I saw today in the electronic shop, that they also had 230 Volts AC types fans.

How do these fans work ?
Is there a little synchron or ansynchron motor integrated ?
Do they have any usefull coils in them ?

I did not yet google them...

Thanks gadgetmall

There were 2 wires gold and red so I had to solder extension wires and made them yellow for the gold colored wires and green for the red wires (see pic below).

Notice that the wires have been soldered together to extend them, in the picture that I posted previously you could see that there were 2 short wires and 2 longer wires, now you can see in the picture that there is no shrink tube on the 2 shorter ones because they are under the back casing.

So tomorrow I will hook up the 2 yellow wires onto the primary side and the red on the secondary of your circuit if I can get a hold of the components that I'm missing.

Ok . glad you got it apart . check the continuity on the two sets of wire . solder for the 4th wire so you have 4 post and two circuits . should work fine.It appears to have two windings because it has two colors of wire therefor its bifilar.

Edit:  Here's the specs on the fan, Hartiberlin this fan comes from your neck of the woods 

EBM W2G110-AM41-92
48V -(36-56V) DC
5,9W 3100U/min
= rot -shwarz
Made in Germany 12/93

Thanks,

Hi . I dont know . As far as the Brushless dc fans there is a complicated circuit to make the Dc switch polarity on the two windings that make the  fan spin due to the ring magnet in the rotor .. Funny they waste all those components when they could just use one transistor  I want to convert a large window fan . I assume that they will have their coils out of phase like these and because they use an ac electromagnetic field there is also some sort of  Magnetic rotor in there as well .(I hope ) we will find out Cause i am looking one . And the big Blades will make a perfect flywheel effect . Could even add lead to the outer egdes to get more Fly out of it ..

Ok paul . remember if it dosn't spin reverse the trigger wires !

Just an update. I have the Fan running with the new transistor TIP32A and the new diodes SK3606. The battery has the same voltage as 5 days ago and it is spinning at about 118 rpm. I think current is around 7ma. I dont really know because I had to remove the meter so that I can tune it properly (the meter turns off automatically changing the whole tunning).

I am happy with it except that my battery is not charging up (which is my goal). It is running but too early still to judge by the size of the battery, 100 amp/h little beast.

Soon I will have pictures and videos.

Fausto.
