Question

why does table fan rotates in closewise direction but ceiling fan rotates in anticlockwise ? with explanation

Answer 1

celling fan and table fan booth rotates clockwise direction table fan refrence consider table but celling fan consider roof of the refrence then you ask anticlockwise when you take celling is refrence then you say clockwise direction ..got it?

or u can say this depends on how the fan blades were designed or angled. The rotation direction is not that important, because combined with how the blades are angled, then you would get air motion (wind) going forwards away from the fan. Most ceiling fans actually have a switch which will change their rotation direction. It depends if you want the fan to BLOW wind down (spins one way), or **** air up (spins the opposite way). In most 'science classrooms' the fans sometimes are sucking air up so as to draw gas fumes away

Answer 2

This is mainly because of the diversity in their working principles. Every fan needs a motor that allows rotational motion. Taking into consideration the structure of a motor, there are two major parts - The motor itself and the armature. Out of these two parts, one part is always stationary while the other moves around it's axis allowing rotation of any object that is attached to it. Ceiling fans have a stationary armature and the motor moves in the counter-clockwise direction. Since, the blades of the fan are attached to the motor, the ceiling fan rotates in an anti-clockwise direction. It is exactly opposite for a table fan. The motor is stationary and the armature moves to give motion to the fan blades. Because of Newton's 3rd law of motion that states - "Every action has an equal and opposite reaction.", the stationary motor gives the armature a push in the opposite direction. This causes the blades of the table fan that are attached to the armature, to move in clockwise direction
