Slave Coil Windings

I am about to wind my slave coils and can't seem to find a clear post on this thread that tells if they are wound unifilar, bifilar or even possibly quadrifilar.

I found this quote by John Bedini:
Quote:
I have moved the pole piece out of the core so that the right angles meet at the shield, so what I'm doing is causing a delay in the magnetic field by closing it in. I said that four coils are wound on one coil form two #15 wires and two #18 wires. The # 18 wires are control wires the two 15 wires are power wires, look up the definition for Mag Amp. understand what a Mag Amp is and how it control's energy, self biased inside the coil.
It seems to me that it would be most likely that he used only 18 AWG on the slaves since John states that the 18 AWG wire is being used as the control on the mag amp setup of the main coil.

I would really like to get this right the first time as money is an issue.

1. Are the slaves unifilar or bifilar wound?

2. Does anybody know if each individual coil strand has its own Bedini/Cole half bipolar switch?

This would not make sense to me since the coils would need to be paralleled with the least amount of resistance to act as a mag amp. But it was still a question worth asking for clarification purposes.

Now as I advance the timing till the trigger happens when a magnet reach the middle of the right slave coil , I only get half the positive going sine wave during off time before the next trigger pulse. Like Jeremy explained. Only voltage. The current is lagging by 90 deg and the next trigger pulse occurs before any current flows.
This gives me much better output and the rotor also slows down a lot.
Towards the end of the video you can see clearly how the sine wave change as I adjust the timing.

Woohoo!! Awesome!

I knew you would be the one to do this!

I think you might have meant LaserSaber. They last posted on the Joule Ringer tread.

Lidmotor.
I did not receive the PM try it again sorry for the inconvenience. Hope progress is progressing.
I'm spending most of my time building a magnetic solid state relay as that is what is needed.

But I do want to talk to you, about taking this big ferries wheel machine and planting it into the ground. I will build another one if I must with earth coils. but I just have a few questions about this as I did use the Stubblefield coil for transmission. I think it can be done right now if the switching works right.

SSrelay

We built a solid state relay using a hall and coil way back. we took an 8 ohm coil w/ welding rods - the usual SG type, placed the hall on one end. got that thing to self oscillate but could not slow it down, we started messing w/ chokes and fried a few things before we decided it was I little to advanced for us at the time.
will have to give it a spin here, now...
wow! Stubblefield in the ground for transmission! remote Ferris Wheel?

Minoly,
The switch I'm building is not the same thing I'm just waiting for the germanium blanks to come. I already have the silicon Fet chips I need very lower power device .5 volts to .75.

Mag Amps

Hi John B,

I have been researching mag amps and I think I know how you have the main coil hooked up as one.

Can you confirm that one of the #18 thinner windings is used for DC bias, the other #18 thinner winding is used for the control wire, and the two #15 thicker windings are wired together in series and in phase?

Just a bit of info... not sure if its helpful.

If I take a coil and my LCR meter and put the LCR meter on the winding and then take a magnet and swipe it over the coils end, I see an increase in the measured inductance of the coil, regardless of which side of the magnet is used to swipe the coil.

Thus the movement of the magnet, based on that observation, works to increase the inductance of the coil.

An applied power pulse on that strand or a cowound strand reduces the inductance somewhat, while shorting the same cowound strand brings the inductance down to near nothing.

Just some comments on observed indutance changes based on the noted changes above.

Regards,
Gene

John Bedini states that all of the coils are in parallel. Since the magnets would be saturating the iron cores of the slave coils first, they would be creating a pulse of electricity through the master coil. To my understanding, this pulse would cause the core of the master coil to become somewhat saturated and the inductance(L) would drop. This might be what John Bedini was talking about when he referred to the use of a mag amp.

Once the mag amp effect is at its peak (inductance becomes lowest), the coils would fire from the half bipolar switch. The mag amp effect would cause the coil to charge in a low inductance state (Charging would happen quickly) and discharge in a high inductance state (High voltage spikes should occur) after the mag amp effect has diminished.

Eric Dollard has always spoke of the importance of changing inductance or capacitance with respect to time to cause the "synthesis of energy".

