1. Полностью убрать влияние вторички на первичку (при коротком замыкании на вторичке, ток в первичке не изменяется),
2. Первый пункт позволяет раскачать первичку в резонанс без негативных последствий.
Вот и всё

Просто подключить аккумулятор к катушке не получится, так как, во первых, аккумулятор имеет постоянную составляющую тока и, во вторых, не может перезаряжаться с изменением полярности... собственно, первое вытекает из второго.
Значит, аккумулятор к катушке нужно подключать либо через конденсатор, либо через ключ.
В первом случае, получается аналог параллельного контура, а во втором - последовательного. Интересно, на какой частоте должен работать ключ, что бы обеспечить резонанс в аккумуляторе?
Может аккумуляторы взрывались от бурного выделения газов при большом токе? То же произойдёт и при обычной зарядке большим током.

При той же величине связи между обмотками, увеличивается межобмоточная и межвитковая ёмкость, а за счёт увеличения расстояния между витками обмотки, растёт индуктивность рассеяния.
В результате, падает КПД трансформатора. Особенно это заметно на малых мощностях, когда КПД любого трнансформатора и так мал.
Увеличенная межобмоточная ёмкость применяется только в ВЧ согласующих и выходных широкополосных трансформаторах - так называемых, ШПТЛ (широкополосный трансформатор на длинных линиях). Осбенно, при согласовании низких сопротивлений. Такая намотка с увеличенной ёмкостью применяется при малых напряжениях и больших токах, когда обычная намотка не обеспечивает хороший КПД на ВЧ за счёт потерь на рассеивание.
В этом случае, межобмоточная ёмкость, наоборот, полезна. Связь между обмотками получается емкостной на высоких частотах диапазона и индуктивной на низких. Индуктивность обмоток, в этом случае, играет второстепенную роль, лишь расширяя рабочую полосу частот снизу.
Используется на частотах от 100кГц до десятков МГц. В ином коротковолновом передатчике таких трансформаторов больше чем транзисторов (до 3-4шт. на транзистор).
Так что, юзать такое устройство на частоте 50Гц...

Заметь, я специально юзаю на низкой частоте. Потому как на высокой можно насобирать много чего, а потом репу чесать "ШО ЭТО БЫЛО". Но как видишь и на 50Гц сюрпризов полно.
Потом, помнишь как легко рождаются новые сущности - связь между Q и CosФи. А здесь же простая геометрия. Q=X/R, а из прямоугольного треугольника сразу видно, что это тангенс Фи. А мы вычисляем всё через CosФИ, который по сути из этого же треугольника можно найти как R/Z. Ну а теперь дели хоть Q на Cos Фи, хоть наоборот, всё равно от треугольника никуда не деться.

Потому же у меня и возникли сомнения по ф-трансу с сабвуфером.

Если допустить, что зуммер может работать как параметрический усилитель (а результаты моделирования как будто это подтверждают, да и сам Хендершот выводил генератор на режим настраивая зуммер), то в левой части схемы генератора можно выделить структуру типичную для регенеративного приёмника того времени.
К тому же керны у катушек деревянные а сердечник вообще может быть из алюминия (судя по надписи на схеме). Так что скорее всего делал Хендершот не трансформатор с хитрым взаимодействием полей обмоток, а регенеративный приёмник свободной энергии.

