I Greg, et all.
The rotor has a mechanical switch that cut the power to the motor when it's in contact with the switch:
So stopped motor is ZERO Current...
About 450 and beyond...
You are right, but last days I was thinking/tweaking an algorithm that I think now will do the math..
I will code it in this next days... You will know about it...
73 and thanks for your tips/comments.

I forget... Do these kinds of motors change their current draw significantly when they stall? If they don't, a current probe may not be a reliable stop indicator.
Also, regarding the challenge with 450 degree rotation... There's no requirement that you actually use all 450 degrees. Just stick to 0-359 and it will make things a lot easier to start with. Once it's all running, you can go for the fancy stuff.
Good luck with the project,

The "motor running/motor stop" signal will be a current probe on the AC 24V motor feeding wires down the control, as when the motor reach 0o or 450o it automatically switch's off
