[0239] Additionally, the overall efficiency is also affected
by core loss. This occurs due to hysteresis and eddy currents
in magnetic material. Such as 3% silicon steel laminations.

For simplicity, the BH loops shown in FIGS. 1, 4, 44, 45, 46.
and 47 are shown as straight lines. However, they are actually
loops as shown in FIGS. 38 and 39. The loops are caused by
the energy required to reverse the individual magnetic
domains within the laminations. The area enclosed by the
loops is proportional to the energy required. This lost energy
shows up as heat in a generator.
An equation that expresses loss in watts per cubic-meter when
frequency is expressed in Hertz and flux density is expressed
in Tesla:
    P=5.63*(Freq 1.532)*(B11904-B20.904)

[0243] CEPG generators have bipolar flux and saturate the
material in both directions. In that case B2=-B1 which results
in a large flux density change of B2+B1 and therefore there is
lots of loss.

This can be seen in FIG. 38. The large enclosed
area as 1 represents the loss for a traditional generator.

In contrast, the Switched flux generator of the present invention
uses unipolar flux operating on a minor loop. In that case, B2
is the same sign as B1 for a small flux density change of
B2-B1 and the loss is substantially reduced.

This can be seen in FIG.39. The small enclosed area identified
as 1 in FIG.39 represents the loss.

From computer simulations and the equation noted above,found
that B1 =1.329 Tesla and B2 =1.142 Tesla. Therefore, it is believed
that the ratio of loss for traditional generators to switched flux
generators could be as high as 7.104.

In other words, because of operating on a small minor loop, and
based on the above equation, it is expected that structures of
the present invention can achieve up to a seven-fold reduction
in core loss for each kilogram of material.

NOTE: Eddy Current Loss is reduced by using compressed powdered materials (SMC)
and Hysteresis Loss is reduced as shown above.

SMC Press Update

Very impressed with the fancy 30 Ton Press (expensive and heavy [~90lbs] but well worth it).

Busy doing some adamix compounds, etc. and testing - but becoming convinced this is a GO!
Easy to use and the preliminary results look good - cost effective powders and much quicker
than cutting, stacking and clamping laminations. Plus, the results, so far, are remarkably similar.

Attached a paper that sheds some light on why this 30 Ton (~420 MPa) might just do the trick.
Note the included "Final Pressure" and "Three Phases" graphs. Going to 60 Ton (~ 820 MPa) may
not be worth it for lab development work; production, probably worth it.

Well, this kind of wraps things up for me with respect to the "LinGen" fabrication approaches.

Hope Ya'All had a great Easter break!

Hello SolarLab

I think my material will be useful to you:

The generators OU at Flynn (USA) and Kornilov (RF) are built on this principle. Currently, both are dead and the technology is classified or destroyed.

the first machine on a similar principle was built in Germany (1934-35):

Well,here is picture of magnetic field within stator having single winding.
Maybe anyone will be interesting.  There is nothing rotating,but rotor nevertheless rotate.
the gap of line on the scope is where placed short circuit winding.

p.s.

the first machine on a similar principle was built in Germany (1934-35):

I have that on the benzin electric generator.

Hey SL,

Are you pressing laminations or a solid core? Any tips to share?

My build is almost ready to take take off. The laminate molds are done and the coil bobbins are printed and will be ready to wind as soon as the support material is cleaned off.
The rest of the powdered iron has been delivered, both kinds, and the 26ga wire is in transit.
