Ceiling Fans run on single phase supply, We use two capacitors in these fans and they are named as
Start Capacitor and Run Capacitor
To run the motor shaft (or the fan blades) a rotating magnetic field is needed.
To do this different phases are needed to be applied to different winding in order to run the motor and since there is a single phase supply hence these capacitors are used to provide a phase shift to the supply virtually making it working on a multiphase system.
This is the purpose of using capacitors in Ceiling Fans or single phase motors.
