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. 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: I made the conversion from three phase to single phase using a capacitor of 25µF 450V. connected between 2 motor coils:
