Re-Inventing The Wheel-Part1-Clemente_Figuera-THE INFINITE ENERGY MACHINE

[bajac]

Because of the information provided in my previous post, I am changing gear again! I will not pursue the construction of the rotating device shown in the 1902 Figuera's Spanish patent #30376. Instead, I started the construction of the Figuera overunity transformer shown in his 1902 Spanish patent #30378.

As I already said, the devices shown in these two patents work on the same principle and have very similar structures. However, the overunity transformer is much simpler construction and does not required any type of electronic device or mechanical connections with motors. And, I already have all the components.

It is important to say that the feedback used for self-excitation should be decoupled. Otherwise, there would be a risk of voltage instability. For this purpose, I am planning on using a 1KW UPS that I already own. The feedback loop will consist of two connections, a connection between the output of the transformer and the input of the UPS, and the other connection being between the output of the UPS and the input of the transformer.

Let us see what happen!

Hi antijon / all

it say, with same numbers of secondary winding, bigger  wire or bigger diameter will also reduce the resistance.

I will need your English expertise to help me out on understanding the message of a discussion between Mordey and others in the year of 1893. During this time, there were a lot of discussions, arguments, and even jealousy among well-known engineers that resulted in the standardization of the performance of today's electrical system and its components such as transformers, generators, motors, etc. I am specifically referring to the discussion for finding the best method to test the generators.

There was a race to be the winner of what would become the standard for testing the alternators. It seems that two of the pioneers of the generators with ironless disc armatures, Mr. Mordey and Dr. Hopkinson, were under the gun. For instance, Mr. Mordey was being heavily criticized for proposing a method consisting in configuring half of the coils of an AC alternator as a motor and the other half as a generator.
I am under the impression that the crazy results of the testing performed on the ironless disc armature alternators were not published because of the fear of making a public ridicule and lose the professional credibility. The following is a quote from an article published in the journal THE ELECTRICIAN, MARCH 17, 1893, and title ON TESTING AND WORKING ALTERNATORS found on page 574,

"Now it was to be observed in the interesting method which Mr. Mordey had described, and the extension of it described by Mr. Miller, that the stress on the shaft was not tested at all, and it might be that the shaft would be weak or the bearings might heat when the shaft was required to transmit 100 H.P., which would not come out at all in the method of testing described. It was quite clear that if one had not an engine giving more than 10 H.P. one could not in any way transmit 100 H.P. through the shaft. It might be objected that the method he had spoken of resulted in a distortion of the field, and the result would not truly represent what would happen if there were no distortion."

I showed this article to a colleague of mine and he agreed with my interpretation that it kind of looks as if the result of the test was given much more power output than what was being input. What do you think? Do you agree? Or, do you have a different interpretation?

To the above criticism, Mr. Mordey replied on page 576 by the end of the article:

"Some two years ago he [Mr. Mordey] described an experiment with an alternator in which one coil was taken out of the circuit and merely connected to a voltmeter. The other coils were then loaded from nothing up to full load and the excitation kept constant. He took that to indicate that the reaction of the armature on the field was not appreciable. He thought Mr. Kapp's curve was not a good curves.  It appeared that the machine was going to break out of synchronism at 2 ½ times the best current. In his curve he got up to 20 times and did not break out of synchronism. With reference to Mr. Harrison's experiments, he (Mr. Mordey) had had a good deal of experience of alternators, and have tried to find the faintest difference o field-current when the whole of the armature-current  was thrown off suddenly, and had never seen in his own machines the slightest flicker in the exciting current. Mr. Swinburne had criticized the modification of Dr. Hopkinson's method on grounds that were not quite fair. He was trying to test an alternator; he was not trying to test an engine, or a boiler, or a belt. Really the alternator had to be driven somehow, and for the purpose of his argument his machine might be direct-driven. As to the side pull of the belt, he did not think that was a very serious matter. He did not think the loss in the bearings was a difficulty, and did not think the reduction of efficiency by side pull of the belt was to be traced to the bearing, but the belt."

From the above it is noted that the efficiency of these machines was too good to be true. Critics, who were also prestigious engineers, were looking for any other factors to discredit the test resulting in "unreal" efficiency.

Please, note that today's generators use protective relaying systems for disconnecting a generator that is out of synchronism. Because of strong armature reaction caused by sudden overloads, the shaft can encounter a fast jump in the torque that may slow down the rotor to a point in which the frequency of the induced voltage is affected. If the frequency is affected, heavy currents from the electrical grid could circulate through the armature coils. If this condition is not addressed soon enough, it could cause considerable damage to the generator structure. In addition, because of the mechanical stresses that strong armature reactions impose on the shaft mechanism of today's generators, careful attention must be paid to the design of the rotating shaft structure.

Mordey was heavily criticized for not providing "adequate design" to the shaft of his alternators. However, because the armature reaction of the Mordey's alternators was very weak, the bearing losses became negligible and almost practically any decent shaft size would have done the work.

It really amazes me that the critics of the time, who were very good engineers, could not realize what was going on with the ironless disc armature alternators. And, it keeps happening today. If someone had come to me when I was fresh out of college to tell me about overunity generators, I would have considered this person crazy!

I am attaching two photos and two sketches of the Ferranti's alternators. I am not sure but I think they refer to a 5MW alternator. Note the relative small size of the piston shown in the first sketch.

Thanks for the link Hanon. Actually, the principle that relies on opposing fields can be easily demonstrated. But, i think it's true that there must be an air gap or something similar to reduce the effects of one primary onto another. In my tests, two opposing primary coils will cause them to draw more current as one tries to reduce the field of the other.

Anyway, it is a completely different principle, just like the addition of flux that I demonstrated.

Oh, to build a generator on this principle, look at the illustration. With a three pole rotor, all North pointing out, the stator coils should produce an AC current. Because of the three poles, in operation, when one magnet is leaving a stator, another magnet is approaching the opposite stator. This will produce a combined EMF equal to a standard rotor with a north and south pole. The effect of Lenz's law will still produce a back-torque because the current generated will still oppose the change of the rotor, but because there is no North-South "locking" the rotor to the stator, the running torque will be much smaller. I like to think that this design will show that the back-torque of Lenz's law is really very small.

Bajac, for some reason I couldn't download your document. Could you repost it, please? And yes, it does seem that they were trying to make a fool of Mordey.
