A ceiling fan moves Counter clockwise & a pedestal fan
clockwise.....y the difference????
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.
