Dear All.

Resonant single field coil.

Cheers Grum.
Thanks Grum, I'll be calculating my cap this morn. I have to drag the macbook out to the lab and stick the scope on it. Only one channel working on it now.

Diode.
Whilst i get a 200ma drop in current draw i cant seem light a lamp at all. interesting


EDIT: Ignore that - turns out im a bit of a dickhead. lamp lit

Just blew the other channel of my scope. Realise it had a max input of 35v and the stator coils were putting out 36v doh

Hi everyone,

nice job on the resonance Grum!...  I'm glad TK is still testing. Thanks for sharing guys,

No sleep yet at  4:15am.  My fist test video of the RT is just about done. I think you guys are going to like it. I had the ideal a few weeks back and been wanting to test it.

Hi all, Excellent videos' .
Luc, does that diode prevent supply voltage from getting to your field coil?
It looks like TK is feeding 1 field coil from the other,but preventing the 2nd from being fed by the first.
I will try different diode arrangements.
Thanks artv

I am sure you remember that most on the other forum chased this rabbit.  Specifically they were pulsing both modified and unmodified brushed motors using PWM circuits.  In either case, in some instances, very interesting results were accomplished, some of which I was able too produce myself.  The addition of the PWM is facilitating high frequency "gating" of the low frequency produced by commutator action. You feeding it back into one of the field windings shows me that it is difficult to break away from tested concepts in the past.....in watching your demonstration, I am reminded of a demonstration you preformed a few years back where you took the flyback from a coil being pulsed and redirected it back into the coil where the flyback was being produced.   I am curious how many appreciate what you suggest at the end of the presentation...


Regards
The coil shorting you mean? Oh yeah.
Thanks Luc. Great build. Be interesting to see what a higher freq commutator would do.
I did mine in series today with a lamp in series uses 200ma less current than my previous build in parallel. However the lamp did not shine as brightly. Shorting the coils though spun just as fast with the lamp in series.


Also tried an LC circuit. Worked out I need a 0.54 mf cap but all I had was a 0.68 . Lamp shone brighter no change in current draw.

Gotoluc clearly states that he's directing flyback from the "Rotor Coil" into the "Stator Coil".

I didn't call into question what Luc is doing.....I know what he is doing because he specifies what he is doing.....  What I did was relate what he just presented with what he was demonstrating in the past.....research.

There was a guy with sandwiched window coils who got keen "Lenz Propulsion" redirecting flyback to the power coil that way.

I'm sorry I was referring to what luc was doing at the end and you wondered how many had understood what he was doing. Were you referring to the acceleration on the shorting. Were you referring to the high impedance coil discussions? The difference now being that the stators are low impedance.


Edit. Sorry I just saw your last post. Thank you.

Interesting circuit for the fly back but didn't think much of his measurements
In the first half of the vid. Anyway, I must admit I lost interest.

This "Flyyback" video explains what's taking place:

https://www.youtube.com/watch?v=QRyKVU6YzYw

Directing the large flyback spike back into the power coil does not increase acceleration and reduce ouput by adding power. The spike produces a "Hysterysis Loop" and causes "Lenz Reversal".

The generator coil is sending A.C. output through the diode bridge to a capacitor for a fixed time frame, from both sides of the spike. The spike is merely nested inside the enveloping charge.

The power coil cycle includes a rotor related magnetic wave event, that is reflected at a retarded pace, causing "Lenz Reversal".

Hi everyone,

thanks for your feedback!... pun intended

So apparently UFO politics used a PWM in his experiments. I didn't know since I only looked at his topic at the beginning and lost interest then.

Using a pwm was a quick and easy way to see what the effect of sending some of the outrageous current (2.4A) the rotor coil consumes back through flyback to the motors stator coil and load. The effect was a positive, so I shared it.

My original idea was and I still may do it, was to modify the brushes by having two sets of brushes. The second set would be a little advanced (from the first set) and would have a diode so when the first set of brushes comes off the commutator segment the rotor coils flyback would be collected by the second set of brushes and reused. That's what I wanted to do. However, it's a more complicated build and a few days ago I thought of using a pwm to chop the DC input and collecting the flyback multiple times while the brushes are still on the segment. This allowed to test the effect before hand to see if it's a worthwhile effect to pursue. I not trying to take someone else idea or work and claim it as mine. I'm only interested in results, not fame and fortune.

None of the pwm input goes through the stator coil diode. What you are seeing in the video is only rotor flyback going to the stator coil.
