New youtube of magnet/coil "perpetual motion"

[pinestone]

I think you guys have missed the simplicity of this thing.

Hi, What transistor(s) would you recommend? Describe the coil/core diameter/lenght. Bifiliar AWG Wire size/ lenght.---- All as starting recommendations --- Working voltage of the cap also.
Input on just what small DC fan motor might be used would also be helpfull.  Operating voltage/manufacturer ??

I would like to build this and give it a try.

This is just a concept type drawing. I really haven't thought about actual values.

But:
You may want to experiment with 600 - 700 turns of #32 magnet wire on a core made from 1/16" welding rod (iron). cut the rods about 1 1/2 " long and hold them together with a piece of shrink tubing. Hold the whole thing together with a few drops of superglue.
I've tried bi-filar wound and separate wound (on the same core) coils. I really didn't notice much of a difference. I doubt you need such a high impedance on the secondary coil to fire the transistor, so you could get away with a secondary coil on the same core, using less turns (instead on bi-filar wound).
Since the cap is storing the energy for the next stage, a big value like 1000 uF or higher would be a good choice.

A motor out of an old inkjet printer or tape player would work as a dc generator.

Even though I drew a bi-polar transistor in the diagram, a power MOSFET would be the best choice. Something like a IRF521 or equiv.

Pinestone,

Am I correct in thinking that the iron core suggested is made up of smaller 1/16 inch iron rods bundle/stacked together and 1.5 inches in LENGHT ? I have many of those. If that is the case what might be the core bundle DIAMETER? The rotor magnets will face the core diameter.
Need both figures as starter recomendations.  Do you think ultra fast switching 1N4148 diodes will work?  I would like to stay away from anything that needs battery power so what other transistors might I try?  A 2N2222, 2N4401, and a 2N1711 have been suggested??

I dont care if I reach overunity but coming real close will be nice if thats even possible at all.

My experiments have shown the coil core diameter should be equal to the magnets diameter for the best performance.  Using iron rods in this arrangement is similar to a laminated core (like a screen door for electrons...ha ha).
A FET transistor would be a better choice for the coil driver- fast switching with low loss.
As for the diode, any general purpose switching diode should work.

Like I said earlier, this is just a 'thought experiment', and I've never actually tried to build one, but I've made quite a few Bedini, Adams and other similar types of motors successfully.

Little DC motors will generate electricity, but finding the best motor for this type of application may take some digging- plus the correct ratio between the rotor diameter and the generator (motor) output will be tricky to figure out.

The biggest problem I see with ANY attempt at overunity is when a real load is put on the device, there will not be enough power to keep going. It may run itself, but that would be like a dog chasing its tail-

good luck

BTW, in my original description, I said the dc generator (motor) will spin 4-5 times faster than the outer magnets, but what I mean is there will be 4-5 more times the TORQUE on the generator (motor) than the outside of the rotor. My bad.

Hi,
Thanks for answering my questions. I appreciated the advice.

Now can anyone suggest a small DC motor that spins at a low speed when used as a motor.  Also might generate 2 volts DC or more at a lower speed without using much force  to turn the drive shaft. (What transistor triggers at 2 volts?)  I see Surplus Sales of Nebraska has many smaller DC motors listed. I searched Ebay also.   Which one might work for this aplication?  Any guesses??? 

The whole setup should not drain anyones wallet or cause financial ruin. So what the heck--I for one will try and I am not an electronic guru.

Say I used an aluminum bike wheel with powerful neo disk magnets spaced evenly all around its outside diameter. The wheel would be balanced perfectly and ride on a bearing that is almost friction free.
A 6 volt bike light generator would be mounted to the wheel  and its power directed into the illustrated circuit.--- Would that work if the generator drag was not that great?