Fuelless Motor Impresses Experts
W.B. Stout Says, Invention Works Uncannily ? Washington Thinks It?s Important ~ Built On A Radio Principle ~ Armature Winding New ? Invention Inspired By Young Son ? Lindbergh Flies Here
Detroit, Mich, Feb. 25 ? W.B. Stout, head of the Stout Air Lines and designer of the all-metal tri-motored Ford Monoplane, declared here today that he had seen what he characterized as an ?impressive? demonstration of the Hendershot fuelless motor two weeks ago in Pittsburgh.
Lester J. Hendershot, the inventor, and his associate. D. Barr Peat, who is manager of the Bettis Field at McKeesport, demonstrated the motor secretly yesterday in a hangar at Selfridge Field. This block test was witnessed by Major Thomas G. Lanspier, Clonel Charles A. Lindbergh and others.
It was explained today that the model used in the demonstration was a much smaller machine than an actual working motor capable of developing enough power to lift and propel an airplane. Its designers claim for it that it runs on an electromagnetic principle, bywhich it draws its force directly from the earth?s field, and through the properties within the motor itself transforms these electric currents into power tha can be delivered efficiently at a propeller shaft.
Calls Demonstration Uncanny ~
?The demonstration was very impressive?, Mr. Stout said. ?It was actually uncanny. I would like very much to see how a large model designed to develop power enough to lift an airplane would operate.?
Mr. Stout said the model he saw was about the size of the tiny motors used in vacuum cleaners.
?I was told that the revolutionary feature was a hereto unknown manner of winding the armature?, Mr. Stout continued. ?Hendershot said he had succeeded in winding it in such a way that it draws energy directly from electrical currents which exist constantly in the air or in the ground. Such sources of cheap and inexhaustible power, of course, never have been reached before. The small model appeared to operate exactly as Hendershot explained that it did.?
Neither Colonel Lindbergh nor Major Lanphier would express themselves at length on the test they witnessed yesterday. Major Lanphier admitted, however, that they were experimenting with it and referred all questions to Hendershot.
?He is the only one who knows all about it?, the Major said. ?Lindbergh has nothing to do with it, although he saw it.?
William B. Mayo, chief engineer for the Ford Motor Company, was in conference with Major Lanphier, Hendershot and Peat at Major Lanphier?s quarters today.
--------------------------------------------------------------------------------
Invention Result Of Dream
Hendershot Made First Fuelless Motor For His Son?s Toy Plane ~
The invention of the fuelless motor, tested at Detroit, was the result of a dream by its inventor, Lester Jennings Hendershot, who lives on ?the street back of the railroad? in this town of about 3,000 inhabitants, 15 miles from Pittsburgh.
Although Hendershot was on his way from Selfridge Field today and is not expected home until tomorrow, his wife told of his conception of the machine and how the miniature model was constructed from the parts of a worn out radio which had been given to the inventor by his uncle.
Several years ago the vision of a machine which would operate from ?earth currents? came to Hendershot in a dream, according to his wife, but it was not until last November that he actually started working on it.
His 4-year old boy had built a small airplane at that time and was considerably chagrined because it would not operate. The father was disturbed too, so he told his son he would build an airplane which would work. The result of that was the fuelless machine.
First Model Worked Toy Plane ~
When the miniature motor model had been constructed, Hendershot built a small airplane and placed the machine in it. A switch was turned and immediately the propeller began to move. The machie was not connected to any electrical current, but was running on is own accord from ?earth currents?.
For several weeks the little motor and the airplane rested upon a small table in the living room of the Hendershot home, which faces an unpaved street near the railroad tracks. One day D. Barr Peat of Bettis Field, the air mail port near McKeesport, Pa., visited the Hendershot home to see the model.
He immediately became enthusiastic and a few weeks later he and Hendershot were at Selfridge Field where permission was been granted to build a model large enough to operate an airplane.
Hendershot, who is only 29 years old, was born in Hyndmann, Pa. His schooling has not been extensive, although he spent a few months several years ago at Cornell University, where he took a few courses in mechanics. He has not been employed at any particular task and has been known as a ?freelance? worker. He has been a fireman and an engineer on the railroad, has worked in the mills near Pittsburgh, has inspected concrete and done electrical work. During the war he was a bugler with a machine gun company, but did not get overseas.
