Motor Generators

[bistander]

Well, electronic nonsense of modern science. Forum members are trying to sell you this as the truth.
A very fresh video from a master who makes generators and wind turbines in his garage. In the video, the master converted a regular asynchronous motor (1.1 kW) into a synchronous generator with a rotor on permanent magnets. He carried out control measurements of the no-load voltage and under load of 9 - 9.5 Ohms.
Dear defender of electrons, explain where the part of the EMF that was measured at no-load went, and under load it is no longer there.
...

Rakarskiy,

Refer to the attached diagrams and equations, found in so many textbooks.

The explanation you seek concerns the difference in the terminal voltage between loaded and no-load conditions. It is obvious that difference is the two terms containing the armature current, jI_AX_S and I_AR_A. For the no-load or open circuit terminal voltage, V_t, equals E_A. Under load, I_A is present and there is a voltage drop in the armature winding and reactance so V_t is lower than E_A.

Are you serious, where is the calculation? Solving the problem involves operating with real results.
An equation is not everything, there must be a confirmation. Dear opponent, your statement is a profanation that has nothing to do with solving the problem. You are not a professional, I would not trust you with any analysis.

SOLUTION BASED ON AVAILABLE DATA:

We take the data from the notes of the master (who does not care about my concept or your equations), he does this based on the fact of the measurements taken, and very correctly.

rpm - 400; E = 262.1 V; U = 85 V; I = 9 A; Rload = 9.0 Ohm.

(Load resistance - rheostat 9 Ohm, with all connections and connecting wires approximately 9.4-9.5 Ohm).

The resulting voltage drop is: ∆U = E - U = 262.1 V - 85 V = 177.1 V. Knowing the current, we can determine the resistance at which this voltage drop occurs. R = ∆U/I = 177.1 V / 9 A = 19.6 Ohm.
Let's check the load resistance: Rload = U/I = 85 V / 9 A = 9.44 Ohm.
Let's subtract the load resistance from the total voltage drop resistance to get the source resistance: r = R - Rload = 19.6 Ohm - 9.44 Ohm = 10.2 Ohm.

Let's check the solution with my method

∆U / (Rload + r) = I = U/Rload
177.1 V / (9.44 Ohm + 10.2 Ohm) = 85 V / 9.44 Ohm = 9 A.

------
The author does not measure the resistance of the windings of the three-phase stator of the asynchronous motor with a power of 1.1 kW. (he did not rework the windings, but only made a rotor with permanent magnets, turning the AC motor into a synchronous generator). We can clarify the resistance of the windings, according to known data. For example, there is a lot of data on connecting three-phase motors to one phase, where the resistances of the windings are indicated.

A screenshot of such data for a single-phase motor indicating the resistances for a 1 kW motor.

Resistances are taken from this resource: https://imperia-comforta.ru/soprotiv...gatelya-1-kvt/

One winding from the star for a 1 kW motor is 6 Ohms. For a 1.1 kW motor, this resistance will be within 5 - 5.3 Ohms.
With a series connection, like a star, like the author of the video, the resistance will be 10 - 10.6 Ohms (in our case, 10.2 Ohms).

So everything is as if by notes, a real example and my solution.

You can shove the theory of electrons in electricity up your ... well, you get the idea. Which of us is lying? You are a liar.

Hello Rakarskiy,

Your numerical example sounds like the same that you used a few days ago. Still the numbers don't make sense. I pointed out some serious issues which I see have not been addressed. You make it far to complex.

Simply measure the generator terminal voltage at rated speed and excitation. Then connect your known load resistance, still at rated speed and excitation. Measure terminal voltage and current.

Armature resistance = (no load voltage - loaded voltage) / current

What's your problem?

Don't call me a liar for posting fact and truth.

[Rakarskiy]

Yeah! There's no cure.

What does normal alternator speed mean?
The garage foreman has correct measurements on the alternator terminals at idle (no load) and with load at different RPMs.
Second, what is the excitation? If the rotor has permanent magnets, and this is the maximum magnetic induction of excitation (constant).
Third, the calculation I made for one measurement position, you can do it yourself for all the others.

I do not recommend anyone to deal with you in terms of analysing electrical circuits and electromechanisms.

Regards!

"What does normal alternator speed mean?"

Rated RPM at rated load.
Look at nameplate or manufacturer's specification.

"what is the excitation"

On typical generator, it is field current. On permanent magnet generator it is the magnet(s).

What was the garage foreman's measured no-load terminal voltage measured at open circuit?

Like I say many times and always mean, don't take my word for it, look it up, using reputable sources. You'll find that I post truth and fact.

Just for reference.
This is a simple setup with a generator coil and a motor coil run on a bit over 12 volts. These are the principles I have used in my big generator. Like I said, it's a simple 7th grade science experiment to see the principles in action. If you bother to build it. The machine in the video has all north magnets on the rotor, so I bias the coils with the correct polarity of magnet on the BACK of the coil to get the best effect as a motor coil and a generator coil. I also use magnets in OPPOSITION to both the generator coil and the motor coil to show the effect there. YOU be the judge of whether it has an effect or not. I know what I see on the bench despite what individuals here have said. By the way, the amp draw goes DOWN when the opposition magnets are put in place.

The PROPER size magnet at the PROPER distance will show a better result than what I demonstrate in the video, but it is the principles that are important.

