Lenz Delay Experiments

[SkyWatcher]

Hi all, thought i would make my own thread, so as not to clutter up bromikey's thread, besides, my results were being ignored there anyway.
So i have made some tests and have found that a ferrite tube, inserted into a coil, with the ferrite tube protruding from the coil on one side a certain length.
In this case, it's protruding about the same length that is within the coil.
The coil in the video 2 test, is 24awg. magnet wire, with 5 strands wired in parallel.
Parallel resistance is .8 ohms.
Using a dc brushless RC airplane motor to drive the neo magnet rotor, it is NSNS.
Video 2, shows that the rotor is slowed down with just the air coil placed at rotor magnets.
When the protruding ferrite tube is used, the rpm under coil short, is not affected.
Here is my idea of why that is.
It takes a certain amount of time for a magnetic field to develop within the protruding ferrite tube section.
It also takes a certain amount of time for a magnetic field to build within the coil.
It also takes a certain amount of time, for that induced magnetic field within the coil, to propagate back to the rotor magnet.
The rotor magnet still needs a certain speed, for it to pass each phase of approaching and departing from the coil/core.
This is why it does not slow down the rotor.
Your thoughts are welcome.

Great thread SKY i email you questions on youtube and
I got no answers. The sound does not work. Splitting the positive
thread is open to all who want to post their results but be prepared
to answer questions.

Your experiment is something LUC did also sliding the coil up and down
the rod core material to give a 90 degree lag. However due to not
following proper coil designs nothing much happens. Ignoring procedure
to get the right results by using random coils or random reinvented
wheels leave everyone else except you out of the loop.

This is why your experiment made no sense over in that other thread.

Now this thread it will make sense.

Are you going to answer my question? Did it speed up? The sound is broken.

peace, love, light and joy and all that good stuff SKY talk to us.

Hi mike, thanks for replying, sorry i didn't notice your reply earlier at the tube.
The rotor does not slow down or speed up, the noise difference heard, is the chatter created by the core, though when i quickly remove the core/coil, the sound can be heard to be the same tone.
I also used an amp meter before making that video to confirm the amperage did not increase.
I need to get a photo tach from harbor freight or something, to show on videos.

I should also add, further tests need to be made.
Like increasing rpm's, that could cause the rotor to speed up under load, though with this current setup, i would want to put a shield between me and the rotor and mount the coil/core.

"i would want to put a shield between me and the rotor"

And that is no joke Sky

Had to get that laugh in there. I have frames coming I will show they
go on each side and top JUST LIKE Thane does it for showboating my
rig but more than that so I don't get my head blown off.

It is a really strange feeling you get running good rpm's under vibration
as you realize it could crack, chip, slip out and go at you at any second.

Now for the other part of your post. First you need more coil mass,
second your ferrite rod could be a 900 or 1200 or a 300 nobody knows
do they? Or did you say and I missed that?

Maybe someone with more experience could explain the chattering,
guessing so many things is hard. However when you get a large enough
coil and you reach a point when putting the coil close to the rotor
magnets does not slow down, then you may be getting where the
delay is taking place.

Good experimenting. From what I just recently learned maybe you could
tune your coil with a capacitor to improve your result. Maybe the chattering
is the rod slapping back and forth in the coil opening? Maybe tighten
up the fit? Guessing.

Or another guess could be that you are bordering on the delay and it stops
for a mili-second then delays again? Just guessing I am as new at this as
you are.

The faster you go the smaller the coil might be if you tune with a cap
but we are talking 4000 rpm's. This is why I am using the large coil set.

High rpm's require precision machine work and slow speeds need more coil
mass to get high COP. There is no free ride, you know it now.

You want to work at random builds, be my quest, I've done that also and
now I am thru playing. Time to build a coil that can give success every
single time on any rig.

Slight speeding up under load is cute at first but unless you can collect
some decent power from the coil during this event it is nearly worthless
in the practical sense.

In other words you will conclude that it does not work as so many are
doing.

Hi all, finished the coil/core today, will be testing it tomorrow sometime.
The coil is 30 awg. magnet wire, single strand.
The coil itself is around 1.4 pounds.
Resistance is 470 ohms and 4,557 feet long.
Ferrite tube is used as core.

Hi all, i tested the large coil today.
I placed the ferrite tube core as close as i could get it by hand, without being unsafe and it did NOT slow down at all when shorted.
At the rotor speed it was at, the open circuit voltage was 175 vac.
At the slowest speed i can get the rotor to go, it did slow down slightly with coil shorted.
Then one more notch up in speed on my RC transmitter, caused the rotor to be neutral upon coil short, meaning it did not slow down.
Though without a tachometer device, i cannot tell if it speeds up a little.
Here is a pic of the setup and a video.

Good thinking Sky, always be careful, I am ashamed to say I took some
chances yesterday walking around my spinning rotor without shields.

Another thing I thought of about you and I using the thread like wire, you
30 awg and me 29 awg was that it seems to have little effect on the
rotor either way which is good for starting out. If I load this coil at the
wrong speed and wire length it slows right down and from 400 feet all the
way up to 2400 feet the slow down is pronounced. For this rig.

AT the 18,19, 20 strands or 3400 feet their is very little or no effects
however it is the turning point for me known to many as the "Break Even"
spot. Now I need to keep going another 3 strands (3 X 175 = 525') TO SEE
if going more feet away from this TDC or "TOP DEAD CENTER" point will
increase acceleration greatly. I think I am just over the top and with a new
motor running 2000 rpm's plus I will be way past that break even.

Hi mikey, thanks for sharing the information.
Definitely a few variables involved with this.
I tried a 120 volt led bulb load, non-modified, directly across the coil.
The 6 watt led bulb lighted to maybe half brightness and did slow the rotor slightly.
The amp draw of the motor increased by about 10 milliamps.
I read that turion was experiencing similar things with real loads.
Will have to think about this and read what turion shared closer.

Hi all, i decided to switch tracks a little.
I'm testing a somewhat smaller sized coil, though it has painted coat hanger wire as core, from previous bedini wheel i built.
The coil is 7 strands of 24 awg. magnet wire and they are in series.
Also, the core is set back a little in the plastic coil former.
I am not observing much core drag at all and at a certain speed, when the coil is shorted, i detect no slow down in rotor rpm.
I will test loading the coil with a practical load sometime today, like a 12 volt battery.
peace love light

Edit: I tested the coil/core and did have a little slowdown when the load is a 12 volt battery.
I have other 7 strand coils, so am splicing them into this coil.
Each coil strand is now 3 ohms or 117 feet, though i have another 7 strand coil if i need to splice in more length to test.
I will test this coil first, then add more to test.