Still Wants To See ?How They Work? ~
According to his mother, he has always been interested in mechanics and when a child he would insist upon taking his playthings apart.
And that desire has not escaped him a man, for even now he takes his own son?s playthings apart to ?see how they work.?
It required only a few weeks for him to construct the miniature model of his fuelless motor, although he worked day and night during that time. He had a crude workbench in the cellar of his home, which was placed near the furnace, where it was warm. Early in the morning he would be there, tinkering about, and late at night he still could be found there.
Hendershot?s idea was that the earth currents which make the aurora borealis in the skies could be harnessed by man and made to produce power that would operate an engine.
The youthful inventor has no other inventions to his credit.
--------------------------------------------------------------------------------
Works On Principle Of Compass
Lester J. Hendershot first came to Bettis airplane field in McKeesport between two and three years ago, and soon afterward brought one of his motor models to the officers of the field for inspection.
The fuelless motor works somewhat on the principle of a compass, and the original model would always operate when pointing north or south, as does the compass, but would not move when pointed east or west.
Young Hendershot worked nearly two years to overcome this defect, and finally he brought a motor to the Bettis field that appeared to be working perfectly. This motor was installed in a small model airplane and the plane flew, but owing to the failure to rig it properly, it crashed to the ground during on of the experiments.
Constantly improving the motor, Hendershot finally interested D. Barr Peat, manager of the Bettis Field, in his invention.
After a short time several capitalist were interested, and a few weeks ago the motor was taken to Detroit by Hendershot and Peat for an exhibition.
While no person at the field was in position to say authoritatively, it was stated that the capitalists who become interested in the Hendershot motor have about completed their arrangements for the purchase of the invention, or for controlling its production.
The fuelless motor, it is said, appears to have tremendous power and easily made between 1500 and 2000 revolutions per minute on several occasions while being tested at the field. Pilots and mechanics believe it to be the greatest invention of the age, and all appear sure it will be a practical success as an airship motor.
It was stated at the field that the inspection of the motor by Colonel Lindbergh was made in the interests of the capitalists who were arranging to purchase the invention.
--------------------------------------------------------------------------------
New York Times (February 27, 1928):
Fuelless Motor Is A Generator
The Hendershot ?Fuelless motor? is not a motor at all but a generator, according to Major Thomas G. lanphier, commandant at Selfridge Field, Mich., where he with Lester J. Hendershot, the inventor, and D. Barr Peat, have been quietly working on an experimental model?
Major Lanphier said he first became interested in the Hendershot electrical machine several weeks ago through Peat; that in common with others he thought at first it was more or less ?bunk? but after seeing it work he became interested.
?I saw the first model which Hendershot built hooked up to a small electric motor of the type used to operate a sewing machine. It not only ran the motor but it burned it out?, Major Lanphier said.
Why this generator acts as it does, where the energy comes from that transforms it into power, Major Lanphier was not prepared to say beyond quoting Hendershot. It is the inventor?s theory that his machine draws its energy from the earth?s magnetic field. While unwilling to describe it in detail until pending patents have been received, Major Lanphier told a little about it. The first model consisted of a ring magnet less than three inches in diameter. Around the magnet were coils rigged as only Hendershot knows how to rig them, and another set of coils pass through the center of the ring.
"With this contrivance we burned out the sewing machine motor and we also kept a 6 watt lamp going with it for 26 hours?, he said.
The larger model which has not yet been hooked to a motor that will deliver power to a crankshaft, Major Lanphier himself helped build.
?We put it together out of stuff we picked up at the field and with it we lighted two 110 watt lamps?, Major Lanphier said. ?I think that we have got enough electricity in this second model to kill a man.?
The second model is built around a ring magnet, the outside diameter of which is seven inches and the inside diameter six inches?
It was suggested that perhaps the Hendershot engine was ?stealing? power from some big radio broadcasting station.
?We thought of that?, Lanphier said, ?but we ran it for 26 hours when stations were going and when they were not and we got the same results.?

