A fan motor rotates in the direction dictated by the type of blade it is using to move air in the desired direction. Both CW and CCW blades are used to do the same thing(move air in a particular direction). It simply depends on which type of blade one has in order to accomplish this and whichever blade you have will determine the direction of rotation of the motor driving it.

What could cause the compressor to come on but the fan to stop rotating on a central air conditioning unit?
Bad fan motor or bad capacitor.
A rotating fan blade has kinetic energy when rotating with constant angular velocity when the angular velocity is reduced to one third what will happen to the kinetic energy?
It will decrease by a factor 9.
A ceiling fan can rotate 150.26 times per minute. The fan rotated a total of 3756.50 times. Which of the following is true?
It had been rotating for 25 minutes
Why do large fan blades take LONGER time to stop rotating than shorter blades?
Because of larger momentum. Larger bodies have larger momentum.
Why is a 'Robot Sound' is heard in front of a fan?
Its because of the gaps between the blades of the fan. When a person speaks in front of a fan, the sound travels as usual but when it reaches the rotating blades, some of the sound goes through the gaps between the blades and some of it is reflected by the blades. So we hear the voice with gaps in it that sounds robotic
How do you use clockwise in a sentence?
The fan is rotating clockwise.
What is the 'flying ceiling' of a helicopter?
it is the small rotating "fan" in the back
Why does a rotating fan blade look like its stationary at times?
your eye can only see about 24 frames per second. so when a rotating fan rotates with 24 rounds per resond or 48 rounds per second and so on, your eye will take a "picture" of the fan at excatley the same spot. Your brain then put these immages after each other an you wil see a rotating fan witchs looks like it isn't rotating. I hope you understand my English;P and I hope this answer helps.
What is it that hits the fan in the idiom?
Excrement - it is "when the excrement hits the rotating propeller blades."
Is there is any workdone in fan when it is rotating and consuming electricity?
The work is done when the fan moves air, imparting kinetic energy to the air.
How ceiling fan convert electrical energy into mechanical energy?
The motor does it, by producing a rotating magnetic field, which twists the fan blades.
Why a fan is kept on rotating even after turning the switch off?
try a new switch
What could cause the compressor to come on but the fan to stop rotating on a central air conditioning unit?
Bad fan motor or bad capacitor.
A rotating fan blade has kinetic energy when rotating with constant angular velocity when the angular velocity is reduced to one third what will happen to the kinetic energy?
It will decrease by a factor 9.
Why ac fan moving onedirectiononly?
to save energy. if it alternated between the directions it needed more energy to stop rotating in one and start rotating in the other, while one direction only needs energy to keep rotating (not much).
What happens when the motor rpm is less than the fan rpm of an air handling unit?
To get the fan rotating faster than the motor driving it, gears are needed.
A ceiling fan can rotate 150.26 times per minute. The fan rotated a total of 3756.50 times?
It has then been rotating for 3756.50/150.26 = 25 minutes
