capacitor is for startin purpose

Answer / dipen dalsaniya

Domestic fan has to winding one starting and other one
running wdg.so capacitor used to for the purpose of
starting.

Answer / sanjay dalvi

to genrate rotating field in single phase motor Capacitor
is used as a starting winding;when motor rotates at 80 % of
full speed ;Starting winding cut off from circuit & fan
motor runs at rated speed.

Answer / dilli babu

fan is a capacitor start and capacitor run motor.
Basically single phase induction motor is not a self start motor. Fan having starting coil and running coil. The capacitor is connected to starting coil. when we are giving supply to the fan, because of the capacitor charging and discharging charector the current flows through the starting coil and capacitor and it starts rotation.

Answer / smita

In Domestic Fan working, it consistes of an induction motor
for fan rotation, and capacitor is used for power factor
control.

I BOUGHT A HAVELLS ACCL WITH GENERATOR STOP FASCILITY(i.e- BASICALLY IT IS A AUTO CHANGE OVER SWITCH) FOR MY HONDA EXK 2000S HOME GENERATOR (WHICH START IN PETROL & RUN IN KEROSENE). ACCL HAS 8 POINT. 2 FOR MAINS(PH & NUE), 2 FOR LOAD, 2 FOR GEN AND 2 FOR IGNITION POINT(X1 & X2). THE IGNITION POINT IS SPECIALLY FOR AUTO ENGINE STOP WHEN MAINS POWER RESTORE. I CONNECT THIS X1 & X2 POINT TO THE GENERATOR STATER MOTOR & EARTHING POINT. BUT WHEN MAINS FAILS THE GENERATOR COULD NOT START, BUT WHEN DISCONNECT THOSE X1 OR X2 POINT, THEN THE GENERATOR START. BUT WHEN MAINS ON THEN THE GENERATOR SHOULD START, AND WHEN I OFF THE MAINS THE GENERATOR AUTOMATICALLY STOP. PLESE HELP ME HOW I STOP THE GENERATOR AUTOMATICALLY WHEN THE MAINS RESTORE.
