Free Energy will change the World - Free Energy will stop Climate Change
Free Energy will give us hope,
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

TFG_EM (Transverse Flux Generator using ElectroMagnets)

TFG_EM SUMMARY 25 December 2023 (DEH SL)

This Excess Energy Generator (EEG) appears to be almost too Amazing!

The initial Wind Ass Guess (WAG) approximations certainly indicate this could very likely be
the "HOLY GRAIL" of "Stand Alone, Fuel Free Power Generation."

Features include:

- Simple design, using only three (3) initial parts, easy to fabricate;
- Low cost; very good power to volume ratio;
- Requires no external Fuel source or Mover; it's totally self-contained;
- Easily expandable to increase output, or create a 3-Phase device, etc.;
- There are no moving parts, no noise or vibration, and nothing to wear out;
- High output power in a small size; 
- Simple electronic controller scheme.

All of the initial design analysis are encouraging enough to promote further development.

With a WAG ( not optimized) output performance of over 400 Watts with a footprint of near
212mm x 153mm x 76.5mm (8.35" x 6.1" x 3.1") being driven by a simple On/Off pulsed full
H-Bridge using a 3 Volt 100m Amp (0.3 Watt) supply source; this TFG_EM
concept provides some great promise for future EEG developments.

A "cleaning up" before any optimization and new design and development. Attached a few
files to clairify some items. Sorry if there are any repeats...

Hoping you're all having a Great and MERRY CHRISTMAS!

Looking forward to the NEW YEAR!

EDIT - changed the driving source to "3V 100mA = 0.3W" (500mA will saturate the Pole, unless you're using only a few turns) - sorry, a typo?  >:D

You might try increasing the cross section of the laminate stack and wire turns.

Here are some figures from a transformer calculator with common grade electrical steel.:

Cross section mm --- max power in watts

29 x 29 ------------ 65.9
50 x 55 ------------ 756.2
56 x 56 ------------ 983.4

Discovery consists of seeing what everybody has seen and thinking what nobody has thought.

Thanks Cadman,

This week I hope to construct a model where the dimensions are variables. This hopefully will allow
easily changing these and then doing some step by step comparative analysis.

Not sure exactly how AEDT handles the cross section of the wire turns but it does calculate the "J" term
so it might take the "fill factor" into account since it allows the number of turns to be entered, but not
the wire guage. We shall see...

Curious to see if the device can be scaled based on lamination stack size (or simply the Pole size). Also
need to link the model with the Thermal analysis module, and some other things.

Interesting and lots of fun!

Regards, and Happy New Year!

Hi Cadman,

Before I spend time trying to do any comparative analysis on this "WAG" device I thought a review of
other promising topologies (primarily stator pole schemes) would be a good idea. Don't want to get
too "wrapped-around-the-axle" before taking a broader view of what might work better.

This paper (attached), and several others, look into a variety of designs, so I'll review these first.

If you decide to review the paper a bit, keep in mind the PM's are replaced with EM's and the generator
is motionless so the related problems/concerns with torque, cogging, flux leakage, gap (no gap required)
and so forth are somewhat moot. Other things, like RPM are arbitrary - we can easily control these
(we determine the drive frequency - osc freq).

You can likely appreciate why this (new) design approach is interesting and so much fun!

 PS - found Fig. 10 interesting.

Another paper worth reviewing.

Has some good general information as well as design stuff.

Again, keep in mind we are replacing the PM's with EM's.
