No CEMF Transformer

[unimmortal]

Nice work Jim. I just found a similar thing with my pulse motor gen coils. You could short half of the coils and the other half jumped from 12.5 - 15.5VAC. No core connection though, just coils on the same horizontal plane.

Is the increase in current a result of the AC trying to push through a saturated core, caused by the shorted secondaries? How do you propose to alternate or switch the secondaries to induce the increased flow?

Is this similar to The Frolov Transformer?

No, Donald Smith and then Utkin. Here is Utkin's link - http://samlib.ru/editors/u/utkin_w_m/sec...kola.shtml
 Or this one with his experiments - http://samlib.ru/u/utkin_w_m/exper-2.shtml

I don't think "saturation" has anything to do with it. It's doing what any standard transformer does. With a standard transformer, The CEMF of the secondary causes an equal amount of power to be drawn from the primary. So 2 secondary's on 1 core cause both secondary's to double in power from the other coil's CEMF.  The difference is,  instead of that doubling of power being sent to the primary, it is being sent to another secondary that we can harvest from.

The secondary's do not get "switched".  The primary will need to wrap on the outside of the core so all that magnetic flus is forced to cut the lines of flux of the primary in 2 directions per 1/2 cycle.  As the original image portrayed.

   

Regarding saturation, we can find the point of saturation by increasing the input until the power in the secondary stops raising and levels off.  At that point, any increase in magnetism no longer adds positive benefit. I think I am still a long way away from saturation to come into play

Yes that link has an example here:

   

Seems most others do not understand.  Look closely at the bottom image of what I just posted above.  Look at the magnetic flux flowing around in the core.  Notice how that flux has to cut through the primary travelling UP,  then again travelling DOWN on either side of the outside primary. 

The direction the flux passes the primary determines which direction it will send it's reciprocal EMF.  As you will notice, it should Counter-Balance..  Half the time it will send it's induced charge to the source negative, the other half to the source positive, thus neutralizing all the secondary's CEMF

I am going to make a leap here and say this.  It may be erroneous.  And I think most won't understand what I am saying.

I tested the same ides but with winding both secondary's on 1 leg, where 1 is wrapped directly on the first- like a 2 layer bifilar. When it is like that, I short 1 output and the other completely goes to ZERO.  

I kind of expected this.  The magnetic polarities and interactions can be COMPLETELY DIFFERENT depending on how the secondary's are positioned.

When they are wrapped like a bifilar, the inside layer receives the induction from the core, and the outside layer induces from the outside of the first layer. The currents oppose each other and cancel out.

When the 2 secondary's are on separate core legs, the magnetic fields buck- like a standard transformer, thus increasing the output of both. 

I am not clear on it all,  but there may be a way to create a transformer which we can feed the output of a generator to, which could mitigate lenz drag on the rotor.

For those who are still unclear about the CEMF.  View this image below.

The Red Arrows show the direction of CEMF from the secondary per 1/2 AC cycle completing the loop.

The one on the RIGHTT is a standard transformer.  Notice how the Red Arrows cut the Input Coil in only 1 direction per 1/2 cycle.  This CEMF cutting the primary is the reason the input power of a transformer goes UP proportionally to the Output you take out.

Now look at the image on the LEFT.  Now the CEMF of the secondary is forced to cut the input coil in BOTH Directions.  (UP and DOWN).  Now that Input coil input current should only raise equal to the losses in the core.

If you check out Alex Manzanero on YT .....he has the coil set up with no back EMF .....Peace and love    Jay

Ok so I finished the transformer.  This is the inside.  2 coils 800 turns each of 24 ga

   

This is the outside.  595 turns of 24 ga

   

Powering the outside coil with AC,  if we draw current from 1 secondary, the input does not really raise.  The secondary CEMF will stay in the ferrite looped core. 

But when we draw from BOTH secondary's, the input DOES raise..  Meaning the magnetic flow in the core from each secondary is Bucking and exiting the core.  It would rather travel through the air than battle imposing magnetism.

I think this means just like current,  Magnetism can not flow in 2 directions in the same medium at the same time either..

This is interesting to me and may have a use.  Just not sure ATM.

Buenos días, la compartimentación del canal donde circula el flujo magnético se debe, para que todo funcione, dividir en dos direcciones y fluir sin oposición, parece una reacción rara, pero, se llega a ella entendiendo como funciona un transformador normal.
