Answer / m awais

The capacitor is used to produce a phase shift to create a
rotating magnetic field so the motor will start turning.
3-phase motors do not need one because of the phase
difference inherent between the phases.

Answer / manoj

above both answers are right but i woulds like to add that
by increasing the phase diff the better rotating magnetic
field will be generated.
