Dear user here your answer
The working principle of fan is based on double field revoving theory. According to this whenever we apply voltage to stator winding then its generate a pulshting type flux. Due to this there are two flux. First is rotating in clockwise direction and vice versa. And motor rotate in resultant direction.
As you tell that your fan is ten years old. So sparking is due to any fault in fan. But when you rotated it in opposite direction,its starting wind flux and running winding flux are opposes to each other.
