Answer Posted / raseelrasheed

ANSWER IS SIMPLE....FAN IS A SINGLE PHASE INDUCTION
MOTOR....EVERY MOTOR HAVE FIELD AND ARMATURE,FIELD AND
ARMATURE ARE OPPOSING IN NATURE,SO FIELD TEND TO ROTATE
CLOCKWISE WHERE ARMATURE TEND TO ROTATE IN ANTI-CLKWISE.

IN CEILING FAN FIELD IS TAKEN AS STATIONARY AND ARMATURE
ALOWED TO ROTATE,SO ITS ROTATION IN ANTI CLKWISE,HENCE LEAF
CONNECTED TO ARMATURE IT ROTATE IN ANTI-LOCKWISE.

WHERE IN PEDESTRAL FAN,ARMATURE IS TAKEN AS FIELD ROTATING
AND ARMATURE STATIONARY,HENCE LEAF CONNECTED TO FIELD IT
ROTATE IN CLOCKWISE.
