very weird sound kinda hard to put into words if ya know what I mean. If I moved the coil it would squeel and moan in different pitches as I moved it around the standard coil. This sound came from the RC itself very audible. Charge rate and voltage the same as with the standard setup.
Just out of curiosity I removed the RC from the circuit. I placed it (in series? not sure here maybe someone can tell me) I tied the leads from the RC as follows: A1-B1 together and A2-B2 together. a1-b1 connected to one side of my Bedini output the other side of the RC now became the output lead. My normal voltage in resonance is about 40 Volts with the RC in series(?) I out put 95V. Did I esentially make a transformer? would this be normal? I would test my self if I had another bifilar regular coil and replace the RC, but I need some more wire. you can never have neough of that stuff. Sorry this is long winded and thanks in advance to help out hte new guy.

@ Redrichie

Interesting using the Rodin coil! Also the noises you hear are out of this world... Could you make a video?

About applying a load - As far as I know the magnet is simply more mass for the oscillator to oscillate, as well as being a trigger, however I don't think a mechanical load could be applied to this successfully, unless it was very light. I may be wrong, and to my knowledge no one has really tried this yet... but the torque for these types of spinning pulse motors are low. If you add a pickup coil with a resistive or inductive load, then the rotor magnet slows down, but if the pickup coil has a capacitive load, it will not slow down. All you need is a timer to discharge the cap to a real load, and then put it back on the pickup coil circuit.

Well come to think of it again, if you were to apply mechanical load on and off, when the magnet is slowing down the charging would increase and so would amp draw, and when load is removed speed would build back up again. So its possible, but direct shaft might not work as well. The whole trick is to be in resonance, and anything that throws it off of resonance needs to be worked out.

Hmm.. Maybe if you had a room sized rodin coil and a trashcan sized magnet then you could get some real torque!

[geminitric]

I have a lot of torque coming out of mine now - but am using a cylinder neo on a shaft now. Going to hook up pulley to another axle as a generator, see what happens. Definitely have enough torque for it with my current setup.

setup

Nice job. Are those "air bearings" at the end of your shaft or regular bearings? Im working on an airbearing myself, got in the neos and I didnt get a large enough tube for the ends so it didnt quite work out. But I had a few small bearings laying around so i got it up and running. rotates very nicely, Using a 2' carbon fiber shaft. Even at less than a .25" the stuff is very strong and non magnetic so no interferance from it. Have 2- 1" diamet. magnetized neos, one for the quadfilar coil setup and the other to start testing of a pickup coil. Any suggestions from anyone on a pickup coil for the 1" neo tube? I know some had real good luck with the hockey puck shaped coils. I tried a solenoid coil I had handy and it really slowed down my system and only produced about 3-5 volts without bringing to a grinding halt. Thats with only the meter hooked up to it, no load. So im thinking larger air core, prob about 1" core but the puck shape. Whats a good gauge wire for the pickups? all suggestions welcome.

Hi Jonny,
I prepared this pic of my notyetfunctioning-egg-spinner-bedini because you suggested that if I were to do this someone might pick out my mistake.
I am not sure how well it will show up, but here it is.

I ordered some magnets including spheres and diametrically magnetized cylinders.

I am now getting a hot coil and a clear response from the egg that there is something magnetic going on, but no increased spin.
That thing going from 3 to the nails is a loose piece of tape. The nails are not in there in the pic.
Also I couldn't fit the 6 from the coil and it seems that the 6 coil is a 3 but it isn't. The coil 6 goes over to the the brass nail where all three wires are soldered.

So, here it is and thanks for the offer of help.

[jonnydavro]

Hi Jeanna.From your pic and description i noticed 2 things that may be a problem.I think your coil may not have enough turns on it.I use two 250 gram rolls of 26swg,1 for the trigger and 1 for power and just wind both spools onto a third until all the wire is used so 500 grams of wire in total.I don't know what the awg equivelent is and also you state that your coil is heating up.This could be caused by a short between collector and base as as the magnet is not spinning the transistor should not be on so thats something else to check as the coil should stay cool..
Also i would leave the 20k pot out until you get it going just in case its going solid state on you.
Anyone else who can help out here please chip in Regards jonny.

[Joit]

Same guessing here. When one Wire/Coil goes hot, it has only different Ohms.
What i have seen is, they should match, or at last be max about 9-12 ohms away.
But else, for the triggercoil i did take once very thin Wire,
what still did match with the Impedance, because it did reduce the Current,
what arrived at the Base from the Transistor

Jeanna's Bedini circuit

Hi Jeanna,
I have been quietly following your progress and I agree with Jonny that it looks like not enough wire on the coils but it might be something else. My experience is that when you get a hot coil there is a wiring problem or the transistor is fried (shorted). The connection of the four coil ends has to be right also or it won't work. Start and finish points are critical. The base resistance, like Jonny said, doesn't have to be anything but a resistor and it will run. On one of my tiny circuits I don't use anything and just let the trigger pulse go straight into the base. See if your drive coil will push a magnet by hot wiring it to a AA. If it doesn't move the magnet then you might have to add more wire. I use only neos on my motors but of course the snake egg is a Hematite. On the trigger coil, if you wave a neo by the coil the transistor should do it's thing and work. You can test that with a battery and a volt meter. If nothing happens then there probably isn't enough wire on the trigger coil or the magnet is not strong enough. On my first "Lidmotor Bedini coil" I was at the edge of it working or not working and lucked out. I understand what you are going through. It is frustrating. Hang in there.
