new here! several questions

@the_Big

I believe what he is referring to is not a motor belted to a generator.

but rather, both in the same device.

what it sounds like to me is a standard military issue power amplification dynamo

This is a motor on the outside, but there is not a load placed on the shaft.
rather, inside the diameter of the rotor, is another set of coils that acts as a generator.

This is used to power many of the systems on board warships of the Navy and Airforce.

I didn't forget this post.   What I perceived from your post above was:
The magnets, with the North poles facing outward---and weighing a lot less than the copper coils---are spun on a shaft using only the way, way lighter magnets on the INSIDE of the rotor to be reacted against the stationary 'stator' of the coils that requires a lot less power to input and then get a full power rating from the coils.
       The thing might be...?
The magnets MAY resist the coils---hysterisis?---and this might complicate the generation of power by the fact that it happens?   The resistance may show up as a leading, pushing effect as magnets approach individual coils?

eh, i think you are not getting what i was trying to type out, bigM.

"what it sounds like to me is a standard military issue power amplification dynamo"
correct, this is what i used to work on.

so what i want to learn from this post is to start back at the basics.  i want to start with a low power consuming pulse motor.  when i get that figured out(with your help), i wanna build the generator portion(same shaft), and lastly...... do what the name of this forum means.....  more power then input. 

i have seen so many videos on youtube.  this is nothing new, and has been accomplished before. 

why isnt there a motor-generator that can run a house off the grid?  its there, but i cannot spend several grand to purchase a unit from quantamagnetics.com.  nor would i personally want to.  i know hes gotta make his money but im not wealthy and i would rather make my own unit.

heres where im at:
so far i have a cd with 4 neos from a few old harddrives.  that is my rotor.
i mounted it to a burned up cd rom motor because the cd holder was still intact.
thats about it at the moment.

i have reed switches(mentioned above) and they keep sticking closed because of the current running through them in series with the coil.  yes, really simple circuit is what i started with.  i am now trying to scavenge some transistors to use for the reed switching portion to limit the current on the reeds.

i have wound a few coils that are very very small, just for testing.  this might be another problem im having.  i still need to purchase a few spools of magnet wire.  i was just using a few short strands that i had around.  i will be buying at least 2 different gauges of magnet wire spools but "damn" they aint cheap.  any advice on this would be great?  site to purchase?  recommended gauges?

the design i will try to pursue is similar to quantamagnets.  probably 6 magnets on the rotor. 

im not even close to that point yet tho. 
i have to overcome the reed/current problem, or figure out another way, timing/commutator maybe.  would like to stay away from a commutator set up tho. 
i still need to figure out the best coil type to use, how many windings of what gauge, bi-filar or not.  duno how i feel about bi-filar yet, duno enough about em yet.

i havent had much success with the cd project yet to move on to the main project.  i have not had a successful run of this motor yet.  pretty sure it is because i half-@s$ the coils.  two test coils, about 3ft of magnet wire, one wound around my pointer finger and the other around a screw driver.  i can feel the magnetism from each but i never get any rotation from the rotor.  im just holding them in place also. 

so that is where im at, and where i want to go.....
i wanna stop paying power bills.

and thanks again for everyones input.

here is what im planning to buy.

magnets
http://www.magnet4less.com/product_info.php?products_id=1158

maybe some different variations.  comments?  advice?  cheaper site?


magnet wire
http://www.magnet4less.com/index.php?cPath=9_20

not sure on the gauges yet.  advice?  gonna need to wind the pulse motor and generator coils.  what gauge do you want for pulse motor/generator?  im sure the pulse motor needs to be more windings of smaller gauge and generator less windings of thicker gauge.  correct?

Hi You really need to understand basics before you can understand what you are looking for and more so what you find along the way.

This is a good place to start.

Understanding how the coil and magnets interact is the key to these experiments.

perfect, i will get to reading...   thank you sir.
