+### Step 1: Check of the working existing components

+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:
