Hello everyone,

There is this concept that has been pressing me for years now and because I have found extremely low information on it, I have decided to share it with you. It is about the principle of the rotating magnetic field being produced by an induction motors stator for example, but instead of inducing a current in the rotor bars it induces a current in a specially designed coil that is wound on a core and positioned where the usual rotor is supposed to be. I have attached the patent of Alberto MOLINA-MARTINEZ, which describes in detail the principle. I have been trying to build it and the simple way to go around it would be to take a 3 Phase induction stator and build basically only the "rotor" part. In order to build that part, I need laser cutting services for silicon steel sheets (0.3 - 0.5 mm thick), which I cannot find in my area. At the moment I am stuck with this project, construction-wise. Until I get moving, I wanted to discuss one main aspect of this machine and that is:
*Is the rotating magnetic field generated by the stator, inducing current in the secondary part by flux linkage or flux cutting? If it is flux linkage the whole thing would be a transformer, an inefficient one because of the air gap between the parts and the low frequency (50Hz). If it is flux cutting, then it is a generator and in theory, it should be very efficient mainly because we are not moving mechanically a piece of magnetized metal near an electrical conductor. The only thing that moves is the flux. Also, in the case of flux cutting, the stator input should be independent of the "rotor's" output as in the case of a car alternator (I have one car alternator laying around and to energize the electromagnet it is required 12V at 5A, but the output, when the electromagnet is mechanically moved of course, can be as high as 12V at 36A, so there is no electrical input power vs electrical output power "equality"). I am judging that this car alternator analogy would be the same for the device we are discussing here, but once again, we should have an advantage because we are not moving the flux mechanically.
I want to hear your thoughts on this, if you have more details about the device, maybe you have built it, etc.
 
All the best,
Vasile

Hi Vasile,

Thanks for posting this Patent.

Some similar work is being pursued in the "Holcomb" related threads both here (OU) and on the
Overunity Research Forum (OUR). The concepts appear to be the same.

Some good information is also found in the "Serious HES derivative project proposal" thread here
on OU, as well.

There is a lot of active development work going on at the moment relating to nearly every aspect
of your post. In particular; Laser Cutting and Soft Magnetic Materials (SMC) [magnetic powders]
and a Computer Processor with MOSSFET drivers as these aspects are key to the design and
development.

I did a series of posts regarding a so called "LinGen" which includes Professional CAE Simulations
of a sweeping magnetic field in a stationary generator based from a Holcomb patent. Start here
and work backwards:
https://www.overunityresearch.com/index.php?topic=4261.msg103602#msg103602 

The Holcomb (HES) website (Commercial R&D) also contains a bit of technical information:
https://holcombenergysystems.com/technology-breakthrough/

Welcome to the subject - hope this helps a bit and Good Luck!

Regards,
SL

Is the rotating magnetic field generated by the stator, inducing current in the secondary part by flux linkage or flux cutting? If it is flux linkage the whole thing would be a transformer, an inefficient one because of the air gap between the parts and the low frequency (50Hz). If it is flux cutting, then it is a generator and in theory, it should be very efficient mainly because we are not moving mechanically a piece of magnetized metal near an electrical conductor. The only thing that moves is the flux.

I always found the concept of flux linkage or flux cutting strange.

I can move a permanent magnet or energized solenoid towards an inductor or closed transformer and a voltage is induced. This supposedly represents flux cutting and/or linking. We can also use a transformer within a motor or generator like the Alexander dynamotor patent, http://rexresearch.com/alxandr/alexandr.htm. What happens when we are supposedly flux cutting an element which is also linking?.

I found through experiment that Faraday was correct and it does not matter how the magnetic field changes only that it does. There is no difference between flux linking or cutting when viewed from the perspective of the induced element and they look the same.

Think of it this way, if you were the induced coil you would see an approaching magnetic field like a wave front. It does not matter whether the magnetic field source is moving or the magnetic field is expanding. The magnetic field gradient or layers of changing field strength approaching look identical. This is why the person who discovered induction, Faraday claimed it does not matter how the field changes.

What has happened is that many have confused magnetic induction with electromagnetic induction when iron cores were introduced. For example, do a search on "magnetic induction" and we get millions of hits on electromagnetic induction not magnetic induction, hence the confusion. Now do a search on "induced magnetism" or "Ferromagnetism" and we can begin to see where perceptual mistakes have been made.

For example, we use an inductor to induce a separate iron core with no windings which is moving. The inductor is considered electromagnetic or moving charges(electro) producing a magnetic field(magnetic). However one magnetized iron core inducting another iron core is considered as induced magnetism/Ferromagnetism not so much electromagnetic.

This is what happens when many start lumping together and averaging things and ignoring all the finer details. We cannot rely on mainstream science or the internet in this respect. I really like Faraday and Ampere's original work because they were as common sense as it gets. As if to say, this is exactly what we did and this is what we saw and measured. Anything else anyone what's to infer has no application and is conjecture.

