A ceiling fan is a complicated piece of machinery. The main
components are:


An electric motor
Up to six paddles referred to as blades
Metal arms or blade irons connecting the blades to the
motor
FlywheelRotor, an alternative to the blade irons
Mounting mechanism

Motor used is a single phase induction motor.In order to
self start it an auxillary winding is connected along with
a capacitor, so that a phase difference is created and thus
the torque could be produced.
