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
