Three phases allows lower currents in the cables than a single-phase motor of the same power, and can run on three wires only, without the need for a neutral wire. There's no need for any 'syncing'. In a three-phase power system, the voltage between two phases is always the single phase to neutral voltage multiplied by the square root of three. https://www.raritan.com/landing/three-phase-power-explained
