mostly because fans use induction motors therefore the starting torque is less,this is provided by the capacitor by increasing the voltage
There are usually two capacitors in a ceiling fan motor. One is the "start" capacitor and the other is the "run" capacitor. Simply put, an AC motor needs a rotating magnetic field in order turn the motor shaft. This is done by applying voltage with different phases to different windings. In a single phase system there is only one voltage phase. The capacitor is used to provide a phase shift in the windings of the motor, making it appear that the motor is operating in a multiphase system.
It will rotate faster.Since the fan is not designed for this, it will progressively ruin it.
by changing the polarity of capacitor of single phase ceiling fan can we change the direction of rotation from anticlockwise to clockwise
Due to the type of motor used in a fan. The capacitor provides a phase shift between the stationary winding and the rotating winding, which is necessary to get the desired torque.
There are a variety of capacitor sizes in ceiling fans. The capacitor is dependant upon the characteristics of the fans motor. Whether it is a single speed, two speed or three speed. If you think it is the capacitor at fault for the fan not operating, take the fan down and open it up. This will give you the exact sizing for your fan.See sources and related links below.
in a ceiling fan the capacitor is used to give the starting torque to motor for run. because we need a rotating type of magnetic field to the motor to run. once the motor run it become running even we disconnect the capacitor. by using the capacitor we produce the electrica difference(phase angle) between the two current taking by capacitor and the motor winding.

Electrolytic capacitors or film capacitors. The capacitor in an electric fan is used to start the motor, and the speed is controlled by the current of the governor. The size of the startup capacitor can only change the startup speed of the fan. Once the fan is started, that is, once the capacitor is discharged, the capacitor only plays the role of isolating DC. It will no longer participate in the operation of the fan. Because the capacitor only has the function of charging and discharging. ----We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.

capacitor?
Because of capacitor used in the fan due to its capacity to store the charge nad emmit the charge after fan is switched off.
The Capacitor with running winding is connected in parallel with main winding.