However, I am a bit unclear on the directions that the coils are to face. Since there has been so much speculation as to what is really going on, I've gotten lost in all of the non-Bedini produced diagrams.

Since all of the magnets on the rotor are north facing out, the only way that the two slave coils could create this "pre-pulse" of energy is if they were being repelled from coil being energized since they would have to have already passed TDC of the core. This means that the slave coils would have to be pulsing a north pole towards the magnets, and the master coil would have to be attracting the magnets with a south pole.

If somebody that was at the conference or that has a better understanding of what is being said here on the forum, please fill me in as I am just trying to understand what is actually being said.

Some scope shots of the ferris wheel free-wheeling would be interesting. It looks like the sine you show is slightly shifted to look a little more like a sawtooth wave. Is that perhaps why bedini is using neos to bias the flux of the larger ceramic? to help shape the wave being shared by the rotor? It would fit with some of the waveforms hes put in the FEG book.

Thanks for sharing the scope shots.

The video you shared is very nice... it shows that by playing with the hall position you shift where in the sawtooth the switch is turning on.

Now if you just knew at which point in the cycle per pulse you are supposed to switch at..

Is there any better performance in any particular area of the sines switching where you note the switching is more powerful or useful? Does it run better or worse in any particular part of the triggered pulse?

Thanks much for sharing!
Gene

Howdy John K,

I built me a magnetic amplifier to learn and study from. Its here in this youtube vid I put up last friday.

YouTube - 1000 Watt Magnetic Amplifier running 500 watts of lamps.

A basic Mag amp needs one AC winding and one Control winding which is controlled with DC power. (or so the mag-amp book says.) However theres a homemade mag-amp site on the sparkbangbuzz site that is what I made use of to build my mag-amp using 3 of the same model 1000va transformers.

In effect only one of the transformers is the load transformer. The other two transformers are used to create an asymetry on ONE side of the output load transformer. The other side of the output from the load transformer goes directly to the load. The two transformers are wired up on the other end of the load winding in series and finally out to the load. The DC bias of those two trafos (short for transformers) is then wired in "BFCEC" which means bifilar common end connected, which nulls the inductance of the two windings put in such relation or would if they shared a common axis and core, however in this instance it just seems to make it so the bias winding can't be shorted to cause the AC load to be powered. If you short the bias winding and the load gets power, then the DC bias windings are connected wrongly.

The interesting thing about a magnetic amp is that it "switches current". The voltage sine wave is always present on the load trafos output winding so that if you put a resistive lamp load over the winding, the sine will go flat as there is no CURRENT there to keep the sine from sagging. What happens if you use a cap as the load? I don't yet know, but will soon.

The idea is that the cap won't act as a short to the load so the full sine should still be let thru but the rate of charge would be based on the amount of current needed to bring up the rated farad capacity of the cap to the volts being output from the load trafo.

This then brought me to think about chopping the DC pulse bias. So I did that. I found that I need an ON duty of about 98% to get full output from the trafos load winding. (this without the cap on the DC bias to hold the charge, which I think might change the DUTY a little ... hopefully.) I need to add a cap there and see if it doesn't allow me to reduce the ON duty further while still being able to retain the output from the mag-amps load winding at full voltage. (albeit chopped).

So Chopping the DC bias on this mag-amp made little improvement over the power needed to turn it on or off. I am almost just as well able to use the DC bias in constant on as theres not much savings in pulsing/chopping the DC bias pulses if I still want the full rated volts output in the sine.

Thats my study of the magnetic amp I built on my bench so far. Thoughts/comments? how does this apply to the ferris wheel setup?

Seeing as the SG is a rotary magnetic amplifier that switches on a single polarity, perhaps the field shaping of the rotor is getting the waveform to trigger the drive circuit just right so that its better able to work with the now biased sine waveform that appears to be emitting a single polarity ramped over time versus the sudden drop to zero perceived as the field reguaging function on the typical SG perhaps? The balanced sine wave has the same time to drop to zero as it took to get from zero to the peak. The biased waveform presented in Nvissers vid shows that the neo has altered this sine into more of a sawtooth wave.

Good stuff... Hope I'm not off-topic sharing the mag-amp I mocked up.

