Welcome to
The 3-phase motor would not have had a neutral at the motor. You will have to add a neutral from the electrical panel, routed through the motor starter to follow the phase conductor.
Make sure you have 120 volt to neutral on tbe phase/line input you would use for the single-phase motor. The overload protection will have to be sized ro the load of the new single-phase motor.
