Oh my coil! ;-)

Thanx for the reply, Peter almighty. I thought on using the two transistor's for each coil and I'll do that in my next experiment for sure. I just wanted to try all this in very little time I had.
The dots on the coils, I used them to indicate that the poles are oposite on the electromagnets because it works better like that. I also tried to put these in series and it worked also ok and it draw about 45mA but the RPM is lower in that case and the torque as well. And it was also stalled by connecting the battery.
Whatever the case is, parallel or series configuration, the motor definitly works better when I have one N pole and one S pole towards the iron like on the picture.
The most important thing for me is that the motor works, and I am always seeing the SPIKES on the scope!
Also I need to make some of the FE machines so that I can persuade my father to begin research with me, he is great physics professor but he's been a bit sceptical about all that, but I think he is on his way!
I'll post the news as my experiments continue in a few days I hope.

Thanx again and forgive me for my bad English. Respect!
