Electromagnetic Generator Theory

[Classic]

@rakarskiy, in post #153 above you may want to use MMF and EMF instead of partial and full EMF, am I right ? 

Where MMF induce a curent and; EMF induce a curent and self induce due to electric potential.

One parallel RLC circuit produce high MMF to induce an EMF into an series RLC. But series RLC do not have enough MMF to induce a current in parallel RLC and practically there is no fight between opposing forces ... which means generation with less effort.

Ca you identify which RLC will be a permanent magnet in this case, parallel or series ?

Magnetomotive force (MMF) is used to calculate electromagnetic generators (alternators) with closed magnetic circuits. All alternators that operate in power plants are machines with closed magnetic circuits.  The magnetomotive force in the SI system is measured in amperes. In practice, to avoid confusion with current force, the term "ampere turns" is often used. The resulting magnetic induction in a closed loop is then calculated. 
        .
Next, when calculating the electromagnetic induction in a closed magnetic circuit, a formula called transformer EMF is applied.  E = 2π/√2 * Φf = 4.44 * Φf  [Toroidal moment = Anapole moment]

Engineers use it to calculate all alternators in power plants, while physicists deny it (paradox).
It is this paradox that I explained from a physical point of view, which in no way "physics dinosaurs with a bunch of utopian science degrees" want to accept.

Self-excitation in an oscillator and self-induction in an inductor coil are somewhat different in nature.  Self-excitation in an oscillator occurs by increasing the magnetic induction in the core, which is added by the ampere turns of the phase winding. Self-induction in an inductance coil can occur without a core, splitting into two components: electromagnetic induction around the conductor in the form of EMF (those peaks we all see on oscilloscopes) and a change in magnetic induction due to the toroidal moment phenomenon.

Yeah, the question is they really don't know ? They don't want to know ? Or they don't want others to know, they know ? Judging by constant absence of any studies I can guess which option NOT to consider. And I mean constant absence of any studies for more than hundred of years.

If anyone use the calculator I posted in previous message and keep everything constant apart from resistance may simply observe that powering constant a coil with DC while "modulating" only resistance I can actually modulate magnetic flux without the need to physically change anything else. And virtual magnet is changing its strength or shape defined as MMF (that's why is a magnet) without the need to physically move a real permanent magnet.

If you make sure the EMF induced in pickup coil (secondary) do not have enough strength to induce a MMF in primary you get what you are looking for. To make sure this is not happening you must drain secondary as in this case you are using a constant supply of DC and you don't want and don't need to recycle energy at this point here. You can recycle the energy by sending a portion of the output to the battery connection (not charging the battery).

I truly believe this is what Figuera describe in his patent and this is I was trying to say all along but unable to express much clear in this way. Probably if we consider this option we can see all coils are fired in the same time and number of coils is not related to number of contacts on commutator. Commutator is used just to modulate sequential through resistance MMF of primary. Our eyes are deceived by what we see ... very clever way to hide a secret in plain sight.

At least for me this way make more sense. But, also open my eyes for many other ways to generate electric power.

The problem is in the system. Knowledge of how a closed-loop generator really works is not needed even by 99% of electrical engineers. Do you know exactly which direction the current in the loop is from + to -, or in the opposite direction? Only a designer who designs electromagnetic machines needs this.

Let's take this good animation:

AC generator working principle

where I personally see contradictions that are insoluble with the general interpretation of the induction of EMF in a system with a closed magnetic circuit, with how the real EMF is formed.




There is another video with a visual aid of the simplest generator:

Simple explanation of a generator



The question arises, how can magnetic lines cut the conductor in this design? But students are fed a generally accepted lie.

Excitation of the turbogenerator rotor electromagnet (the one that is connected to the same shaft as a steam or gas turbine) is 0.5-3%, from the total output power of the turbogenerator. Electric power is [W=IU] If EMF is electromagnetic induction [E=-dF/dt], then mechanical power [P=Fv] expended for rotation is a condition, not the energy of transformation. If we rotate the magnetic field in the armature and not the armature itself without expenditure of mechanical power, we can calculate the efficiency of generation, it will be 3333%.

What could be simpler, take the armature of a DC motor, insert it into the stator with slots where the three-phase winding is wound, rotate the brushes around the collector. You will get electricity generation, but to build a consumer machine you will need the appropriate knowledge to perform the design. I described the simplest way in my publication.
