##### Stanley A Meyer Mechanical Pump EPG coil parameters
« on: February 08, 2021, 04:05:44 am »
[An intrinsic portion of the Stanley Meyer technology had inductors, chokes and coils as important components
if devices. The voltage intensifier circuits( VIC)and the electrical  particle generators (EPG)
Many of Stanley Meyer's patents and publications provide diagrams provide the general description or have live
drawings that lack  exact component values of the resistors, capacitors , coils and chokes. Fortunately the high resolution
photographs from the L3 storage unit and by Don Gabel, The Orion Project and others allow for many printed circuits
to be closely  reconstructed.  The following article is related to the photogrammetric analysis of coils and inductors.

The values of the capacitors and resistors is much more straightforward using programs that match color code bands on resistors
with values and  OCR image data files input cross-matched with component  files based on supplier catalog scans.

METHOD 1. Determine Length of bobbin, thickness or depth of winding,/the wire gauge and method of winding

The diameter of the outermost EPG channel or loop can be estimated.at  about 17 inches
Therefore the outer circumference can be estimated at  17 x Pi inches
By dividing the circumference by the observed number of coils an estimated length of each coil can be made.

A further refinement in precision can be made by subtraction of  the total length  L occupied by coil spacers.
So in the case where you count, let's say as way of example, 59 coils and 60 coil end spacers, each winding is
1/59th of the circumference of 53.4 inches or calculated at about 0.905 inches long.

Method 2.
Because of  the high resolution photographs available, estimates of  a coil can be made directly.
Using a known measurement such as the outside diameter of tubing  ie.  0.500 inches
in conjunction with a screen distance tool in Photoshop(r) or another program such as
Screen Caliper(r) the length of the coil can be made.

THICKNESS
Since the outside diameter of the core channel is known,  an estimate of the thickness of depth of winding
may be obtained by using  photogrammetry to estimate the  thickness of the winding.
The total thickness or height of the wound coil is first measured. Then the core diameter is then subtracted.
the resulting  figure is then divided by two. This is the height or thickness of the winding around the core

So now we have what is call a winding window with height H and length L.
H TIMES L = A   the area of the winding window. Think of it a a cross-sectional view of
the coil windings with the ends of each wire being viewed.
Something like this:

IIOOOOOOOOOOOOII
IIOOOOOOOOOOOOII
IIOOOOOOOOOOOOII
representing 3 layers of wire with 12 wraps (the II symbolizing the  coil dividers)
3 layers of wire by 12 wires wide or 36 turns or wraps of wire around a bobbin

IIooooooooooooooooooII
IIooooooooooooooooooII
HooooooooooooooooooII

In this exsmple, a thinner wire could be wound 18 times on the same length of bobbin.

NUMBER OF WINDS
Since the gauge of  the wire can be estimated with a good amount of precision
,the use of circle packing theory (see wiki) theory can be used to determine the
number of turns that can fit through this winding window( Area equals Height
times length.

One factor that helps, is that wires come in standard  thicknesses or diameters
For convenience the AWG  (American Wire Gauge) is used in electrical
and electronic work, Electrical wiring in the U.S. is often 10,12  or 14AWG
Electronic work is often  uses 18,22, or 30  AWG gauge wire
Whatever the reason the smaller the AWG number, the thicker or larger
the diameter of wire!!

The reason this helps in photogrammetry, is that the gauges are discrete values
Look at this table:

AWG      Diameter in inches           AWG     Diameter in Inches
10           .1019                                 20           .0320
12           .0808                                 22           .0253
14           .0641                                 24           .0201
16           .0508                                 26           .0159
18           .0403                                 28           .0126
30           .0101

The 16 gauge wire is about 25% thicker than 18 gauge
The 22 gauge wire is about 25% thicker than 24 gauge

Not to get too technical, but this is a logarithmic scale,  but the important  concept
is the PERCENTAGE OF DIFFERENCE BETWEEN GAUGES IS LARGE
in relation to the precision achievable in photogrammetry

This means for a given photogrammetric distance is it easier to pick out the exact
gauge of wire used because the precision of the that method is often less than 2 to 5%.

PACKING FRACTION

There is a branch of mathematics which describes how many circles of uniform
size can be drawn in a given area. It goes by several names but let's just call it
Circle Packing Theory.

By determining the winding window size, the  appropriate circle packing  fraction can be used to
determine a close estimate of the number of windings per coil. In the previous example
cross-section of a coil, it represents one type of winding

One type of winding known as square or precision winding has each layer of winding with
turns directly on top the wires in the layer beneath with no offset.

Another type is hexagonal winding, with the layers arranged more like a honeycomb

And thirdly there is a random type of winding with lots of crossover and gaps

The hexagonal packing is the closest or most densest  method of winding coils
with a value of 0.906  or about 91% of the area occupied by wire with the
balance of the area being gaps between the wires

Square geometry winding with  each winding of wire directly on top the
layer below(  No offset)   has a value of 0.785  It is not at close or dense
a winding as hexagonal winding.

A random wind often a more gaps but the packing ratio is highly dependent
on the size of the wire relative the length and width of the winding window

Consider for a moment two equally sized sheets of sandpaper.
One is coated coarse grade grit, the other coated coated with a fine grit used for
final sanding.  The  arrangement of the sand grains is random in both
cases but there are fewer grain of sand  on the coarse paper and
many more grains of  sand on the finer grit paper.
This is analogous to the number of random winding or wraps of wire in a given
cross sectional area on a bobbin. Intuitively very small wire gauges have a
higher  packing fraction than large. This is a difficult value to quantify

SO IN SOME CASES IT MAY BE POSSIBLE TO CALCULATE THE NUMBER OF TURNS
IN SOME CASES EMPIRCAL METHODS OR TEST WINDINGS MIGHT BE NECESSARY

As an example if the winding window is 1 square inch and the AWG  is 22, and the tighter hexagonal
winding factor is used(0.906) then    0.906 square inches of that window is occupied by the area of the wire..
The cross-sectional area of AWG 22 is 0.0005 inches.
0.906/divided by 0.0005 =approx 1800 turns

With precision or square winding a factor of 0.78 can be used resulting in an estimate of 1560 turns through
a 1 inch square window

SUMMARY

Basically the application of the above method may be used to estimate  the number
of windings for an EPG coil by photogrammetric means in some cases

A search of empirical transformer design charts might be instructive for this third case
of random winding.  Empirical  as well as advanced computer iteration calculations
are used

Method 3

MISCELLANEOUS COMMENT
POWER OUTPUT DEPENDS ON  METHOD OF WIRING PICKUP COILS

It appears as though the mechanical drive epg was wired in parallel  lower voltage and  and a
higher amperage due to more coils
While the multitier EPG was higher voltage due to fewer coils and  many windings which required of multiple tiers
It also could be that the effective value of the flux in the mag-gas systems was lower that the higher density ferro fluids
which might explain the need to operate at  90 ips velocity

Russ Greis has a nice build of the EPG that had jumper connectors at the ends of each coil so that the coils could be individually
So depending on how the jumpers were used the output amperage and voltage can be changed. The output voltage or amperage
can be varied but also be dividing the coils into 3 groups  resulting in a three phase system

Other  phase systems are possible such as six phase systems

A sixty coil  system   1*2*2*3*5= 60 will allow for 1,2,3,4,,5,6,10 and 12 cycle output
