Holcomb Energy Systems:Breakthrough technology to the world

So "phase rotor" means a slip ring induction motor in your vocabulary?
Thanks,

This reminds me of populism and a nursery rhyme called "Humpty Dumpty". In every book they show Humpty as an egg which supposedly falls off a wall.
In fact an egg has nothing to do with the real story and Humpty Dumpty was an English cannon, lol.
The English were being bombarded in a fortification and there cannon called humpty dumpty fell off the wall it was mounted on and could not be put back together again.

The popular story of a rotating magnetic field is similar. It's not a real field rotation because a magnetic field cannot rotate.
In fact, it's a progressively switched(Sine Wave) field which uses flux linkage to emulate a field rotation.
As one magnetic field/coil forward expands another magnetic field/coil behind collapses.
The flux linking between coils, links them, appearing as a single field when if fact it is switched.

The first clue should have been the term AC or alternating current. Logically a field cannot truly rotate when it ceases to exist in between an alternation/reversal.
The field expands(N) then contracts to zero then expands in an opposite polarity(S) then contracts to zero and repeats this cycle.
So we should be clear this expansion/contraction/flux linking may appear to be a rotation just as blinking christmas lights appear to move in a linear fashion however it is not a true field rotation... it's an illusion.

In my opinion it is these kinds of false beliefs,ie. field rotation, which hinders a persons ability to learn.
It's simply not true and cannot be justified with any real facts or justification.

Hi AC,
I disagree with you. But then we all can see things differently. Perhaps you missed it, but a few posts back I linked to the mathematical proof of the RMF. I'll see if I can find that and edit the link into this post for you.

But in short, it is the vector sum of the three H values from the three phase currents in the space and time of interest that results in an actual traveling flux wave or field.

I read with interest discussion between smudge and F6 about the deep nature of magnetism. I'm not prepared to go there. But I think that if it is possible that a magnetic field can "move", then 3-phase current applied to the stator winding can cause such movement.

A simple paragraph from a physics textbook (on the attached slide).

and another one of the teaching materials for students:

The magnetic field of the stator, superimposed on the magnetic field of the rotor, can both weaken and strengthen it. The influence of the stator magnetic field on the rotor magnetic field is called the armature reaction. The armature response is different for different loads. In the case of an active load, the total magnetic flux of the generator increases slightly, and the generator EMF increases. In the case of an inductive load, the total magnetic flux of the generator is reduced.

Definitely two different fields magnetic fields of the rotor and stator in the generator..

Science calculates the dynamics of this field,

if an asynchronous motor can create induction in a rotor cage, why is it not possible, in a static iron instead of a rotor, with a generator winding?

Logic must be logical.

The way you put it sounds convincing...if it did not have some errors, technical, though...

First, yes, in alternating currents, yes, whether 1, 2, 3 phase it works exactly as you have written above...

But what Pierre Cotnoir was showing, what I have been showing, and what Holcomb is based on...is a totally different concept.

It is NOT just about turning "One Field/Coil" forward and collapse another "One Field/Coil" behind...Sorry, but it is not.

It is about a whole Field RESOLUTION, which is based on AS MANY COILS AS possible in the Configuration, which generates ONE SINGLE FIELD, generated by many coils in SERIES and PARALLEL. As a MAJORITY of Coils are ON during the Operation, and only a MINORITY of Coils keeps alternating on both sides of the main Field Polarities (Only Two, North-South).

Now, the fact that "A MAJORITY OF COILS" are ALWAYS ON during the whole switching process, that keeps "alive" a Main Field configured by all other coils.

And so, YES, that main Field actually "rotates" as a whole, not like Christmas lights do...that "applies" when comparing to AC Currents, which "flashes" ALL coils in a sequential way.

Can You Guys see the difference between both ways?

And so, Typical Alternated Current CAN NOT DO THAT, no matter if it is 1,2,3 Phase type.

As a matter of fact, you have helped me to use your explanation as how AC does it...thanks!

I totally agree with Ufopolitics.
And that Main Field saturates the core so it behaves like a saturable reactor.
The  impedance decreases.