Thus it's no so much a matter of discovering anything more so understanding where some have replaced certain facts with opinions.

I carried out measurement EMF which is released in permalloy ring and then rotor of usual motor.
The source of the rotating magnetic field was not a three-phase current stator, but a true rotating permanent magnet from an industrial magnetic coupling. This barrel magnet from a magnetic coupling has four H poles and four C poles along its inner circumference. At least no one will say that this rotating field is not real. In the ring, the EMF developed several times less than in the three-rod rotor. Why ?

First of all, thank you all for engaging in this discussion with me.

OnePower, I agree 100 % with all that you say, but I have something to add. We still need to identify why is there a difference between the so-called flux linking and the so-called flux cutting. I like simple things, so, following simple logic, if we look closely, the only difference between them is that in a transformer, the inducer's (the primary coil's) magnetic field moves relative to the primary coil and the secondary coil, whereas in the case of a generator (let's take the example of a slip ring car alternator) the inducer's (the rotor electromagnet's) magnetic field moves relative ONLY to the secondary coil (the stator coil) and NOT relative to itself. That is the only fundamental difference I see.

Didn't I prove that there is no virtual rotating magnetic field by my experiment with an iron ring in a stator ? All stator cores going outside have one pole, they only switch in turn. That is, in the winding of my ring, EMF cannot appear as in a transformer, because the magnetic fluxes are counter. EMF can appear only as a result of virtual rotation. But EMF is not there.

Hello kolbacict,

Thank you for your interest in the subject. I have some questions:

1) What do you mean by H poles and C poles? Are you talking about geometry? Please post a picture of your magnets assembly that you have spun around the toroid and the dc motor rotor respectively. I would like to see them.

2) You say when you spun the magnets, the toroid developed less EMF than the 3 legs dc rotor. Well first of all the geometries are different, one is closed one is opened. Second, you have different coils on the two assemblies, with different inductances, resistances, etc. Third, you have eight magnets moving. The geometry of the magnetic fields when moving is weird. Maybe they are going against each other in the toroid assembly than in the 3 legs rotor assembly. Have you calculated how the magnetic field interacts with the coils? Why not use just two magnets? At least we can visualize the movement of the magnetic fields easier.

Hello kolbacict,

1) What do you mean that you proved that there is no virtual magnetic field in your experiment with an iron ring in a stator. First of all, for induction, you used permanent magnets (Reply #3 of this topic), so what does a virtual magnetic field have to do with your experiment in the first place?

2) Okay so in Reply #5 of this topic you have jumped to a different experiment without saying so ( in the future please mention that you are presenting a different experiment so that we know that it is not the first one, from Reply #3 of this topic, or any other one from that matter). So in this latest experiment of yours, you have the toroid on the outside of a dc motor stator, a stator that has coils on it. You appear to be switching the inner assemblies coils in the hopes of getting induction in the toroid coil. How do you switch the coils? Do you use 3-phase current? How many coils are on that dc motor stator? Are there only 3? Are there more? Please present that so we know how the magnetic fields build up. You say the magnetic fields are counter. What do you mean counter concerning the pictures you posted? What are the North poles and what are the South poles? If you mean counter as in the toroid coil seeing a North pole building up from one side and another North pole building up from 180 degrees, then the induced currents "cancel" each other out so how in the world do you expect induction by any means?


3) I see you are truly interested in the subject but I think you should use what Alberto MOLINA-MARTINEZs patent says to use and that is 3 phase power, building up a 2 pole virtual magnetic field. The easiest way to get that is using a 2 pole, 3 phase induction motors stator. That is what I started with. Of course I use low voltage (12v), not 415v or 230v.

Hello.
My magnetic clutch like this one. Of course, that was uncorrect translate. The primary outer magnet has four N and four S poles. This is determined by a small permanent magnet. It successfully entrains the internal secondary rotor and rotates it.
And in my ring, the rotating field does not want to do. :(
Also pay attention to the electric motors from the pump of washing machines. In it, an alternating single-phase current successfully rotates the  permanent magnet rotor   ...

Why not use just two magnets? At least we can visualize the movement of the magnetic fields easier.
Probably so. I just had the finished product. A bipolar rotor still needs to be made. :)

You appear to be switching the inner assemblies coils in the hopes of getting induction in the toroid coil. How do you switch the coils? Do you use 3-phase current?
Yes. Everything is exactly like that.

I come back with the answer to the first post of this thread. I made some experiments and I can conclude that Alberto MOLINA-MARTINEZs idea of using the rotating magnetic field as a generator means, that presumably induces on a coil and produces more than its input, is incorect as far as I have seen. It acts like a transformer and not like a generator.
