There are also some interesting points about dc motor. How short must be break to let the motor still work ?

From the drawing it appears the cap is pretty large.  So the motor will continue to be powered until the cap gets maybe half way or more filled.  So the length of time the motor can run with the shorting commutator open is going to be determined by the size of the cap.  And of course the inertia of the motor should keep it going even for a while after the cap is charged.

Well that is if the cap happens to be depleted by the time the next switch closing happens. I dont know if the primary oscillation lasts as long as the off time of the switch.

If it does last as long, the cap could be charged one way or the other depending on the oscillation phase at cut off.

But im probably wrong, and will hear about it soon.

Nobody talks about what happens to the input A,B.
The motor is constantly spiking the supply because the interupter cuts it off from the supply. The windings of the motor have to get rid of their built up energy somewhere no?
The faster the make breaks ,the more spikes.

I agree that the Ozone piece,, that is the coil and parallel plates,, are just a demonstration of the use of the energy being manifested.

The motor and fan are multitasking however.

As the air is converted its resistance goes down,, blow the converted air out and the resistance between the plates goes back up allowing for a higher voltage to be placed upon the plates, so the fan helps

The motor acts as  the  source to charge the cap as well as the device that stops the current flow through the coil and the high voltage spike that hits the motor is partially reflected back into the cap.

The cap and coil are more of a pulse relationship and the cap does not need to be fully discharged either,, you could have several pulses before recharging the cap if so desired,, so the frequency of a pulse is what?

The frequency of the motor and the interrupter are logistical parts that are chosen to meet the needs of the output.

Think about the Ozone part only taking the output from the HV spike that happens when the current flow is interrupted.

The fan is just a blade attached to the shaft of the interuptor motor.
It was convenient to place it here. Yes it helps stabilize impedance between plates.
As well as move the separated anions and cations out into the room, before they anihilate each other.
All in all the fan reduces losses in the Ozone part.
The HV side of the circuit is not electrically connected to the oscillator circuit.
You can replace the Ozone maker with any of Tesla designs, the coil transmitter, or literally any of his devices. You don't need a secondary for the primary to oscillate.
The only thing the secondary does to the entire circuit is add a slight impedance in the form of
An inductive reactance through the secondary transformer windings.
An adjustment of the spacing between plates of the Ozone part, brings the secondary
Into resonance with the oscillator circuit.
Now, this was designed with the frequency in mind, so the Ozone plates are already spaced
appropriately. The only adjustment needed to get this working, was a variable resistance
through the interuptor motor to controls its' speed.


If you notice, the oscillator is exactly like any of his others. Except that here: an adjustable
Spark gap (threaded screw type) is replaced by the rotary interuptor.
Which is the primary function of the motor.
To spin the rotary spark gap interuptor
This is not a physical contact commutator like we use today.
It is a rotary spark gap. Gap distance remains constant, and the time variable
Is controlled by the RPM. This gives a consistent voltage, current, and frequency.
Voltage is controlled by the gap distance, just as before.
Current is controlled by the time the discharge points are within range to spark.
By necessity, the parallel Leyden jars have more capacitance than needed to provide
Constant current throughout the discharge.
If you scope the current through the discharge you notice it is a square wave
Vs the triangle wave presented by a stationary spark gap.
That's not important to our discussion, except to say that the current is consistent
During the "on time" of the primary winding.
As well as during the "off time" when the Leyden jars discharge.


Another important thing, which is discussed in the context, but not noticeable
In the drawing: the commutator in the motor is NOT a rotary disruptor but an actual
a/c commutator that drives the motor. Even though they both look the same in the drawing.
One is a commutator, one is a rotary spark gap.
These were generally part of the same device back in that day
Simply because you needed a motor to rotate the spark gap.
See image below


The parallel Leyden jars can be replaced by the capacitance of a Tesla coil
As shown in the second drawing in the patent. Also the motor that drives the inductance,
And the rotary interuptor can be simplified to a single coil pulse motor. As also shown.


