Fusionchip's Bedini Feedback to Source!!!

[plengo]

I am having all sort of results on my experiments. Some good, some bad and some ugly.

Tunning has demonstrated to be very difficult in my 150 ohms per 2 widdings on the fan. I can run it in my best for days without any voltage drop but still no gain. Using SLAs on the exact same setup will in seconds loose voltage. Wet cell battery definitely plays an important part on the process.

Speed of fan is not that really important. I can run it very fast or very slow. What makes it important is the signal, lots of radiant spikes, with a long pause wave. That pause IS very important because it allows the battery to "receive" the spikes before output current again. The cap (C2 on previous schematics) will feed the fan while the battery "digests" the radiant.

Resistance of the fan will totally change the dynamics so I decided to use a trick. I doubled the voltage and re-tuned it. Just for the test now I am using an SLA (not good) with a wet lead acid in series totaling around 24+v. I have an excellent radiant spike above 200v before the first rotation is even completed. The spike is very scary actually. DO NOT TOUCH it at this source voltage level. Neither run this without the C2 cap.

Positioning two neo magnets in a specific location (one must find it) helps the spinning tremendously.

With this 24+v I am having excellent results so far. Soooo, lets wait another 3 days to see where the voltage will stand.

BTW, I am looking for a small wet cell lead acid battery that is around 2 to 5 amp/hour capacity to speed my tests. If anyone knows of a good site, please, let me know.

Fausto, have a look at UPS units, they contain 5 - 10 Ah lead acid mostly.
Another possibility might be lead acid battery for mopeds.

I was wondering if the principles of the "Time Energy Pump" could be implemented with these Bedini motors.

Perhaps use a 555 timer to run one of these bedini fan motors.


@Hartiberlin
Are you the same Stefan Hartmann that worked on the TEP?
If so what kind of results did you finally come up with?

Hi All,

Finally found a schematic (internal wiring diagram) for a brushless motor. Took apart my 12V  fan motor and tried to find out what the chip on my PC board was (an APX9140 hall sensor). Downloaded the data sheet and there was an application schematic (page 3)...which is the same wiring as on my motors' PC board, except mine doesn't have the capacitor. It also says that the capacitor is needed to eliminate high voltage spikes into Hall IC

Is this the wiring diagram that will work (bifilar windings)? Where would I tap into the coils to connect the fourth pin? I watched Imhoteps' videos but not sure where you tap into the coil for the fourth pin.

Here's the data sheet in pdf. Would be great if someone could re-draw the motor schematic with the necessary modifications.

Thanks!!

If you take a good look at the schematic taken from the pdf you posted, the fan coil is a Joule thief coil implemented on a fan.