Take care all,
Gene

John B,
my post does kind of read that way - did not mean to imply we did what you are doing. just that we used a hall relay as one might use a reed relay. to turn things on and off. Very useful when trying to time these sensitive devices.

.5 volts, not sure what you are using it for, but that will help to get CFL light for nothing over on the Joule Ringer. we have ours oscillating like crazy, voltage climbing for the last 2 hours, disconnect the battery and it shuts down - go figure.
YouTube - min2oly's Channel

I'm sure it's all fluff voltage at this point - we'll keep at it. maybe if we clean up our wires... that would mean a run to the store for more soldering tips.

Howdy John B,

Sounds like you are looking to use the flux of the magnets passing by to activate this magnetic relay maybe? I see a magnets flux as pure current... converting some of that to voltage needs an inductance. Low resistance high inductance coils like the SG coils seem to provide just about that voltage for turn on and the full current to drive what sounds like a custom die germanium transistor to actuate the relay.

You looking to make it latch? Or just a momentary contact relay?

I spent a little time looking for relays I could hit with a small DC pulse to activate them which would latch and unlatch from the unipolar dc pulse. The problem is those types of relays don't seem to get very big in terms of power handling capacity.

Will be curious to hear how it goes, hopefully it aligns to your vision.

Take care man,
Gene

How can I help you. did you get it running? I would study my coils as I said the coils are two different impedances and that the coil must be big in the center double the outside coils I could measure them if you want.

Hi John B,

Yes, I got it going. Just the main coil for now as I want to master the mag amp side of it before I add the slaves.

Here's a quick video of where I'm up to.

YouTube - Bedini S1GT

I have an idea I want to try with the Mag Amp in that the two thinner windings are used to a) bias the coil at the ideal operating point and to b) use the winding to control the inductance (or permeability) of the coil for maximum and efficient power transfer through the power windings when the Bedini/Cole circuit fires.

I'll keep playing around and let the group know how I'm going. I may go digital with the switching on you though - 1 hall input can give me the flexibility to adjust the Mag Amp coil bias, as well as the power winding timing and dwell.

I was just wondering of the 2 thicker windings of the centre coil are connecetd in series or parallel and if in series, are they in phase? My gut tells me they are.

I will keep studying and testing.


John K.

@all,
Yes the inductance does change when the magnets pass the pole. The one thing that you can not do in the machine is twist the wires. Now each wire in the main coil has it's own resistance so this is offset a little when it turns on sort of like a mag amp but pulsed DC or more like PWM because of the switching so I had to sit and tune it for maximum power low RPM.

This is a very tedious to do as if I did not get just right I could not self start the machine. No one posted a Video of me showing it at the convention yet but someone out there has it. When I would start it from a dead stop it would accelerate backwards and slam agents three magnetic fields and dead stop then leap forward right up to 16RPM's that is how I knew I had the timing right. You all have done excellent work on this group. But now I'm going to do something I always wanted to do with a new machine just like this we must make it run with no input. Great group glad I could be here.
John B

Base coils

John B,

You have said very little about the (slave) outer coils except for the impedance being half that of the center coil. Are the slave coils made up of the same number of windings as the center coil? Is the length of the (4) windings in the center coil all the same length (4000 turns)?

Also, question in regards to the size of the cores. Would you suggest that the cores be bigger than the width of the magnets? We have 6"x2" magnets...should we make them at least 2" diameter or bigger?

Thanks for your continued guidance!!!


Brent

John K,
Just use a little DC bias on one winding but reverse, you must choose the resistor, may also require a capacitor in series. I have been watching Chuck H at work with his machine I have not seen him charge the batteries yet but he can also tell you that it's not easy to tune. Just ask him he is on this group. Do not give up I did not learn this overnight.
John

Brent,
No the slave coils are 1/2 the impedance with single windings this all makes up a parallel transformer with different impedances This is very hard to explain but it's almost like having a time delay between coils as you can see this in the recharge output power. Three very YouNeak pulses of over 500 amps peak in one second.

Thanks John,

I think I get what you mean. If the coil is biased reverse then the coil will take longer to charge as it will fight the bias, but then when the coil discharges, it discharges faster and with a bigger "whallop" which means a bigger spike to the cap.

