Why celling fan
rotates in
anticlockwise
direction and
table fan in
clockwise
direction ? Give
technical reason.
Answer Posted / sathish
In earlier days, the ceiling fan is very heavy and down rod pipe is connected with fan through threaded coupling and chuck nuts. When the ceiling fan starts rotating in anti clock wise direction the armature winding part take jerk in clock wise direction. This clock wise movement helps to prevent the joint getting loosen. Hence the ceiling fan designed to rotate in anti clock wise direction.
