Understanding Magnetism in a Syncronous Motor

[Mastiffman]

Would there be any difference of resistive magnetism created in a Syncronous Motor used for a generator as opposed to other types of motors?

Reason being is that I'm doing some research on generators for my own personal advancement and was wondering if there was a way and proceeding producing the benefit, to reversing the pole created, for a appropriate amount of Miliseconds, on a coil that has a load of current on it in a generator, decreasing the amount of Electromagnetic resistence that a nromal generator creates with a Load on it?

Thoughts...? TIA

You lost me at "proceeding producing..."

Proceeding, producing a benefit"

Better?

In other words, using a split second reversed pole (n or s?) to help cancel out or reduce the magnetic resistence that a normal Generator produces under load...

Just curious what these guys are doing also...

Hi Mastiffman,

I understood what you said, I watched the three video's and think I understand everything they show in the setup of the system. It is pretty much in-line with what I have said in several post in the past.
I found it difficult to understand the dialog while the noise of the system was in action and the walk-around was poor in quality, but it seems to me that there was no hoax of any kind.

It looks like a (window motor ?) acting as a generator, my thought is, the Variac and capacitor bank are key parts that allow control of wattage in and out. The mass of energy storage due to flywheel affect of parts in rotation, is much greater than the input and withdrawal of power taking place in micro, or even nano seconds.

I am curious as to why the sound was loud ? the running of my system even with compression of air seems a bit quieter.
I won't be rushing to him with a hand full of cash, but will try to keep an eye on his progress should he post more information.

Okay, thanks for the reposnse!

I'm interested to know what your thoughts would be about a Stator on a Generator that has Spinning Coils on the outside instead of fixed coils... Would this be a way to cancel or reduce back EMF?

Here is http://www.intalek.com/Papers/Handout3.pdf" [Broken]that is interesting...

Hi Mastiffman,
I'll engage a little bit, but I respect my privilege of membership too much to go very far in discussing such links as provided ( I do find them of some interest ).
My thoughts about back EMF being eliminated or reduced, is analogous to floating in a canoe and losing your paddle, or cutting off the flat blade portion.

In regard to your question of Spinning Coils, my guess is the suggestion of motor housing and rotor, being free to rotate in opposite directions ? if that is what you have in mind...I have done that with a small PM motor and it works to some extent, but as speed increases, control of torque between the two becomes delicate to control.

My best results was two motors powering one jackshaft, the control is having each armature connected to the other motors housing and all 4 parts are belted to the jackshaft. Voltage can be doubled from (my case) 120v to 240v rectified to DC, the armature speed is still at spec rating, but comutator/brush action is two fold and current is only limited by cooling abilities.

In my mind, magnets and electric, are good for fast switching and control of power flow, but the only real gain of energy will come from air in the surroundings that carries some portion of the sun's heating.

Right now I'm trying to learn how to make use of some Semikron SKKT 95/12E thyristors in a three phase rotatory converter design, the more I learn, the more I find that I need to know about other things.
I love finding things like this link and comparing to what I have. (a 7 pound 12v 200amp alternator)

Hope the link works.
