Generator and Alternator principles of operation.

[rakarskiy]

I will allow myself some remarks.

Several factors are responsible for the formation of EMF in the generator phase wire.  Everything is based on the general Faraday formula [E = - dF/dt]. The main condition is the magnetic field, more precisely its magnetic induction value. When magnetic induction changes, an electromotive force is generated. The vector of magnetic induction for cutting the force lines of the conductor Bm (or the resultant of magnetic flux in the ring ANAPOL: Φ = Bm * C), then comes the rate of change of magnetic induction (in metres per second or frequency). The length of the conductor is already a constant component, but it is no less important. 

We have two formulas for the contact at cutting of the conductor by force lines [E = Bm*l*v*sin(a)] and for the anapole moment [E = 2πΦf / √2 = 4.44 Φf ] at the focus of changing magnetic flux where the conductor is placed.

This is the condition for the creation of electric potential difference - electric induction, at the ends of the conductor: zero and (+/- alternately).
 
If the conductor with induced EMF is closed in an electric circuit with a load, there will be another moment, electromagnetic induction (just the one I specified from Maxwell, in his equation to Ampere's law). The electric field (electric induction around the conductor - EMF) is converted into a magnetic field (magnetic induction around the conductor Bi). In the electrical system the measurement is Amperes, in the magnetic system it is Tesla).

All this is verified in the solution of an elementary problem (Link).

The electromagnetic torque of a generator, is also a consequence of this transformation, where the rotor needs to overcome the magnetic attraction between the magnetic rotor and the stator. In a solid state system, we need to get the magnetic field from the phase current, to vary linearly in time. This is the element of flux-coupling that almost all searchers overlook.

The current is responsible for the strength of the current in an electrical circuit with a load, where the generator is the source of the electric potential difference. It is called a current generator by its principle of operation, it does not produce current, it generates EMF.

I also wanted to tell you what the electrical generator design engineers told me. Designing of electric generators is the highest pilotage in designing of electromechanisms.  Almost all the features of such solutions remain in the respective design offices.

The first alternators were the simplest and made in 1832 by the French physicist Pixie and an unknown man who wrote a letter to Faraday. This I reviewed in my publication The invention of the electromagnetic generator.

Both of these generators had a permanent magnet for excitation and coils wound on cores. The maximum EMF in such generators is when the entire magnetic flux is shorted to ANAPOLE, The magnetic lines can in no way cut the coil conductor.

I have drawn a slide explaining the principle of EMF induction in the simplest core generator. I hope it will push you to the fact that you need to think and not everything that declare physics textbooks is reality. Otherwise there would be no conflict between engineers and physicists in this matter.

Rakasky..

Take your model.  Make the magnet stationary and orient it so the poles are Up and Down. Magnet does not move.

Now rotate a ferrous 2 pole rotor around the magnet.

Now the Moving Rotor's Mass SHRINKS the magnetic field on approach and GROWS on Exit.  



According to my understandings, we now have a full cancellation of drag.  We reversed the magnetic interaction compared to a normal generator, which the induced coil's field assists rotation of the ferrous mass..   BUT the assistance is negated by the counter force that will occur when the rotor is entering and exiting the magnetic fields of the magnets. 

This is the theory behind my current build happening at https://www.mooker.com/thread-159.html


This was the first build's results:

I am in the process of building it with bigger coils.  The first tests should take place today sometime.

Your comment is completely OFF TOPIC.

This Topic is about Discussion of EXISTING Generators and Alternators Principles.

NOT about showing off your development(s) plus links to YOUR site!!

I will delete your post here.

@floodrod

You got it COMPLETELY OPPOSITE at 180º WRONG!! on ALL "Your Theories" PLUS ABOVE STATEMENT!!

Whenever ANY piece of steel approaches a Magnetic Field it GROWS IT, IT EXPANDS IT...NOT SHRINK IT!!

STEEL IS ATTRACTED BY MAGNETIC FIELDS, FIELD EXPANDS ON THE CLOSE PRESENCE OF STEEL, NEVER "SHRINKS" !!

I am NOT going to allow you being spreading your FALSE "ASSUMPTIONS" ALL OVER THIS SITE!!

It will completely CONFUSE READERS HERE!!

I asked you VERY POLITELY ON A PRIVATE MESSAGE about this matter...

BUT, INSTEAD, your approach was ALL INSULTS.

And as you have asked me to delete your profile, I will just 'mute' it by now...my decision may change anytime.