New York Times (November 12, 1928):
May Seek Motor Patent
M. C. Kelly to Ask Five Scientists to Test Hendershot Device
Representative M. Clyde Kelly of Pennsylvania, it became known here today, plans to seek a Congressional patent for the ?fuelless? motor of Lester J. Hendershot of West Elizabeth, Pa., if five scientists approve the invention as practical. A Congressional patent gives the patentee full protection for 17 years.
Hendershot?s invention, which he describes as a ?magnetic induction? motor, was first announced in March. At that time in some quarters it was regarded with skepticism.
The motor, according to its inventor, is without visible means of power. It obtains its initial impulse, Hendershot maintains, from a precharged magnetic core, and its secondary and greatest power impulse by magnetic induction from the earth.
Hendershot today said several of his motors had been built here, and that one, which developed 60 horsepower, had been in operation for two weeks without recharging the magnetic core.

New York Times (February 28, 1928):
Explains Magnet In Fuelless Motor
Hendershot Says Shifting Its Field To east And West Causes Rotary Motion ~ Winding Of Magnet Secret ~
Inventor Asserts Engine Weighs But 4 Ounces Per Horsepower
Mildly indignant because the manner in which his fuelless motor gains its power had been misrepresented in dispatches from Detroit and Washington, Lester J. Hendershot today stated there was nothing mysterious about his motor, that the force that energizes it is the ?same force that pulls the needle of the compass, and there is nothing mysterious about that.?
The fuelless motor was not his objective, he explained, at the time he began his experiments some three years ago, when he first became interested in aviation.
?I soon learned that the ultimate development o aviation depended upon the discovery or invention of an absolutely true and reliable compass?, he explained. ?The ordinary magnetic compass does not point to the true north ? it points to the magnetic north, and varies from the true north to a different extent at almost every point on the earth?s surface.
?There is another compass, the magnetic induction compass, that indicates true north. But it must be set before each flight, and is not always reliable.
?I found that with a pre-magnetized core I could set up a magnetic field that would indicate true north, but I didn?t know just how to utilize that in the compass I set out to find.
?In continuing my experiments, I learned that by cutting the same line of magnetic force north and south, I had an indicator of the true north, and that by cutting the magnetic field east and west, I could develop a rotary motion.
I now have a motor built on that principle that will rotate at a constant speed, a speed predetermined when the motor is built. It can be built for any desired speed, and a reliable constant speed motor is one of the greatest needs of aviation.
The main secret of Mr. Hendershot?s invention, his Friend Barr Peat declares, is the method of winding a magnet in the motor so that it will rotate in the opposite direction than the earth revolves. He says there is no heat, because magnetic forces are cold and the motor is stopped only by breaking the magnetic field in the windings. The magnet in the motor, he thinks, probably would have to be recharged after about 2000 hours of operation.
Mr. Hendershot declares that one of his motors, complete and ready to be installed in an airplane would weigh little more than four ounces for every horsepower it developed, while the best of the gas engines now built weighs about two pounds per horsepower.
Mr. Hendershot says that altitude would not affect the efficient operation of his motor, for the magnetic influence of the earth has been found to remain the same as high as man has ever reached.
He said that the same principle which made his original model operate only when it was placed in one direction, north and south, will be developed so that it will provide a compass that will always indicate true north.

