Fusionchip's Bedini Feedback to Source!!!

I re-tuned my fan to sound as close as possible to gadgetmall. My still runs a little bit faster but I think by the sound they are very similiar in the signal.

My battery is still the same voltage as 2 days ago.

Hmm. What do you think is going on there  ? ) you get em yet  ?

here are some pictures of the FAN.

The voltage is still the same and then fan is spinning at about 150 rpm very slow, lots of radiant spikes and the long wave pulse. The total  length of time for the radiant spikes (all of them) and the wave is exactly 1/2 for each so at one revolution we have 1/2 radiant and 1/2 wave with reciprocals.

I am very puzzled but this little baby

@hartberlin,

I did not change any of the widdings of this fan I only separated one of the poles that had two wires into two poles totaling 4 poles now.

Hi Fausto,
many thanks for the pictures.

I see, that these 48 Volts fans have very fine wire coils.
That is very interesting.
So they don´t have the big wire size normal 5 or 12 Volts fans have.

So this makes their inductance much higher and thus also the current going through them
much smaller, which is a good thing to save the batteries too much load current.

But now we still must know, which of the 4 coils you are using for the
primary and which for the secondary of your transformer in your circuit diagram ?

Did you put 2 in series for the primary and also 2 in series for the secondary ?
But which ones of the 4 coils ?

Many thanks in advance.

P.S. The sound wave sounds spooky !

good question Stefan, I have no idea how they are really connect, all I know is that there are 4 wires and each connected to one wire to the SSG circuit. I pretty much just tried all combinations until it worked. This is because only ONE combination will work all the others will simply either run current through the FAN and not spin or either the system will simply not spin at all.

I was wondering the same thing as you do. I assume by looking into those coils with magnifying glasses that they are simply 4 coils and one of them is a bifilar but seams to be connected as if it was a simple wind.

I also played first with the 12v fan and they were using the same size of wire as far as I can remember just much smaller winds.
