I understand that if a 3-phase motor is running and loses a phase it will continue to run at elevated current until the overloads (if they are sized correctly) will shut it down.
If the single phasing issue is NOT corrected and the overloads are still good the motor will not start when energized.
My question is if you turn the shaft to get the rotor spinning will the motor then pick up and run while single-phased? My thiinking is that by turning the motor shaft you are manually creating the field required for rotation.
Your thoughts please.