Seattle Post Intelligencer (February 26, 1928):
Hubbard Believes Mystery Motor Based On His Own Invention
Ex-Dry Agent says he worked out secret of utilizing radium power in 1919
by R.B.Bermann
Alfred M. Hubbard, the youthful stormy petrel of the Seattle branch of the federal prohibition office, may possibly be the discoverer of at least the basic principle behind the [Hendershot] ?fuelless motor? which was demonstrated for the first time in Detroit last week, and which is attracting the attention of such aeronautical experts as Col. Charles A. Lindbergh and Maj. Thomas G. Lanphier.
This was claimed by Hubbard himself yesterday. While he said that he has been able to learn none of the details in connection with the Detroit demonstration, he declared that he was inclined to suspect very strongly that the motor was simply a development of the apparatus which e himself demonstrated in Seattle as early as 1919.
Driven By Radium ~
In 1919 Hubbard represented the apparatus as being capable of extracting electrical energy directly from the air, but he admitted yesterday that this had been merely a subterfuge to protect his patent rights, and that, as a matter of fact, it had been a device for extracting electrical energy from radium, by means of a series of transformers which stepped up the rays.
He declined to go into detail in regard to the exact manner in which he managed to extract power from radium ? but said that, so far as he had been able to determine, there was no great difference between the Detroit machine and his.
?I never heard of this Lester J. Hendershot, the Pittsburgh electrical engineer who is demonstrating the motor, ? Hubbard said, ?but it must be remembered that I worked on the invention for two years in Pittsburgh ? in 1921 and 1922. It was a Dr. Greenslade who represented the people who were financing me at the time ? but, of course, if the people who bought out most of my interest in the invention were to bring it out as their own machinery, they would probably do it through a man with whom I had never worked. I was employed by the radium Chemical Company at the time I was working in Pitsburgh.?
Sold Interest ~
While Hubbard declined to disclose the exact amount that he had received for his invention, he made it clear that he had sold out a 75% interest in what may prove to be the greatest scientific revelation of the ages for little more than a mess of potage.
?When I made my discovery,? he said, ?I was only 16 years old ? and, until that time, I?d never even had an ice cream soda. So you can imagine that a couple of thousand dollars looked mighty big to me. I never hesitated for an instant when the people who were financing me insisted on taking a [missing text] kept demanding more and more of my rights.
Just Quit Cold ~
?But, at last, along in 1922, I suddenly came to the realization that if I acceded to their latest demand I?d have only 20% interest left, so I just quit them cold.?
Hubbard asserted that he has no intention of bringing any legal action against Hendershot or his associates for the present, at least.
?If he really is using my idea,? Hubbard said, ?and if it proves practical, it?s so big that 25% -- or 2% -- will bring in more money than I can ever possibly use. So I am not worried ? [missing text] when he went to work for the Pittsburgh people.
Hubbard went into retirement along with his motor for some time, but he made a dramatic return to Seattle and public attention a few years ago, when he was indicted for liquor conspiracy with Roy Olmstead, then acclaimed as the bootleg king of the Northwest.
Hubbard was duly arrested but, on the eve of his trial, the indictment against him was dismissed and it later came out that, while associated with Olmstead, he had turned government informer. Some time after this he came out in the open as a frankly avowed prohibition agent.

Priest Has Motor Run By ?Ion Energy?
Jesuit Inventor From Brazil Is Here To market Product, Now Undergoing Patent Tests ~ Not A Fuelless Machine ~ ?Inter-Atomic? Force Increases Electric Battery power, He Says ? Discounts Hendershot Claims
An Italian Jesuit priest from brazil announced here yesterday that he had invented a motor that makes use of ?interatomic? energy to generate many times the power it receives originally from an electric battery. The motor is now at Washington, where it is undergoing the Patent Office investigation.
The priest is the Rev. Antonio d?Angelo, S.J., a stocky, earnest little man who combines missionary work in Brazil with tinkering in his own electrical laboratory. He speaks no English, but told of his machine through his brother, Biagio d?Angelo of 1475 LeLand Ave., the Bronx.
Father d?Angelo became interested in electricity 20 years ago when he was a student at a Jesuit seminary in Naples. A year and a half ago he was sent out by his Order to Brazil to carry on missionary work at Ribeirao Preto among the Italian emigrants. He had to get a special dispensation from Bishop Alberto Gonzales of Ribeirao Preto to visit the United States where, so his brother had written him, fortune comes more easily to the man with a money-saving device. He came here in November 1927, and has urged his Bishop to extend his leave of six months.
The missionary priest does not believe in the Hendershot ?fuelless motor?.
?I challenge anyone?, he said yesterday, ?to use the magnetic field of the earth for running a motor. The energy from that would be too small.?
His motor, he said, could be used in the home to supply electric lighting cheaply, and even heating. He said that it could be used to run trains, airplanes and automobiles.
Father d?Angelo had a plan of his motor with him yesterday. He showed how it started to develop energy from an electric battery, and how this original impulse worked on the machine to generate many time its power through the ?electricity produced by the inter-atomic energy of the ions.?

