Answer Posted / 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.
