Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

For Synchro

I think what is confusing you about the current not reversing after the reed opens is you are not realizing the coil becomes the source of current and not a load.

You can easily prove this to yourself if you have a 2 channel scope.  Simply add a low value resistor like 1 ohm or so to the circuit Tinman has provided in series with only the coil.  Now watch the scope channels as you turn the coil on and off.  You will see the signal across the resistor only goes up as the coil is charged and discharged.  But the channel across the coil will show a reversal of polarity.  But obviously if the channel across the resistor doesn't change polarity then the current does NOT reverse.

If we use the old school idea of electron flow you can look at it this way.  The negative terminal of the battery has a surplus of electrons since electrons are negatively charged.  So when the reed switch is turned on electrons move from the negative of the battery into the bottom of the coil.  And electrons flow out the top of the coil back to the battery.  If we put a meter on the coil we see the top as positive and the bottom as negative because the excess of electrons is at the bottom of the coil.

Now when we turn off the reed switch the collapsing magnetic field wants to keep the electrons flowing in the same direction.  Since the coil is now the source and the current is still flowing in the SAME direction as before we now see the top of the coil as being more negative than the bottom.  The current has not changed direction but the polarity of the voltage has changed.

Power measurements continued...

For the LC circuit by looking at Laurent's waveforms we can see that essentially all of the drive coil's pulse energy first goes into charging the one-uF capacitor.  This is what was expected because the secondary coil will be blocking the initial current flow from the pulse of current from the drive coil.

So, we have initial maximum voltage measurement across the capacitor .  From that we can calculate the pulse energy that goes into the capacitor [J].  If Laurent has a capacitance meter it should be used to get a more accurate value of this capacitor.

Now, we know the "exported pulse energy from the drive coil" [H], and we know the maximum energy that is transferred into the one-uF capacitor [J].   Therefore we can make a reasonable inference for how much pulse energy gets imparted onto the rotor from the drive coil [K], which is ([H]-[J]).

Here is where we are:

A - Average input current for entire circuit
B - RMS current through the drive coil
C - Power dissipation in the resistance of the drive coil
D - Average input power
E - Exported power from the drive coil, ([D] - [C])
F - Pulse frequency
G - Input pulse energy ([D]/[F])
H - Exported pulse energy from the drive coil ([E]/[F])
I - Maximum voltage across the 1 uF capacitor
J - Maximum energy in the 1 uF capacitor
K - Main drive coil pulse energy that is imparted onto the rotor ([H]-[J])

Thinking a bit more, and on topic....

I reposted Woopys circuit for reference below.

If you see the red x labeled 4, if you put a diode there, same direction as the one to the left of the x, the cap will discharge all of its charge through the coil only once.

Now for possibly an even better effect. Havnt tried but I think it would be a good thing if it works....

When the cap charges, then discharges through the coil with the added diode, the cap will fully discharge, and then some due to the flywheel effect of the coil, meaning the cap will end up with a charge reverse of what it started with. The possible advantage is, when the next spike comes from the primary drive coil, it will be facing a cap with a charge that is well willing to accept the spike as the polarities will be in series. So the spike enters the cap with help of the charge already in the cap. The possibility is that the cap may charge higher than without that added diode. Im pretty sure of it from my experience in this stuff.

Thinking more, again.  I need to try what I just wrote in my last post. There might be something really good there. possibly more than I imagined.

If the cap does get an increased voltage level, the next pass may get even bigger and so on. Just went through it in my head. It just might be so.

this post was gone, I checked from two computers and 2 different browsers, now it's back...    http://overunity.com/16167/sharing-ideas-on-how-to-make-a-more-efficent-motor-using-flyback-moderated/msg466152/#msg466152
My mistake.

Yes, your mistake as it's impossible for me to delete a post and then re-post it using your user name.
That's the second time you accuse me of something that is not true. So please chill out and stop jumping to conclusions.

you answered indirectly when you replied to MoRo's attempt to reply to my question:

"The next thing I would recommend is a device that needs a long flux holding time. This is why I recommend a PM flux switch.[/size] [/size]I have already designed and built it. I'll call it the GTL (short for "go to luc") Gate. The GTL Gate uses the same design principle of my mostly magnet motor, where both inner and outer fields of the coil is used which gives you double the magnetic field and obviously double the core surface area."[/size]
I still do not understand it though.

You didn't add the part I wrote saying if you don't understand you will once I demonstrate the GTL Gate.

You know me from past. I've often commented in your vids. I've always had good things to say about your work.  https://www.youtube.com/channel/UCrIHB1lv7XElAD_ztL-1FPw

So you're cool Joule

You might not appreciate my tone, but I did not appreciate the smack when all I did was share my opinion in the first post about JB.

My first post has this warning: "If you wish to post in this topic please keep it on topic and constructive as I reserve the right to edit or delete any post that are not so"

So how can this be a shock when you post about J Bedini stuff and then more posts arguing with others that it's the same thing?... I think you're over-dramatic.  And right now me taking the time to write this is taking away from experiments and also adding pages with useless posts. Do you not see this?

I hope I'm understanding this correctly, it is not discharging into a cap that is in parallel to a coil that will aid in spinning a rotor (to put it simply) that you are interested in; however, your interest is in creating a fluxgate using only high voltage/impedance coils that will hold/pull with more force using the spike? This GTL sounds very interesting. I have lot's of ideas how to use the spike to provide more torque, I cannot think of any that would aid in a mostly magnet motor - very interesting indeed.

Yes correct, my experiment results lead me to believe a flux gate would be best use of this effect but that doesn't mean there is no other use for it.

The mostly magnet motor was a good learning experiment. It has taught me many things that will be incorporated in the GTL Gate.
I see no reasons you have not started experiments as we I can see you have plenty of stuff to use and make a video of your findings.

Looking forward to seeing ways you can think of using this and your experimenl results
