Thane, one question.

Does your motor speed up faster, or is the effect more pronounced, if you place your external solenoids, on the same side with the motor?  (relative to the wheel)    I would venture to guess yes, since the flux linkage is greater through the motor axle due to the proximity.

THE SHORTER THE FLUX PATH THE BETTER THE EFFECT.

What would be really great is if this phenomena somehow had to do with mysterious torques occurring on the magnets themselves.  That's what I was thinking initially when I saw the videos, sort of like the Adam's motor and others.

YOU MAY HAVE SOMETHING THERE - WE ARE LOOKING INTO THAT AS WELL.

 I don't know if you meant that genuinly or not, but either way 'yes'.

But it would probably cost more to get it to NZ than it would cost for me to just build, so I'll take a shot but if it fails I might be seriously interested in taking you up on that offer genuine or not since I think you have something here and I really want to explore it.[/quote]

ACTUALLY WE HAVE A COMPANY IN THE U.S. WHO IS CONSIDERING BUILDING SMALL UNITS JUST FOR PEOPLE WHO WANT ONE BUT DON'T WANT TO BUILD THEM THEMSELVES - LIKE THE STERLING ENGINES.

PAY ATTENTION TO THE VIDEOS AND YOU CAN'T FAIL. JUST TAKE ADVANTAGE OF YOUR ROTORS LEVER ARM TO INCREASE TORQUE - DON'T MAKE IT TOO SMALL.

@PulsedPower,

Magnet wire cost approx. 280,- NOK/Kg bought in Norway. (Approx. $53 pr. Kilogram.)
So unwinding is also a slow process because I reuse the wire. Using a grinder will destroy
the magnet wire and also the core if not careful. But it is a fast way to unwind a core.

@pese,

There is also a brush less induction motor where there is two shorted coils on the Iron laminate.
This motor has two stator coils on the laminate and two one turn shorted coils at 2'o clock and 8'o
clock as seen above looking at the coils pointing at 12'o clock position. The rotor is a laminated soft Iron
round rotor. These motors is used in computer fans (of bigger size) where you want to drive the fans from
the AC mains. Such a fan will use approx. 8 - 9 Watt/Hour from the mains.

I use those fan motors for various projects. One way to use them is to remove the outer fan housing
and take out the Iron laminate and coils. Then use the fan for pulse motors, just adding Neos.

@aether22,

I wonder if the fan motors (the AC ones, not the small DC ones.) can be used for testing the Thane systems?
One can mount the magnets direct (glue them on) onto the rotor thus create a very small distance for the
magnetic feed back direct into the axle and Iron rotor.

Thane,

Do you think such small Induction motors will display the increased RPM effect if driven via a Variac at
slower speeds and then add magnets to the rotor and see if the rpm goes up?

Groundloop.


[EDIT] Something like this?

Thane, I am proceeding to build, one thing though.

I am assuming that you are using 'magnet wire' in your coils?

YES OF COURSE

Not wire with a thick plastic coating?

NO WAY

I'll assume no answer to mean it's magnet wire.

ASSUME AWAY - MAGNET WIRE 22 G

And if you finish your new version before I do and find that a solid rotor doesn't work so well speak up.

NO I'LL KEEP IT TO SECRET LIKE EVERYTHING ELSE I DO - SO THE BAD GUYS WILL HAVE A REASON TO PUT ME "ON ISE".

One other thing, you could test with a single coil and a variable load and measure the current, see if the magnitude of the effect is linked in a linear way to the current through the coil or not.

OF COURSE IT IS THAT IS WHY I ONLY SHOW OPEN CIRCUITS (ZERO CURRENT - ZERO INDUCED COIL MAGNETIC FIELD) AND SHORT CIRCUIT ( MAX CURRENT - MAX INDUCED COIL MAGNETIC FIELD). LOADS BETWEEN OPEN AND SHORT (SAY 500 OHMS) VARY THE CURRENT IN THE COIL AND AFFECT THE FLUX FIELD DIRECTLY - I THINK LUC POSTED A GRAPGH SOMEWHERE. I CAN POST IT IF YOU WISH?

Oh BTW EMdevices, not sure if Thane understands your question but I don't, the motor is on the same shaft as the wheel not to one side of it so I can't make sense of your question. Never mind, just got it. you mean front and back not left or right.

MAKE DEMO WITH TWO ROTORS ONE ON EACH SIDE OF THE MOTOR (DRIVE SHAFTS) WITH MAGNETS FACING INWARD PLACE THE SOLENOIDS IN THE MIDDLE LINKING THE TWO ROTORS
NORTH ON ROTOR - SOUTH ON THE OTHER.

THIS WORKS VERY WELL!

[Heinstein]

IF IS ANYONE INTERESTED IN THE "HYSTERISIS HOMEWORK" QUESTION - WE WENT TO MIT ON THE 28TH OF JANUARY but ANSWERED THE HYSTERISIS QUESTION FOR OURSELVES ON THE 3RD OF JANUARY.

WE ALSO CONCLUDED THAT REDUCING THE HYSTERISIS OF OUR ROTOR COULD NOT RESULT IN SUCH HUGE EFFECTS - BUT WE WERE QUITE WILLING TO PAY FOR DR. ZAHN'S OPINION BECAUSE WE FELT THAT HE WOULD EVENTUALLY CONCLUDE THE SAME.

MvsH curves and their effect on machine efficiency
Thu, 3 Jan 2008 21:13:46 -0500

Hi Thane,

I have given some thought to Prof. Zahn's idea  that the M vs H curves are somehow affecting motor
or generator efficiency.

M vs H (magnetization vs magnetic field) curves are useful things. As the applied magnetic field H
is changed in magnitude and reversed in direction, the magnetization M in the material also
shifts. Eventually, M must snap into the state dictated by H. M is also limited by the characteristics
of the material, in other words, M saturates and further increases in H do not result in further
increases in M. As H changes, the operating point on the M vs H curve follows a loop around the
centre of the curve.

From the point of view of describing machine efficiency, the key feature of M vs H curves is the
hysteresis, that is, the space enclosed in the middle of the curve. The smaller the centre area,
the smaller the hysteresis loss, and the more efficient the machine using this material in a
magnetic core conducting flux. On the other hand, large hysteresis is exactly what you want in permanent magnets. Also note that hysteresis is not the only cause of losses in machines - friction, eddy currents, and ohmic losses contribute too - but they are not of immediate interest because they are not affected by external magnets.

In real life, one would never design a machine in such a way that its core material is driven to
saturation, so a real machine operates over a smaller range of M and H than the maximal values used to characterize the material. Applying an external static magnetic field would change where you
smaller working loop is located on the maximal loop. Could this affect the efficiency of the
machine? In a word, YES. Can one demonstrate what effect it has, and prove it? In a word, NO, because this type of phenomenon is difficult to model with
any reliability.

Here is an authoritative comment on the subject from a widely respected magnetics textbook by
Chikazumi and Charap (see attachments).
pg 291:

"Since, however, the actual mechanism of magnetization is very complicated, it is not so easy to
construct a real hysteresis curve on theoretical grounds."

I'm attaching some excerpts from this book including this passage and bibliographical information.

In summary, what this means is that Zahn can't prove that his theory is right, and I can't prove
that it's wrong.
