Answer / aayushi agarwal

1 phase motor is used in fans .. which is non self starting
.. so to mk it self starting we use capacitor start method
.. and so capacitor is used ... itzz an added advantage that
use of capacitor also improves the pf ...

Answer / tathagata

We use Capacitor in fan motor to shift the Phase difference
between two winding

Answer / m. b. shirsat

all the previous answers added together gives correct
answer. in three phase motor phases are already split and
produce resultant torque to rotate or start motor. Single
phase produce zero resultant torque and needs to split the
phase which is done by introducing capacitor in starting
winding.

Answer / aniruddh

Introdusing capacitor in ceiling fan motor to improve
starting torque with the effect of leading power factor to
make motor self starting.

Torque=Is*Im*COS@

Is=starting winding current.
Im=main winding current.
@=angle between Is&Im.

Answer / mahi&junu

to provide the leading power factor for the self starting

Answer / gopal bhagat

capacitor for in celing fan for reactive power
copansetion,power factor imrpovement and also helping for
starting torque and to set up rotating magnetic field as
self starting

Answer / essien victor

to produce a phase shift between the main winding and the
auxillary winding so that the motor can start on its own.

Answer / jibu tom

At the time of switching on the ceiling fan(without
capacitor),a pulsating flux is produced, which will not
help to revolve the fan and by using capacitor rotating
flux can be produced, which revolve the fan.

Answer / chandramohan.a

1.celing fan not self started so used capasitor
2.improve power factor
3.phase split

Answer / chirag bhatt

Capacitor is an energy storage device....so it stores the energy in terms of electric field.....and as we know the motor used in ceiling fan is not self starting....so capacitor is used to start this motor by the electric energy stored in as an electric field....

why should we have to maintain pf in our site 0.9????????