My two friends who were having work done on the two versions of the big generator ran up a $5,000 bill at the machinist, so the gens have been in the shop for months, and won't be out until late October. One of them, who is a doctor, had a stroke, and he was providing the capital for what they were doing. Eventually I will have an actual machine to show. My buddy in Florida, who built my black machine, has his up and running, and is working on getting the amperage out of the coils that I was able to get with my coils. He was recently successful, so I may eventually have some video of HIS machine running also. Only time will tell.

The systems I am devoting my time to have no moving parts and are QUIET. After years of working with the generator and having some near misses with exploding rotors, it is nice to have a quiet setup that outputs power. There is always a danger when working with electricity, but I feel SO much safer!

A very clear example of magnetic Anapol!

------------------------------------
Addendum:
At one of the physics sites, the topic of anapole and anapole moment (the correct modern name is toroidal moment) was discussed. Where the physicist pointed out that all this is not new and is used in electrical engineering with closed magnetic circuits. Naturally, she cited that everything is in wikipedia:

Toroidal moment - Wikipedia

She also noted that there are differences between the existing curricula of schools and technical universities. Specific knowledge on the subject is needed for a narrow circle of specialists. In one of the universities in the USA all this is taught in a detailed form, but exactly for those who will be engaged in it.


967681910.jpg
In modern physics, a variant of electromagnetic induction (Figure B) is described as toroidal toroidal moment.

Magnetic toroidal toroidal toroidal moment and its relation to the magnetoelectric effect.
The presence of a magnetic toroidal dipole moment T in condensed matter is due to the magnetoelectric effect: the application of a magnetic field H in the plane of the toroidal solenoid leads, through the Lorentz force, to the accumulation of current loops and thus to an electric polarisation perpendicular to both T and H. The resulting polarisation is Pi = εijkTjHk (where ε is the Levy-Civitas symbol). Thus, the resulting magnetoelectric tensor describing the mutually correlated response is antisymmetric.

Functioning of the device described in my publication, is based on the principle of EMF in closed magnetic circuits like all synchronous generators. Dr Holcomb's generator works on the same principle:

This is an episode that will not make the press salivate (because it contradicts the global electricity market). Andrea Rossi, in collaboration with RENAUT (France), demonstrated an on-board power supply that not only ensured the movement of a conventional RENAUT electric vehicle, but also charged the on-board battery from 60% to 80%.

I have a test load (120v DC motor) running on a 12 volt battery. I have a second identical motor running on an identical battery connected to a specific TEST circuit. The motor on the TEST circuit will run 3 to 4 times as fast and (at the same time) 4 to 5 times as long, on the same amount of power. Our understanding of how to use DC electricity PROPERLY is incorrect. I've been saying that for years. Nobody listens. I run things in my shop the correct way all the time.

[Mario]

Hi Dave,

nice to see you're still around. Is the setup you mentioned still sort of based on the 3BGS principle (or simplified with DC-CD converters), or are you working on something else? I AM willing to listen

Mario

Lots of things have kept me from posting about the generator on this forum. Mostly because my time is better spent working on projects than arguing with folks who THINK they know what they are talking about, but actually have NO idea. My machine is still in the shop, and hopefully the guys will have paid the bill by the end of the month to get it OUT. But my friend who machined it for me in the first place, and shipped the parts to me from all the way across the US, has a duplicate machine he has been working with. He sent me a video today of a test.

Those who are interested, send me an email at dvdbowling@gmail.com and I will send you a link to the video. I am NOT posting it here.

But first let me say that just because he hooks up a bunch of AC devices Like 500 watt bulbs and 1,000 watt heaters, we ALL know that the light doesn't necessarily draw 500 watts and the heater doesn't necessarily draw 1,000 watts. An actual proof of concept demo DEMANDS watts in watts out comparison. But the person at the bench who has run these kinds of tests hundreds of times has a pretty good feel for when the lights are all the way bright and the heater is running close to what it should be at, so he feels pretty good about saying it is outputting 1600 watts, or close to it, and he does measure amperage and voltage output. I don't remember if he showed both or not. He didn't make this video for YOU. He made it for ME, to show me his progress and get feedback.

I want to make some things clear
He is running this at 1800 rpm. I run mine at 2800 rpm. 1,000 additional rpm or a 55% increase in rotor speed makes a significant difference in the output. I promise
He is NOT using the opposition magnets in this demonstration, just running the coils in a lenz neutral situation. WIth the opposition magnets added, the amp draw of the prime mover decreas significantly as I demonstrated above (in a video) in post 3996, and the rpm of the prime mover AND THE GENERATOR go UP, meaning greater output from the generator. With the addition of the opposition magnets the second motor he is using is NOT NECESSARY.

This is NOT a video to prove my claims. It's just to show that we believe enough in what we have seen to continue perfecting it. And it is getting us the funding to build a better version of the machine that will output MORE power and takes advantage of all the things we have learned from the building of THIS machine. Not all the tricks of the trade are demonstrated here

Any generator coil can be run in a lenz neutral condition WHEN YOU UNDERSTAND THE PRINCIPLES, and you do not have to wind them like Thane Heins does.
Opposition magnets reduce the amp draw of the prime mover, which increases the rpm at which it is able to turn the generator and increases generator production. TWO benefits you should not ignore. But do what you want. I'm not wasting my time arguing with anyone ever again. Email me for the link or don't.

Dave,

if you are willing to share, on what principle is that test circuit working on?

You can pm me if you don't want to talk here.

Time goes by, confirmations of the correctness of the concept of electric machines with closed magnetic circuits (which is not taught to a wide range of specialists, but only to engineers engaged in design) appear. I have made additions to my publication. This technology is the same as for a mechanical generator or solid-state according to the patents of Park Jae-sung and Robert Holcomb.
