The engine was the first element I tested to verify the feasibility of the project. After a little research to make a three-phase asynchronous motor work on an alternating current, I was able to verify that it turned correctly.
I made the conversion from three phase to single phase using a capacitor of 25µF 450V. connected between 2 motor coils:

The goal was to make a circuit quickly to develop the program with ESPhome and check if everything works as I wanted.

The aim now was to install the main components (limit switch, photoelectric sensor, etc...) and connect them as shown in the circuit above.

After correcting the main problems with the circuit and electronics in general, I set about designing an electrical board to make the portal's operation more reliable and, above all, more professional.
