Nix-

If you are rectifying the output of the generator and feeding it to the motor, you should get more voltage and the motor should go faster as the generator goes faster, assuming the motor is a DC motor. You would have pretty ugly DC but it should get the job done.

I'm not sure what application this is for,
just a thought exercise,
but if the generator was DC,
no rectification would be necessary?
Thanks mate for letting me know it might work.

The rotating field of a generator produces AC, if you rectify it you can get something near DC with it, and even closer to DC if you filter it, usually by putting a large capacitor on it. Be careful if you mess around with any sort of home made generator as collapsing magnetic fields can produce high voltages if there is no load or regulation. I think you can get generators that already have the rectifying and regulation built into them. That's pretty much how the alternator in an automobile works.

Thanks mate,
I just tried it,
and am getting a stable dc .5 v generation from a 2 1.5v batteries.
I didn't do the diodes thing, I only have 1.
My multimeter is telling me it's a stable .5 volts?

I'm not sure I'm following what you are doing. I was thinking you were going to use a generator turned by some sort of mechanical means to generate voltage to run a DC motor.

I wrote this to a guy who builds analog synths->

The essential idea with schematic is,
the motor and generator are coupled, and run conjunctively,
with electron flow blocked to the generator by the diodes.
A current is applied, and continues to be applied.
The power supply is augmented by the generation,
so it sums.
When power sums, more is available to the motor.
This in turn excites the generator an increment,
which is fed back through the diodes.
So it's like an electronic feedback loop sorta.
I'm hoping this is a decent concept,
called additive generation.


Briant'72, I am going to get some diodes tomorrow and try this.
I will use tiny motors, so I will break the circuit if anything gets too hot.

basicly you are going to build a qmogen! some folk claim to have them self sustaining in a closed loop, You will need to rectify the ac produced by your generator before feeding it back to your motor nix! you can make a FWBR from 4 diodes and you can smooth out the generated signal with some caps! good luck!

oh and btw! electrons do not flow ;)

IMO electricity is electron exchange,
I may be wrong though.
Maybe it only affects the next particle orbit.

If this works I am going to call it the summing generator,
or additive generation, not QmoGen

I have tried two different pairs of DC motors now,
and both generate DC.
They show a steady DC figure on my multimeter.
One pair had an efficiency of 16%, and the other 50%.

I really don't want to build a sub-par rectifier.

The schematic has changed in that there are now 4 diodes.
The battery requires diodes too, otherwise if the device works,
it will charge it.

Thanks for the info on the device name,
now Googling is on

Cheers fellas

I had an instructor back in the day (too long ago) that liked to argue with himself about electron flow versus 'hole flow'. He was an interesting guy.

I'm not sure something like this could sustain itself for any longer than just the motor on the battery alone. You lose energy due to friction, the diodes, magnetic coupling, and I'm sure other things I don't understand. I wish you luck though. It will at least be an educational experience so enjoy.
