4 coil field modification

I will describe a method of magnetic compression using 4 copper magnetic
coils. These each contain 20,000 winds of 23 gauge wire @ 1000 ohms. I do
not know if this same method is possible using ferromagnetic coils. In any
case I am quite surprised that Joseph Newman, the king of all these
discoveries has made no mention of it.
About 1992 I put 4 of these coils in this described formation and was
able to rotate a 50 lb magnet about 450 rpm on 70 watts draw. I did not
consider this significant because once a load would be attached this rpm
would rapidly drop and I looked at the tremendous obstacles involved with
any copper magnetic motor. I did not pursue this matter any further after
that because I realized the only thing to be gained was experimental
information and nothing about a motor approach was practical.
At this point in time I became fascinated with Tesla's work and went
on
a different tangent of making huge coils and knocking out the power by
accident.
And as time goes by I wonder if anything at all is by accident. But
this was one of them.
Now the first thing one knows about Newman coils is that they work
from
side action which delivers a weaker force than a polar reaction between a
air core coil and the magnet. So looking at the simplest model it is
presumed that 2 side coils could be used instead of one to increase the
force on the rotating magnet, and experiment easily shows this to be true.
Now the coils I had were 13 in high and without thinking I saved until I
could get 2 more without thinking.
Of course one recognizes that 50% of the strongest force from the
magnetic interaction of the coils is missing in rotation on this simple 2
coil side model and so the next logical progression is to make a 4 coil
system in which 2 coils only turn on during that 50% period of max torque.
So when the magnet rotates 90 degrees another system of two coils turns on
ect. So one ends up with a box looking field coil configuration in which
the
2 coils that can most effectively rotate the magnet are turned on when they
are needed by the commutator. I reckon that anyone who wanted to improve
newman design would first try something like this, so thats what my
thinking
was...
Now the magnetic rotor was only 9 1/2 inch long so when the box
arrangement was concieved with 13 in length coils the magnet could not be
close to the coils in this arrangement. The dimensions of the coil had not
been preconcieved< one gets the only thing industry will supply for the
cheapest cost considerations...
So an accidental experimental field design was attempted because of
these monumental oversights on design where two of the coils would be
turned
around in which the 7 in diameter poles of the coil could face the rotating
magnet along with the 13 inch sides so that the magnet could sweep by all
coils in close proxity in what we might call this polar -side hybrid field
coil arrangement.
The very first thing that was noticed about this field coil
arrangement
was that when the magnet was in a position that gave torque from the side
model (poles facing side coils), and the extra pole coils were turned on{
that ordinarily would act as a weak force in the same direction}; instead
of
these two predicted forces acting in unison a CANCELLATION force acted
instead!! This showed as a magnetically dead or neutral action.
So obviously the next modification made was to determine what would
happen if one of these sets were then reversed in polarity. It was then
found that the STRONGEST torque of all positions of the magnetic rotor than
existed at the side position and NOT the polar which is what every one
assumes with biblical reverance from past experience and models.
In fact when the reverse application was made and the rotor was spun
and the generator action imposed on the coils in series were observed on an
oscilloscope it resembled a square wave much more than a sine.
I would not submit such a fact if it were untrue, there would be no
reason for it. For 8 years I have seen no possible application of such a
field arrangement, and generally see no reason for wasting time, time that
could be increasingly important in these days for other lines of thinking.
What it does mean however is that a magnetic compression occurs making the
side action what it is. This implies that polarity change via side coil
action could be simply accomplished by shutting off the polar coils for 180
of magnet travel. I tried this but it did not rotate the magnet very well
because when the pole coil fields collapse it interferes significantly with
the normal side coil. Or thats just my opinion of the observed results.
I hope to have the time to send this VHS tape record of operation to
those I promised to see it, but I am very busy with things and will try to
start making recordings of this soon. HDN