I will use a large rheostat or potentiometer to find the right resistance for the bias winding. The 2nd thinner #18 winding I will experiment with using in series with the bias winding and use the passing rotor magnet to generate current to influence the DC bias.

I agree with Chuck H that it is hard to tune, which is why I want to go with a PIC as a PWM and use the hall as the PIC input to be able to adjust the switching and timing digitally. I'm also thinking of Sziklai pairs switched by optos off the PIC in place of the MJL21194 & MJL21193 to do the power winding switching. Minimal loss and faster switching.

Gotta test these ideas on the bench though.

YouTube - 1000 Watt Magnetic Amplifier running 500 watts of lamps.

A basic Mag amp needs one AC winding and one Control winding which is controlled with DC power. (or so the mag-amp book says.) However theres a homemade mag-amp site on the sparkbangbuzz site that is what I made use of to build my mag-amp using 3 of the same model 1000va transformers.

In effect only one of the transformers is the load transformer. The other two transformers are used to create an asymetry on ONE side of the output load transformer. The other side of the output from the load transformer goes directly to the load. The two transformers are wired up on the other end of the load winding in series and finally out to the load. The DC bias of those two trafos (short for transformers) is then wired in "BFCEC" which means bifilar common end connected, which nulls the inductance of the two windings put in such relation or would if they shared a common axis and core, however in this instance it just seems to make it so the bias winding can't be shorted to cause the AC load to be powered. If you short the bias winding and the load gets power, then the DC bias windings are connected wrongly.

The interesting thing about a magnetic amp is that it "switches current". The voltage sine wave is always present on the load trafos output winding so that if you put a resistive lamp load over the winding, the sine will go flat as there is no CURRENT there to keep the sine from sagging. What happens if you use a cap as the load? I don't yet know, but will soon.

The idea is that the cap won't act as a short to the load so the full sine should still be let thru but the rate of charge would be based on the amount of current needed to bring up the rated farad capacity of the cap to the volts being output from the load trafo.

This then brought me to think about chopping the DC pulse bias. So I did that. I found that I need an ON duty of about 98% to get full output from the trafos load winding. (this without the cap on the DC bias to hold the charge, which I think might change the DUTY a little ... hopefully.) I need to add a cap there and see if it doesn't allow me to reduce the ON duty further while still being able to retain the output from the mag-amps load winding at full voltage. (albeit chopped).

So Chopping the DC bias on this mag-amp made little improvement over the power needed to turn it on or off. I am almost just as well able to use the DC bias in constant on as theres not much savings in pulsing/chopping the DC bias pulses if I still want the full rated volts output in the sine.

Thats my study of the magnetic amp I built on my bench so far. Thoughts/comments? how does this apply to the ferris wheel setup?

Seeing as the SG is a rotary magnetic amplifier that switches on a single polarity, perhaps the field shaping of the rotor is getting the waveform to trigger the drive circuit just right so that its better able to work with the now biased sine waveform that appears to be emitting a single polarity ramped over time versus the sudden drop to zero perceived as the field reguaging function on the typical SG perhaps? The balanced sine wave has the same time to drop to zero as it took to get from zero to the peak. The biased waveform presented in Nvissers vid shows that the neo has altered this sine into more of a sawtooth wave.

Good stuff... Hope I'm not off-topic sharing the mag-amp I mocked up.

Take care all,
Gene

Hi Gene,

Thanks for the Spark,Bang,Buzz link, for those who are interested in some basic mag amp stuff its well worth a look

You bet Ren.

I put a 330uF cap on the DC bias side to see if that would let me get the DC ON time below the 98% but it only reduced the heating of the transistor slightly. I'm not sure if using a larger capacity would make much difference.

Next is to put a cap on the output and see how that works as the load.

Take care,
Gene

Mag Amp

Hi Jeremy,

I've been studying and testing the Mag Amp, trying to figure it out.

A couple of questions:

1. Until now I thought the slave coils were in parallel with the 2 power windings on the main coil. Your schematic shows the slave coils in parallel with the 2 thinner windings on the main coil. Are the slave coils purely used to bias the main coil? (As a Mag Amp)

2. In the Mag Amp material I have studied it is advisable to set the DC bias of one of the windings to the "ideal operating point", where a small change in power in the control winding reflects a large change in inductance in the power windings. Is an LC meter the only practical way to measure the inductance of the power winding whilst adjusting the amount of DC bias?

