Answer Posted / s.raghavendra
Basically to rotate an induction motor there should be some phase difference for the input excitation.For a three phase supply there is a phase shift of 120 degrees for each phase but in case of single phase there is no phase shifting . In order to produce a phase shift in single phase a capacitor is placed because a capacitor leads the current by some phase angle from voltage supplied which is the inherent property of a capacitor to charge and discharge itself , helps in creating a phase difference in single phase supply which starts the motor
