Ceiling fans are very basic. They have only two electrical componants: The motor, and whatever is used to control the motor. All other parts are mechanical or aesthetic. Motor turns blades, blades are pitched so they move air. What specifically are you interested in finding out?

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.

Huh, this question is four years old I would think it is resolved by now.

Please check the date. We try to avoid answering questions that are 6 months or older.

a ceiling fan works on the principle of electromagnetic induction which states that when a current carrying conductor is placed in a external magnetic field, it experiences a force.

A fan consists of stator and motor.

The motor rotates the blades of the fan by its rotation. for rotation it uses the force experienced due to magnetic field.

Therefore we need rotating magnetic field which is produced at stator by applying voltage at different phases.
But in ceiling fans at house hold purposes, we use single phase. so here the capacitor does the work of splitting(or shifting) the phase so that rotating magnetic field is produced.

Ceiling fan is a very common and usefull equipment for our daily life.
The basic principle of working of ceiling fan is electromagnetic induction.When we switch on the fan firstly current goes to stator and then it passes the current to runner coil.And after that it experiences magnetic field from flux generator.And fan starts rotating.As we know thatwhen current carring loop is placed in magnetic field it experiences force.In ceiling fan magnetic feild is created by flux generator.And flux generator is fitted in rotor.

hey guys i have a simple problem..

u said tat the capacitor just do the process of spliting the phases into two phases but my doubt is

a ceiling fan of ma home rotates at slow rate the electrician advised me to change the capacitor.. and then i too did accordingly and then my fan rotates faster,,,

may i know y it is so...
