Power ratio over one

Hay Gyula:

Funny that you mention audio type circuits. My research does point me in that direction. It does appear that I need to get the frequency up. I have a few friends that are into the audio type stuff. I will have to grab a six-pack and go visiting!

I have been reviewing Newman?s machine. He is quite the character! I have been spinning the magnets in my device and it does create ?bad? forces. That makes me wonder about Newman spinning his device. Maybe the slow spin on a device the size of his overcomes that problem (hysteresis). I will also have to try out Gary?s idea.

Thanks for the links. I'll update as soon as I have something.

Hi David, what kind of "bad forces" do you get, when you spin your rotor and leave the drive coil open circuit ?
What then about the drag onto the output coils, when you leave the LEDs connected ?

Hay Stefan:

The bad forces I am referring to as far as I can tell is hysteresis. With no load there is no slow down of the device, when I spin the magnets. Using the LEDs as the load and spinning the magnets very slow, I don?t notice any slowdown, or opposing force. The faster I spin the magnets the more resistance I can feel.

I used a 3-volt motor first to spin the axle, then I used my fingers. The resistance is obvious. During my initial experiments, I noticed the same thing. That finding led me to find another way besides spinning the magnets. That?s how I came up with the quarter turn each way from the magnet edges vertical orientation.

This finding makes me wonder about the magnets spinning in the Newman machine. I believe the reason Mr. Newman only does mechanical work with his device, and does not hook it to its self is because the motor, in conjunction with the powerful magnets has a high level of torque. This is why he runs his machine at such slow speeds. I noticed that when my device is running I can pinch the axle and there is plenty of torque and not much slowdown. However, if I add just a little bit of electrical resistance it has a big negative effect.

If this doesn?t answer your question I will try again!

Hi David,
I now see what you mean.

I guess it comes from the effect, that the LEDs just have
a threshold voltage before they conduct the current.

If you are below this threshold voltage level ( as you have several diodes in series)
your resistance of the series LEDs might be very high, maybe a few 100 KOhms.

Now if you turn your rotator faster with a motor you will
get over the threshold voltage of the series LEDs and then the
load resistance of this series LEDs will be only maybe 200 Ohms,
so now you have a low resistance with amp drawing, so it is dragging
your rotor and will slow it down.

I would recommend you should first try to do a rectification with a greatz bridge
rectifier and a big cap directly at the green output coil and see, what voltage you will
get before powering the LEDs.
This way you will have a DC voltage you can power your LED chain.
Then see, if this will slow down the rotor again
and this way you can also see what energy you can get out of the green generator
coils, when you choose a bigger electrolyte cap, like 2000 uF or bigger...

You should first try this experiment before you try to loop
back so you will see, what DC voltage you will get at all at an output cap.

Many thanks.

Regards Stefan.

Hi David,
just use first such enclosed picture circuit and measure the DC voltage at the output
and then use one LED chain to power it and compare
with your old setup.
Many thanks.

Regards, Stefan.
