Beauty and truth united in dance, enkindling hope and joy perchance. Can't help it. That was beautifully done, UFO - brought out the poet in me. Warm regards, Bob |

I watched the video. This is a tremendous in sight for us working these motor-gen units. The animations were the best I have seen.
Getting the rotor and magnetic feild moving in the same direction is one of the things we have to do. Thanks again for sharing your knowledge. Sharing is RECEIVING. In that I mean as we give freely what GOD has given us, He will continue the flow of knowledge, In what we are pursuing. Great time to be living in. |

Hi UFO
I'm getting there... going very slow... life keeps getting in the way. I did get my fets though. I ordered an adjustable DC to DC converter for cheaper than the LM317 costs In fact I bought 10 of them, because I can see several projects I can use them for. 10PCS,LM2596 DC-DC adjustable power step-down module NEW | eBay Till they come in (in July ), I will use a wall transformer for my 12V. I am getting ready to build the coil, but I need to ask a question first. In your introductory to the "My motor got me to ...." thread you said that a hollow core coil would be better than a solid core and said you would explain later, but then I have seen discussions about different cores... should I build a hollow core coil or what should I use? After all I have read I still don't know what the volts and frequency we should expect out of the primary coil. Of course that will be the BEMF so it might be hard to get an exact figure. I have to keep thanking you for your generous disclosures. You my not know, but you are helping me at so many levels. Can't wait to see how all this ties together I only know how I think they do. Regards Larry |

Hey Larry..

The lm317 is pretty cheap at Radio Shack...maybe 3.00 USD... A hollow core would work great, bifilar winding , meaning double strands 18 awg wire, attached in parallel...the more strands the better Larry...so if want to go Quad filar...better. Go 200 to 300 turns on a 2 Inch core. It works also with steel core...(Ferromagnetic Resonance), but the steel will end up magnetizing one way, if it is not treated...so what happens is after a while of use it takes more frequency levels on our side to climb up Radiant... You should expect milli amps of Input and Hundreds of volts at output Larry...The Input Frequency could be from 100 to 800 Hz...Output 1500 to 2500 Hz... But again, the capability of your oscillator to reach clean, fine signals is the key to obtain better results... By the way, I do not like transformers in this set-up...they induce flux Noise into the signal circuit...even if you rectify them with top of the line diodes (ac/dc bridge)...still leak.

Voltage Regualtors
Is there no cheaper source than Radio Shack?
In Europe we get a LM317 for €1.20 while radio shack sells it for $2.99 / Digikey $0.80 A possible alternative could be LM7812 fixed 12V regulator (Europe €0.65, Radio Shack 1.99 / Digikey $0.70 ) Limits: - LM7812 input recommended below 36V (good for 2 lead batteries) / 1 Amp max. with cooling (only 2 additional caps needed) A resistor in series at input allows higher voltages. - LM317 input recommended below 50V (good for 3 lead batteries) / 1.4 Amps max. with cooling |

Lm317
Quote:
Hello John Stone, Yes Digikey is the cheapest place...the only thing, I really do not like to wait for days on a part I know could buy it off RS...or NTE... Now, there is a superior one to the LM317, that allows 3Amps...not sure which one is but it is within the LM3 numbers...and it is not the LM337 Negative V Reg...that goes same 1.4 A... The thing I really love about this LM317 is that they ever go bad!!...they reset after a crash...and as long as you keep them cool they perform excellent...Mines live in a "Royal Suite"...Brush-less Fans...Super-duty Heat Sinks...and lots of "extra room"...lol However, we only need one of this things per circuit...not like Mosfet's though...where the more we parallel the more robust the switching power is...

+I have a couple of spools (pictured below) with a 2.5" core and 4.5" outer I had the spools made with a 3D machine at the college where I taught electronics for a while. BTW they are mounted on a solenoid motor I build from scratch I did the engine on a CNC mill I designed all parts and did the CAD work and ran the machine. The spools have 100 turns of 18 or 20awg (I can't remember maybe 16AWG) wound Quad filar each. Quad filar is hard to wind and I am not sure I would wind again if it were multi-layers.

