I tested the rotor inside of the original motor and it worked.
The output at the charging diode was 1.5 volts less than the test
performed with the original rotor today.

I tried the joule thief configuration on the original motor and it does not work at all.

Conclusion:
To get the new motor working, it needs more copper windings than the original one in order to get the same amount of output.

By the way. The output today of the original motor with the lt1073 chip
to get 12v was just 4.5v.

The new motor 3v.

The model to make the joule thief motor was this one:
I dont hnow who the author was.

I did the windings just like that and failed.

Jesus,

One easy way to make a good motor is by using a computer fan.
(Bigger is better.) You remove the fan blades from the hub.
You also remove the electronic inside the hub so that you
end up with a nice little rotor with bearings. Then you glue
Neo magnets to the outside of the Hub, say four Neos
alternating NSNS. Use strong glue and secure the magnets
with some strong tape all the way around the hub. You now
have a good rotor with magnets. Find a plastic bottle that has
a diameter a little larger than your rotor. Cut a ring out of
the plastic to make coils on. Orientate the coils 90 degrees
to the rotor spinning direction.

Thank you @groundloop!!!

That is a very simple way of making a motor.

Even though I have not been able to get the same behaviour from the motor I had that used to work from one 1.2v battery and when feeded back the energy produced on the coils to the 1.2 or 1.5v battery by just touching the positive of the battery with the wire coming from the output diode, it used to recharge inmediately.

At least I learnt a lot about pic programming.
Thanks be given to all the people that contributed one way or another on this topic.

Thank you all.
