Ceiling fan is a Single phase Induction motor. Generally we use a capacitor start &Run AC Motor for ceiling Fans.
Motor principle: whenever current carrying conductor is placed in a magnetic field-it experiences force.
Stator: supplied by 1-phase voltage, current will produce in the stator winding-so magnetic field. But AC motor needs a rotating magnetic field in order turn the motor shaft (fan blades). This is done by applying voltage with different phases to different windings. In a single phase system (like at your house where you would use a ceiling fan) there is only one voltage phase. The capacitor is used to provide a phase shift (i.e. a time offset between currents) in the windings of the motor, making it appear that the motor is operating in a multiphase system.In Simple Terms, A single Phase is Split Into Two. There are also other methods to split Phase But using a capacitor is less expensive.
Now we have magnetic field.
We need current carrying conductor:
Because of Induction, voltage will develop in rotor as It is a closed circuit current will produce-so current carrying conductor placed in magnetic field.
Rotor will rotate.