Any other related information will also be helpful.

  • Take four wires, any size, but keep them same length and size for now. Keep this simple.
  • Wind three wires as a trifilar coil and the fourth one by itself. The trifilar will be the Mag Amp. While the separate coil will be CONTROL. MAKE SURE TO NOT LITZ THE WIRES OR THIS EXPERIMENT WILL NOT WORK!!!
  • On the Mag Amp coil, connect one power strand end to the top of the next power strand. This will be two power strands in series!! This will create high inductance on the windings!!! Measure the inductance of these windings and keep the LC meter connected.
  • Now short the third available winding on the trifilar and measure the series inductance. It drops!!
  • Now take the third winding ( control strand ), place it across a 9 volt battery and measure inductance.
  • Flip the polarity on the 9 volt. What do you get? A gigantic inductance rise or lowering of the series power wires depending on 9 volt polarity. You can swing the inductance either way dramatically with very little input.
  • Now connect the 4th single strand coil left to the third control winding instead of the 9 volt battery. This extra coil should be in PARALLEL to the control winding of the trifilar mag amp. Think of this as the impedance matched slave coils on the sides.
  • Take a large Neo and slam it on top of the slave control winding! Guess what, you control the inductance to the Mag amp coil very easily!!! Both up and down!!! This all requires an A/C wave to control the inductance!!

Why is mag amp technology a lost art?! It's beyond me. BTW, the early marconi stations were based on Tesla's work with intense grounding (bolinas county, CA) uses Alexanderson's mag amp work!! I find this very interesting. Read Alexanderson's patents. Some of the earliest work of mag amps.

So here is a proposed wiring of the Mag Amp with Slaves windings in parallel. I have moved the diode close to the switch.
There is still lots of room for improvement here. For example, I do not show the capturing of the reactive impulse from the slaves as well as the axle generator. But this is a good start for all of us to begin and understand the process here. Thanks goes to Vissie and Matt for the SSR potential inverted switch. This sche is set for 12volts but can easily be set to higher voltage inputs and outputs.



Now imagine the Mag amp coil is pulsed in low inductance and released in high inductance!!! A rotating wheel self biases the mag amp, and still only requires one switch from the input!!

Here is a simple timing of the slaves vs. master mag amp coil in CCW rotation, just to show this principle of variable inductance control from rotation.



Now everyone needs to see the scalar south (fake south) that is pointing out in between the neo-tipped weak northís. This is where the triggering of the hall switch needs to be. Since the neo is creating an asymmetrical large south compared to the north, the scalar south is going be very pronounced. Also the rotation of the neo causes the south field to cover a much larger area between the 22.5 degree sections. I or someone soon will talk about this later. This gets into geometry of the axle in generation mode to prevent lenz law!! Look at the sweet 16 diagram from John Depew that John posted, you should see the coils in the center now!! Also notice that the pie shaped barium ferrite magnets are pointing directly at these monopoles!! Ring the bell twice!! Look at the line at the 16 pole sun. We all need to see how to prevent lenz's law with the 10 coil axle.

I trust that this is mostly on the correct path John. This is by far the most important device to understand how to manipulate and make a man made flux field from Edís work as it is correct.

Hope this helps.

Hey John K

Where was that post from Jerdee at I've never seen it before.

Almost there!

John B,

Found several items today that will help Scott and I complete the bottom coils of our build. Found some great reels that are 10.5" wide with 3" holes for cores and found a magnet wire distributor here in Dallas, TX that has the larger (75-80 lb.) spools of wire. Cheaper per pound than the normal 11 lb. spools that everybody carries.

All we lack is to get over that last little hurdle of confidence to pull the trigger on a potential $1500 purchase. We both have different interpretations of all the information that has been presented by you and others here. I think that there are only 2 wires (2 - #15) on the center coil and he thinks that there are 4 wires (2 - #15 and 2 - #18). Then of course there is the whole thing about half the impedance.

Any interest in proving one of us wrong?

Thanks again for your help last night!


Brent

PS Eager to see our 6' wheel begin to spin!!! "Junior" as we like to call it!
