Is DC single-phase or 3-phase?

Are 3-phase motors AC or DC?
Answer : 3-phase motors are **AC (Alternating Current)** motors. They are powered by a 3-phase AC supply, where the voltage alternates in three separate phases, creating a smooth and ... external starting mechanisms, unlike DC motors that require a separate power supply to generate direct current....