All in all the primary oscillator circuit is an resonant LC tank.
Wherein: frequency = 1/ (sqrt) [LC]
L is the inductance of the motor and primary coil in series
C is the capacitance of the Leyden Jars or the parallel coil capacitance
   If a coil is used instead of the capacitors.


n/m the b.s. and theory people try to add into this.
Tesla told us exactly how this works.
It's as simple as his original oscillator, just uses more complex parts.


Think of the Ozone part as being an interchangeable component
Every one of his components needs an oscillator
The oscillator works with any of his components
Almost All of his patents are the same
Oscillator + component
Learn how to separate these in your mind.
The oscillator patent works as a stand alone oscillator
It's his 'driver circuit'
Once you learn these oscillators, everything you see Tesla connect
to a secondary winding - can be replicated with ease.


Here's an old rotary interuptor with motor attached

@ll

What does mean those words.

Ozone Patent.
Quote:
 "If air be forced between the plates P during this discharge, the effectiveness of the apparatus is increased and ozone is generated in large quantities"...

Could be, that him is talking about a Motor-generator, that increased its effectiveness with load. And the Next:..
"Continued production of ozone in unlimited amount".

I just asking!

Dear sm0ky2.

I have to disagree.

A " Spark gap " suggests high voltage, in Tesla's patent it's plainly a rotary switch, connecting/disconnecting the series/parallel L/C tank circuits.

Cheers Graham.

You are disagreeing with Tesla, not me. But do as you please

 Now that you have gotten this lets look at the improvement Tesla did to the primary source.

  1:) This is the "to be" discharged into transformer.

  2:) The whole circuit.

  3:) the magnetic controlled variable interrupter

  4:) the effect of this kind of discharge after transformatio

 Reference: http://tfcbooks.com/tesla/1892-02-03.htm
 

 The first picture is a no core version. The form is a wooden dowel that is supported by additional structure in the oil bath wood case. Tesla said it should be shielded by metal but for his purposes of testing the extremes of this setup he didn't use it in lab.

 The whole circuit is shown here in picture 2. The transformer is on the right after the magnetic variable spaced spark gap. This spark gap is a special beast. Sorta like a transistor but no power limits. The magnetic crossing filters the discharges or combs the plasma as it crosses the gap. This makes the electrode last longer on the transformer side of the gap. You could think of it as an infinite amount of division in the plasma after passing through the magnetic field flowing across the gap towards the discharge collector electrode. Instead of one massive conduction happening the conduction gets interrupted a vast amount of time. This causes the target electrode to get massive amount of hits in time instead of all at once discharge. You could think of it as a string of pearls flowing towards the target electrode. This would cause a minute variance in the current that once fed into a resonant system would build huge movements of current. In this case the current is being transformed into unbelievable voltages from an ordinary unit by the transformer and hence the need for an oil bath around that transformer. This is to keep it from producing OZONE and destroying the transformer coils.

 The transformer should be designed with a bifilar coil in the primary discharge path. This is to allow the reduced cemf response to NOT interfere with the forward EMF of the discharge. Dumping high current low voltage discharges, low in the sense of 1v-2kv (Tesla was used to working with millions of volts so that was low to him, into a regular solenoid wouldn't work because of the self inductance of that solenoid. It has to be a Heavy Bifilar coil in order for this to work and a high voltage winding as the secondary to transform the discharge into a high voltage impulse.

 You have to understand that this is leading into a plasma physics area and the movement of plasma around a high voltage source. This is just to learn how to attract the plasma to the system. Figuring out what to do with that higher density of plasma around this system is the key. What effects can a higher density of plasma around a magnetic device do? Does it make the effects of a magnetic system become enhanced like using an iron core does with magnetism?

 We know that plasma has magnetic channeling properties. We have proven this already visually and experimentally in the lab. What effect would enhancing the plasma field around magnetic devices do? Would it magnify it's output? Could this high density plasma field be used as a fluid and used in the same methods to gain advantage?? Is this what Tesla was making impulses into? The medium of the density of plasma?

 As a side note the magnetic filter across the gap has a singular direction or polarized flow. This one component could be responsible to making the discharges true impulses of one direction with no reversal of the gap. so this means one coil end will always be positive or negative in the output?