Непонятка...
Я продолжаю знакомится с достоянием Теслы ? сейчас смотрел патент № 645 576 «Система передачи электрической энергии»
Интересным мне показалось описание источника G на стр.3, строки 118-134, стр.4 , стр.1-2
Итак: Источник G состоял из конденсатора 0,04 мкФ который заряжался от источника напряжением 50000 В и разряжался механически управляемым разрядником 5000 раз/сек на первичку С. Первичка С состояла из одного витка толстого кабеля с ничтожно малым сопротивлением с индуктивностью около 8000 сантим. (8 мкГн). Диаметр витка приблизительно равен 244 см. Полная индуктивность первички була приблизительно равна 10000 см (10 мкГн), таким образом в первичке происходили колебания с частотой от 230 кГц до 250 кГц.
А теперь произведем вычисления.
Резонансная частота контура из конденсатора 0,04 мкФ и индуктивности 10 мкГн равна 252 кГц, что практически совпадает с частотой, указанной Теслой.
Волновое сопротивление конденсатора и индуктивности на этой частоте равно 15,8 Ом.
Ток, протекающий в контуре, равен 3166 Ампер!
Какой же должен быть кондер, чтоб это выдержать!
Мощность равна U*I = 158 300 000 Ватт!
Откуда у него в те времена такой источник?
Чего-то я не врублюсь?
Кстати, о нашумевшей машине, которую переоборудовал Тесла под електродвижок и на которой он ездил в округе неделю без какого-нибудь дополнительного источника энергии.
Я все больше убеждаюсь, что он реализовал свою идею беспроводной передачи энергии на расстояния. Таким образом, где-то невдалеке стояла его вышка, а двигатель был настроен с ней в резонанс.
А энергия эфира ? это уже домыслы корреспондетов да пыль в глаза самого Теслы.

Практически так же работает трансдуктор (из которых я Ф-трансформаторы делаю). Обмотки, хотя и намотаны на одном сердечнике, но половины вторички включены встречно, по этому, ЭДС в них не наводится. Но ток первички меняет параметры сердечника, вплоть до насыщения, по этому меняется индуктивность вторички. Не знаю как в паратрансформаторе, но в трансдукторе, к тому же, сердечник применяется с нелинейной зависимостью проницаемости от величины магнитного поля (тока первички).

Если посчитать индуктивность по известной формуле (кому интересно самому посчитать, смотрите аттач - страница из книги), то индуктивность катушки с указанными параметрами не достигает 5 мкГн при диаметре провода 10 см. Индуктивность увеличивается с уменьшением диаметра провода, но даже при диаметре 1 см она только переваливает через 5 мкГн. Но там шина, думаю, потолще сантиметра...
Потом, выражение индуктивности в сантиметрах?... не понятно.

Откуда у него в те времена такой источник?

Если посчитать индуктивность по известной формуле
Кстати, если посчитать резонансную частоту для 0,04 мкФ и индукт. от 8 до 10 мкГн то частота тоже будет больше 252 кГц. Тоже как бы не лепится.
Но согласись, значения близкие. Я просто даю скидку на погрешность измерений и измерительных приборов в 1900 г.

Я в том смысле, а не зарыт ли тут эффект сверхединичности?
Может, источник был всего 10 Квт, а все остальное откуда-то?
