new here! several questions

[sumhungl0]

i have been away from generators and electronics for quite a while but would like to read more about overunity.  i have been an aircraft mechanic for most of my life and learned all about generators and electrical theory, however i have a desk job for the past 5 years and it has been 15 since i went to school for it. i need some refreshing of some things.

enough about me, on with the questions....

when winding a generator coil, i cant remember what creates voltage and current.  is it the bigger the coil wire gauge, the more current it can carry and produce?  and the more windings, the higher voltage?

i have worked on motor generators for powering radar and other aircraft equipment that would take utility power to run the motor but on the same shaft has a generator that produced way more power then what was consumed.  there was no back feeding of power to the motor or charging of batteries for any type of self powering, but i do not see why it could not work.  for the average persons home, why cant something like this work?  why not have a power unit in every home?  i was not thinking that way 15-20 years ago but i sure am now....

what about generator speed/rpm?  every generator ive seen has to be running at high rpm.  what would the coil windings be like for a slower rpm?  is it possable or would you lose production of power?  or would you just make the flywheel/rotor bigger to accommodate more magnets/coils thus giving more pulses for the reduction in rpm?

i have watched everything i could find on youtube so much i think its time to start asking some questions.  any feedback is greatly appreciated.  happy holidays.

If memory serves me correctly you are right, fatter wire = more amps and longer wire = more voltage

       Generally, yes.   Heavier, larger diameter wire will carry more current.   A bigger-diameter wire has less resistance per foot of length.   Longer lengths of wire mean more resistance in proportion to the length.   Twice the length means twice the resistance.   BUT, in a transformer, more turns in a coil, will give you more voltage compared to the turns ratio between the input to the output.

  Well, I saw a diagram of a motor that spun a generator---that went to a bigger motor to a bigger generator, and so on.   That's what I saw.   I never had the time or money to test this scenario.  As it is the way I described it here, I don't know if the theory is sound or not.

what about generator speed/rpm?  every generator ive seen has to be running at high rpm.  what would the coil windings be like for a slower rpm?  is it possable(possible) or would you lose production of power?

  Generators are sized to the motor that powers it, now that I recall.   A generator usually has about 95% the power rating of the motor, on purpose.

"or would you just make the flywheel/rotor bigger to accommodate more magnets/coils thus giving more pulses for the reduction in rpm?"

       A flywheel can increase average efficiency, but, AFAIK, you can't get overunity using this scheme of operation.

"i have watched everything i could find on youtube so much i think its time to start asking some questions.  any feedback is greatly appreciated.  happy holidays."

       Sure.   Always glad to try and help.   Read what I wrote and see if it makes sense to you.   More questions?   Sure, just ask.
p.s.
       All I wrote was taken from my personal memory.   I'm 66, now.   And I have a genetic condition that can lead to advancing  memory loss.   Honest suggestions and constructive advice is welcome.

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.

didnt know anyone was on here, anything is better then nuttin...

correct sm0ky2.
same device, same shaft.  and that is what i would like to build, but in the form of a low power pulse motor that has more then enough torque to run a generator(same shaft/device) and also be able to run something mechanically off the shaft.  well if needed.  maybe im asking too much. 

so i started messing around and im trying to do some simple testing/build of a pulse motor, small scale.  four half inch neos from old hard drives hot glued to a cd.  using an old cd drive motor and cd holder as a bearing, motor is shot but makes perfect rotation.  reed switch from here. http://www.allelectronics.com/make-a-store/item/rsw-40/spdt-reed-switch/1.html also got a few old coils from toys and such.  tried a few self wound coils as well.  cant get anything to push this past the point of me spinning the disc.  tried different power supplies, 9v battery, 9v/150mA adapter reading 14v output and few AA batteries in series. 

the adapter has enough power to attract the magnets but not very well.  but it also makes the reed switch arc so much that it sticks closed or welds itself together.  what do i do to fix that?  do i need a cap or resistor to help cut down the switch current?  i even made my own reed switch but still same result.  metallic metal from a pipe cleaner attracted to the magnets from the disc and rests against copper wire. 

any help with that would be great?

other then that, thanks everyone for the useful info.  any more advice would be great. 

gonna start ordering parts for a build hopefully this summer.  spools of copper magnet wire are kinda expensive and i wanted to get a few different gauges.  those neo magnets are not cheap either.  anyway, hope to order sum of this stuff soon.

thanks again for answering my questions.
