Why Virtual Rotating Magnetic Fields May Be The Key

[Jim Mac]

Next Plan Details...

Strip this stator down to bare-bones core.  Wind 18 Bifilar coils on each pole.  1 layer of each bifilar on the first 9 poles wire in series.  And 1 layer on the last 9 poles wire in series. We now have 2 phases that are fed with 90 degrees out of phase AC to rotate the field. 

I think this may even out the potentials

[Jim Mac]

Ok well, that plan is a no-go.  Not enough room on the poles of this stator to wind decent bifilar coils.

While I think about the right solid-state configuration, I am going to make it work in a way I know it will work.  Not ideal, but it should give me the data I need.

I will simply rotate a 2 magnet rotor around the 18 coils, producing 9 phases. The magnets will be large enough to cover almost 4 coils each.  Ensuring the phases are "high resolution".   

At least I will be able to verify the effects by recording RPM's / input / output.

I dropped the virtual rotating rotor that is fed with 2 groups of coils at 90 degrees into a Newman's style coil. 

The rotor is definitely rotating, and to my surprise, the input current actually went down a smidge when I shorted the output coil.



This is promising!  Maybe polyphase is not needed.  Correct me if I am wrong, but if the input does not raise when harvesting power and if we can get the output voltage higher than the input with more windings, does this suggest we can create a positive feedback loop by feeding the output to the input?

Edit-  Wanted to add, I have also been trying to replicate this effect with electromagnets with no success yet.  In theory, if we put 2 ac phases 90 degrees apart into electromagnets that sandwich a pickup coil (Figuera style) theory suggests it should balance the back-emf and the input should not raise.  But I have not yet obtained those results yet.  

This all goes hand in hand.  And if I can figure it out with electromagnets, I can probably couple the magnetic fields much mor efficiently than a spinning rotor.

I'm curious as to what effect will occur if the whole device is
slipped into a section of steel tube / stove pipe ?

Hi Jim,

I'm confused, as I recall the rotational magnetic field, has been simulated by some members in overunity.com, and they also claimed for COP >1,

What was their problem? what would be the differences of your experiments?

Hello there and good day.

You know I'm going to break out with the Thomas Edison speech lol. Just cuz some experiments fail, doesn't mean the idea is not valid.  Sometimes it takes thousands of replications to find the right ingredients.

Or the airplane. Many before the Wright brothers tried to fly, but they were the ones who opened the door.

Honestly though, I do not have overunity, and everything I say is just my opinion.  But if you want to post an exact method one of those replications tried at OU, I'd be more than happy to put my two cents in and evaluate the method they used.

This idea seems to have clear and concise reasoning Why it should work. The only argument against virtual rotation being able to produce more output than input, is the law of conservation of energy.

[Jim Mac]

Wow, it gets confusing..

So there is "rotation"  and "balanced uniform rotation".  My green rotor inside the tube was not exactly correct.. It was "rotating" but not optimal. 

to get "proper balanced rotation" with 2 phases, the poles of the coils MUST also face 90 degrees from each other as well as be powered with 90 degrees phase difference.

[Jim Mac]

Ok so with this new knowledge comes a new attempt...  Pole count of the rotor must be divisible by 4.  So little 8 pole stators are nice and cheap.  Just hope there's enough room on them to wind decent coils..  Will find out tomorrow once they get delivered.

Crossing 2 primaries in the middle between poles gives me balanced rotation with 90 degrees coil orientation. Now to balance Back- EMF..

With the four-phase output, the back-EMF generated in each pickup coil will be 90 degrees out of phase with the back-EMF in the adjacent coils. This is due to the fact that the pickup coils are evenly distributed around the stator and the magnetic field is rotating. The beauty of this is that the sum of all the back-EMFs at any instant will be zero due to the 90 degree phase difference.

   

My first attempts were part of my learning curve.  I don't give up easily...

But with the holiday, might take me a few days

[Jim Mac]

The 8 pole stators arrived, and they are no good..  The core metal is much beefier on some sides than others and are very uneven (material wise).  I don't know much about moped charging systems, but apparently they are designed for 2 coils to run the ignition stuff, and 4 coils for charging.  Whatever, I am not gonna waste time with these exact cores, as they are not balanced..

Instead I decided to grind-it-out and use a washing machine induction stator that was divisible by 4.  I hacked off the old windings, and wound it with 24 gauge.  I have 2 pairs of coils in 90 degrees orientation inside the enclosed core.  The resistance of each phase came out to 7.2 ohms and has 400 turns per phase, which is good enough to match my amplifier that can power 4 or 8 ohm speakers. 

   

Later I will try to get the wires connected and get her rotating..

[Jim Mac]

OK I got her rotating and I see a HUGE improvement.. The issue now is that the rotation is more "Diamond Shaped".  The 90 degree faces all rotate equally, but the 45 degree points where the coils meet create dead spots. 

I show the setup in this video and demonstrate exactly how to verify if you have true rotation and not just oscillation that makes the compass spin.

 

I consider this good progress!  Guests cannot see images in the messages. Please register at the forum by clicking here to see images. And I absolutely feel this rotation can be done with extreme accuracy.  Now to hunt around for more cores!
