In generally capacitors are playing main role in electrical system.And also power factor improvement done by capacitors so therefore capacitors mainly using for increase the starting torque of the motor

IN SINGLE PHASE MOTORS CAPACITERS ARE USED TO SHIFT THE PHASE ANGLE TO GIVE A GERK TO START THE MOTORS.

Single phase induction motor does not have the ability to self start, hence to provide a phase difference of approx.90 degree, capacitor is used. Literally a single phase induction motor with a capacitor can be said as a two phase motor. Without using capacitor, you can provide starting torque by manually rotating.

Capacitors are used in induction motors to allow a phase difference and thus allow the motor to start. In general2 capacitors are used1 for start up and another for continuous use, due to the size of current required.
