why we use capacitor in ceiling fan

                                        USE OF CAPACITOR IN A CEILING FAN

Fan mostly operates with a single phase induction motor. As it is not a self starting motor, it needs a rotating magnetic field to start. to two make it a self starting motor a condenser ( usually known as capacitor) is connected to it to give a starting push up , instead of external winding known as auxiliary winding. Single phase supply on stator of this motor  gives alternating magnetic field but we need rotating magnetic field, so we use condensers.  capacitors

are used to split the phase and make it operate like a multi phase motor , so that rotating magnetic field is developed and the motor becomes self starting.

So  capacitor start capacitor run motors are used mostly in ceiling  fans.