That would be the LM350, but be careful and check the power dissipation it doesn't necessarily mean 3 amps at the max rated voltage. Heat sink and fan will raise the out put Amps.

Asymmetry
Quote:
Thanks for clarifying in what context Asymmetry can be used. I was only approaching this from a single perspective of inbalances. More research is needed to ascertain the total scope of how asymmetry interacts with Electrodynamic machines and their relationship to the variables (My quote) I see this Asymmetrical motor concept just as Tesla desribes (patent 524,426) with the inbalance in the length of the pole pieces cause a magnetic phase difference. Each set of coil pairs will exhibit a time delay in proportion to the core of the coils length and thus create an inbalance of magnetic flux to each coil pair. (End) Nope...You got it "kind" of wrong there... Asymmetry DOES NOT refers to the structural, nor the disposition of coils, Nor the length ...BUT, to The Way they Interact between each others. Not by "Unbalance" either, my friend...they could be perfectly balanced, and as a matter of fact, an unbalanced electrodynamic machine will never run "even"...or "balanced"... Asymmetry refers to an Asymmetrical Interaction, where Pairs or Groups of Coils are NOT aligned TO INTERACT in a "Symmetrical Array"...Capische? Symmetrical Interactions mean to "Self Cancelling Magnetic Fields" in a "Symmetrical Fashion"...like Tom Bearden writes...Killing the Dipole in every turn. Now whenever you leave that Coil or Dipole free, idling for a few seconds...then you broke the Symmetry... I hope you understood now... Regards my friend Ufopolitics >>> There is an abundant amount of variables that I could implement as to what context the asymmetrical systems will be achieved in your Tesla inspired designs. Time will tell. Looking forward to the "Asymmetrical Motor" clip my friend P.S - I do not mind that my analogy was not 100% accurate. I"m happy to be incorrect if someone can show me the error of my ways and engineer real world experiments to prove their conclusions. As you have my friend with real builds and not just calculations. (since Radiant has NONE) Regards Zero |

I have to interject here as I had read you state this before. Putting the fets in parallel only increases the amount of current they will handle, but doesn't increase the voltage they can handle. In order to increase the voltage they could handle you would need to series them and that would present it's own set of problems to this circuit. Tell me what I am missing.

The 3 Amps are good for instant high current surges. But please take in account that a TO220 case will enable less than 2 Watt heat dissipation without additional cooling - independent of the semiconductor contained therein (LM340, LM350, LM317, LM7812). Example: LM317 Thermal resistance chip to case = 4 Kelvin / Watt Thermal resistance case to ambient = 50 Kelvin / Watt Total: 54 Kelvin / Watt Ambient = 25 °C (enclosed in a case will rise i.e. up to 45 °C) Total chip temperature: 150°C Differential: 125 °C Calculation: Free air: 125 °C / 54 °C per Watt = 2.3 Watt as absolut maximum In a case: 105 °C / 54 °C per Watt = 1.9 Watt as absolut maximum This chip does not die if temperature exeeded but will reduce current and thus stop its function as regualtor.

Finally I found the circuit schematic I lost many years ago. It is a kind of jewels we should always have !
12 Volt 30 Amp Power Supply a way to construct stabilized large amperage power supply using limited output current IC. I bet the same could be done using lm317. Hope that helps. |

Yes I know Larry...

Yes I know Fet's in Parallel will increase Amps...that is what I meant by "robust"... Sorry about my Non Patient "Statements" written above...Larry!!... The Fet's I use (NTE2397) are rated 400Volts...I still, have blown many...but, because of my errors... Regards Ufopolitics |

EFTV # 5 + 13: Electrodynamics
Quote:
Between experiments I have managed to watch EFTV # 5: Hidden Electrodynamics and is an older Bearden with a more simple/expanded theory. I had seen it when I recieved my DVD in May 2011 but for some reason had not come back to watch it again, till last night. Thanks for the re-inpiration my friend. Also, EFTV # 13: Electrodynamics, It's Origins, History and Struggles was the newest DVD he made describing this issue. Regards Zero |
