Ok, there is a picture of the motor i have. It is not the same, but very close:

It is working with capacitors and may be not good for servo, but i want to try at list.
remember that the main question now is about encoder strips. Im waiting for one answer on www.mercadolibre.com.ar to see for long encoder strips savaged from plotter machines. but the best goal should be to make it diy, and i´m breaking my head to see the way of doing that.
Thanks so far for the replies and keep it moving!!
