Reviewing Pulse Motor Circuit Ideas and Theory

[darediamond]

I am addressing the last three posters: Brad, dieter and darediamond collectively, ie, in the same post, as there are topics of interest in each which tend to have some overlap and bear on this subject.

Brad's quote

Tesla mentioned this apparently in his speech on The Magnifying Transmitter:
"The truth is this: In the air the potential increases at the rate of about fifty volts per foot of elevation, owing to which there may be a difference of pressure amounting to twenty, or even forty thousand volts between the upper and lower ends of the antenna. The masses of the charged atmosphere are constantly in motion and give up electricity to the conductor, not continuously, but rather disruptively, this producing a grinding noise in a sensitive telephonic receiver. The higher the terminal and the greater the space encompassed by the wires, the more pronounced is the effect, but it must be understood that it is purely local and has little to do with the real trouble."

I thought about the concept of movement of a permanent magnet through or past a wire wound coil and my question was "How far does the magnet have to travel to induce any current or voltage?" I say that because I was thinking, can the magnet travel a very small distance because of some resonance or frequency established in the magnet itself and thus satisfy the requirement? This would be something like I envision a crystal oscillator to be. Some small electric voltage is applied to this crystalline material and it vibrates at a given frequency. Why not a permanent magnet likewise?


dieter quote:
Perfect for the air core coil experiments with a high frequency pulse. Or see below after darediamond in my response

Now the question becomes how complicated of a circuit is needed to achieve these pulsations?

Should a Tesla coil be part of the answer? The reason I ask this is because so many of the videos and instructibles I have watched concerning the Tesla coils, especially the SSTCs describe problems with mosfet overheating, proper resonance related to the correct number of primary turns and secondary turns. How long is the coil and how wide? Seems like endless possibilities. Also too, I am not trying to produce any sparking or displays of such a nature as we usually associate with the Tesla coils.

On TinselKoalas video
https://www.youtube.com/watch?v=XMQkCW5vZVc
he talks about the CD4046BE Phase Locked Loop (PLL) which contains its own Voltage Controlled Oscillator (VCO). This could be good for a setup like this even without trying to cause sparks or corona, or as seen below maybe with a carbonyl iron material.



darediamond quote:

Why isn't the standard magnet wire enough insulation in this case?
I have seen that there is a Carbonyl iron material that is used in high frequency applications so this might be preferable to a pure air coil for magnetic field generation and energy harvesting even at high frequencies if they work as good as that.

While on Ebay I see that some people were selling these carbonyl iron toroidal cores. I would consider stacking them and glueing with epoxy to keep them aligned if anyoine thinks this could be a reasonable substitute. I did that on a similar setup I was working on with a Joule thief circuit designed by lasersaber.

I would even consider buying them and crushing them to powder and reglueing them in some way to make a custom core if that would work.

Anyway, lots to think about, discuss, and create some experiments. Some of you all who actually may have a Tesla coil in the closet can help, especially if you have an oscilloscope setup to take readings for us.

thanks everyone for sharing ideas. I'd love to see some things gel.

The coating on the magnet wire is not whatbis needed to separate each layers of Spirally would did this time. You need plastic tape or any other dielectric material to separate each layers of spirally wound plate to get the effect I am talking about.
I think you know how normal capacitors are made.
You can also mimic the process when winding g your ele tromagnet to get the best result.

Wish I am able to  explain this via video but can not do that now.

But I want to reassure you that THERE IS REALL FREE ELECTRICITY IN THE AIR WHICH CAN BE HARVESTED TO POWER JUST ABOUT ANYTHING THAT NEEDS ELE TRICAL POWER TO WORK

Now as for sparks that is always generated when  pulsing DC is applied to an electromagnet,  just connect the 2 leads of your Electromagnet in parallel with leads of the high voltage AC Capacitor. You can use the normal CBB capacitor of 475J which is 400V 3.5uf or so.

Simply connect in series the amount that will make ii ten fold the amount of voltage you send to your Electromagnet

hello ltseung888,

I looked at several of these videos via the link provided which in turn linked to others. As noted by one of the  viewers, manual control of the pulse is poor at best and humans don't focus that well on the timing, but the automatically sensed trigger of at least a bifilar coil arrangement as Bedini included in his designs is good, or using a hall effect sensor arrangement. I didn't really understand what the point was in the videos you supplied, which seemed to be going over old ground. Maybe I missed something.

The point is to determine what are good pulses and bad pulses.

I would regard those pulses with large negative voltage and positive current at both leading and trailing edges as good pulses. 

The manual action is to capture and examine one pulse to see its characteristics.

So far, we have found the exact timing and the duration of the pulse are important factors.  Different people or different attempts produced vastly different pulses.  Most of them are bad.

It is likely that automatic pulse motors may produce some good pulses and some bad ones.  The Tong Wheel was such an example.  I am sure that many poorly hand built Bedini wheels are in same position.

Thus I advocate the examination of the pulse waveforms is vital in the research.   

*** The good pulses lead-out energy.  The bad ones are like pushing the swing at the wrong time.  They generate heat and waste energy.  A mixture of good and bad pulses in the system is bad.

*** From the waveforms, the sharp high negative voltage has duration of less than 2ms.  Can all the "properly" constructed pulse motors do that?

Ok, focusing on the dielectric winding first. I see that mylar film will fulfill this obligation with a dielectric constant of 3.1 while teflon is 2.1, but is much more expensive.
I have plenty of 20gg magnet wire just to experiment with. I would like to try this out first since I feel it would be a relatively inexpensive trial.

I saw these on Ebay today:

So far I am only working on 12v dc from a 12v 18AH rechargeable, not even AC at this point. Again I am not looking at spark production, only energy harvesting.

can't believe I missed your post. sorry about that.

I think most would agree that the waveform analysis with a scope would be ideal for perfecting the rotational moment for the correct timing of the firing of the pulse in those cases.

I am not looking at rotational motion myself, but nevertheless, feel that the appropriate resonance in my circuit would be advantageous, like the suggestions by TinselKoala for PLL and VCO control.
I am focusing more on high frequency circuits and coils. At this juncture, I am trying to read up on the CD4046 PLL/VCO chip, PLLs in general as I see that as a path I need to investigate more fully.
Also, I want to study more on the electrical rationale for the way in which a SSTC is built, and what changes cause other changes to occur.

I did download and print the circuit by uzzor from his website as a study guide. I don't understand the rationale for the 555 timer circuit as the Interrupter though. There are several Class E circuits here.:
