Is this the first selfrunning overunity motor w/o batteries ? Mike?s motor

Hi,
Gustav Pese just emailed me this link.
This is pretty interesting reading, if one
is switching coils:

Normally with coils you have Voltage_induction = L x di/dt
Now if you also change L over time it must be something like:

Voltage_induction =  d ( L(t) x i(t) ) / dt
which has a much different solution, where more energy important terms
come up.

IMO Pese's link to 'Inductive Kick' is getting to the heart of what is going on in the WM and other energiser devices. Nothing magic just understanding what inductors and caps do in different configurations by transferring energy back and forth. What we can be sure of is that this process is not perpetual. Thanks for posting this Pese. Although I am aware of the theory, I had not seen this particular document.

I just cant help notice the similarity between this Bedini-Cole motor and the PM (permanent magnet) stepper motor. The PM stepper motor has similar rotor (N-S-N-S-...) magnet arrangement, but different stator winding.
If you used a bipolar PM stepper motor before, you'll probably notice the similarity (not exactly the same) of the transistor driver circitry (H-bridge) that can also achieve total isolation of the coil and also the bridge diode configuration for the back emf handling.

some years back I used the PM stepper motor for some industrial applications and I remembered I had a lot of problems with the "unwanted" spikes here and there. Normally the standard driver circuit just "short out" the spikes to the supply lines. But I remember once I did use part of the back emf (using zener diode), not completely "throwing" it away, and it did manage to DECREASE the power requirement for the motor. I was quite amazed since only a few old technical notes mentioned of this zener diode usage, while the majority of technical notes available just simply told me to short out the back emf, what a waste of energy !

Well, the main difference with the Bedini-Cole setup is that I didn't use ANY capacitor for the back emf reservoir, and unlike this Bedini-Cole motor, I didn't use any timing circuitry for back emf feedback. As soon as the driving pulse stops, the back emf is captured, or should I say "not thrown away".

Maybe if I used some sort of timing circuitry for the back emf feedback, I might get a sharper and higher back emf spike. And if I used a capacitor it might be more beneficial for the whole setup.

Well, I'm not saying a PM stepper motor can operate as a self runner, since there are also a lot of differences between the 2 motors. But I am saying that from my personal experience the use of back emf (feedback) has a significant effect on the reduction of power usage.

Considering that most EE studies nowadays is to minimize and eliminate the spikes and other "switching" noises, I believe we know very little of their potential if we were to use them instead. if we were to MAXIMIZE them, I believe the idea of a self runner is not so far fetched. I hope so...

Hi All,
I just did this test with my Newman coil and a stack of a few 9 Volts NiMH batteries and a graetz bridge
from 1N4007 and 2 different capacitors !

Wow, I can just charge up  the 0.22 uF cap in a few seconds and only with a few open and closing
of sw1 to about a few hundred volts in about 3 seconds and
the same goes , if I replace this cap instead with a 15.000 uF 30 Volts type
I had lying around, I can get this cap to charge up to 15 Volts and even higher in 3 seconds
by just tapping sw1 a few times and giving the rotor a slow push inside ths coil !

When I short out then the 15 Volts charged up 15.000 uF cap , it gives me a real good spark
at the connections !

This is amazing, how fast these caps charge up.

Okay, my opencircuit voltage from the coil is around 800 to 1000 Volts  peak to peak from this about 16,9 kOhm
DC resistance coil with about 4,65 Kg of copper wire.

I have now still all 3 partitial coils of my Newman coil in series as it was before.
Now I will use the charged up cap to pulse this charge into a partial coil of this Newman coil.

Let?s see how this works....
Have to repair first the commutator of this machine
for snyced operation though...
Stay tuned for more !

Regards, Stefan.
P.S: See attached circuit diagramm. Sorry for the sloppy drawing, but I rather
make experiments than to draw longer time in a circuit design program...
But at least I am doing circuit diagrams at all ! Do you hear this Dave ?
