A simple PC-Fan for Free Energy?
« on: June 27, 2009, 12:12:43 PM »
Hello,
I have see a picture of Bedini "Motor & Rewin-Generator" on the www.
I have now make a modify version of that.
You can see that in the attachment.
Can this "Motor & Rewin-Generator" supply electricity for endless, when
we change the Batteries after a time?
Is that a simple Unload and Load - System, or do this not work?

Very thanks!

@MKRoxton,

Here is how you can test your theory.

@ Groundloop,
very thanks for reply on my question!

Is the "7805" for Heatsink a voltage regulator?
I have only found a "L7805CV" with: 5 V and 1,5 A - can I use this?

Where is by the 12DC Fan plus and minus?

Very thanks!

Hello,

what do you mean with "remove electronic" by the 12 Volt DC Fan for use as generator?

Thanks!

@MKRoxton,

The 7805 is a voltage regulator. Since you will be using a 8,4 volt battery then
the +5 volt fan must have +5 volt. If you use a higher voltage then there is some
chance that the +5 volt fan will be faulty. (Eg. smoke.) L7805CV is OK for your +5 volt
fan. Use a piece of aluminium that have a size of 5 times the size of the regulator as
a heat sink. (Or any other heat sink you may have.) The +5 volt fan has two wires,
one red = plus and one black = minus.

All DC fans have a printed circuit board inside. They also have several (usually four)
spools of copper wire onto some soft iron stators. Inside the fan there is also a rubber
magnet and a metal ring. The printed circuit board (PCB) has some IC and other components.

So, the PCB is designed to get a DC volt INPUT to run the fan. To get the
fan to be a generator you need to open the fan and find the two points where the
coil is connected to the PCB. To open the fan you need to remove the sticker in the
bottom of the fan. Then you need to carefully ply off the small locking ring that
keep the axle secured. Then you can lift the fan off the stator. Now you can have
access to the stator coils and PCB. On most plastic fans it is possible to carefully
lift the PCB and stator coils OFF the fan metal housing. This way you can access
the underside of the PCB and solder two thin wires to the coil points. It may be
necessary to make small cuts in the PCB where the coils is connected to insulate
the coils from the electronic. If you do not do that the electronic may steal away
your power output.

There is no need to use a flywheel, as I see it. The easiest way to do it just to
center the smaller motor fan at the larger generator fan hub with glue. Just make sure
you have each hub centered to avoid vibrations. Then you just fix the stator of the
motor fan to the stator of your generator fan. Balsa wood or plastic will do fine.

These two wires will carry the alternating current when the fan is turned by your motor.
These wires can be connect any way to the diode bridge because it is AC.

The 7805 voltage regulator connects as the attached image.

I have added a Microsoft Word document that describe how you convert a PC DC FAN
to an AC generator. The document can be found here:

@MKRoxton,

I wanted a pc fan generator with a low voltage output so I changed the coils
to 0,2mm enameled copper wire, 60 turns on each of the four iron stators.
This gave me a little less than 2 volt AC when the fan was turned by the
air flow of my indoor cooling fan. One diode (by255) was used to change the
AC into pulsed DC. The Sunrise NiMeh battery (1600mA) did charge up very
well indeed. I think this prove that a normal PC fan can be converted to a
generator.

@ Groundloop

Hello,
hope I can built it and then show you the pictures.

Now, one question. When you see the attached picture, I don`t know how I
can connect the red and black cable, after cut electronic components.

Very thanks.

@MKRoxton,

Did you download and reed the doc paper i uploaded, found here:
http://www.overunity.com/index.php?action=downloads;sa=view;down=292

Turn the stator upside down and take a new picture for me. There should be two
solder points for the coil connection to the pcb. Just un-solder the black and red
wire and then solder the wires to the two coil points. Or you can remove the pcb
altogether and then solder the wires to the two coil points.

Groundloop.

@ Groundloop

I have make 3 pictures for you. You can load the attachment for show they.
How I now make connected the red and black cable? I have 4 coils and 3 Poles can show on electronic components.

@MKRoxton,

Solder off the red and black wire from the PCB and throw the pcb away.
Now look at the stator coils. Look where the wires are attached. Solder
your wires to the coils. Leave the center tap of the coils open.

If you have a Ohm meter (resistance meter) then find the two pins of the
stator coil that have the highest resistance and solder your two wires to
those two points.

Groundloop.

Dear Groundloop,
I have make here a new setup. Now I will use directly 2 Generators. But I don't know, how I must connect the cables of the second generator. I also don't know, if we need a voltage regulator or/and capacitors. In the attached picture you can se my plan. Can you make it finish for a possible rebuilt?

I don't know, if is possible use the equal output and input-power, why NiMH-Accus charge only right, when they are empty.They must also as first unload, before they can be charge right. I'am not secure if taht is right, but I have read this on any webpage.

Thanks!

@MKRoxton,

I have already explained to you how you can change a direct current
computer fan into an alternating current generator. May I suggest
that you first finish the first fan you started on and then test this
fan.

Where to go from there is up to you. I'm out of this thread.

Bye,
Groundloop.

Hello,
Have one here a idea, how I can make the axle?
And how I can make strictly on middle-point fix the axle?

Thanks!
