Hai Friends,
In this article I'll discuss about the working principle of a ceiling fan.
Every day after long hours of work we come home and relax under a ceiling fan. And do you know how does it work?
The answer I'm expecting is no.
Because if you know the answer there would be no reason for writing this article. Even if you know the answer just forget it for a while. Okay lets get into the topic.
Ceiling fans were first seen in Unites States and were invented by PHILIP DIEHL.
He had engineered the electric motor used in the first electrically powered single sewing machines, and in 1882 adapted that motor for ceiling-mounted fan.
In earlier days they didn't use the electric power to drive the blades of the ceiling fan. They used the stream of running water just as that of turbine. We may not see such type of fans now. But they are still being used in some parts of Unites States.
Now a days the ceiling fans contains 3 wings(blades) not like the older ones that contain 4 or 5 or even 2
WORKING PRINCIPLE:
It contains a capacitor that produces a starting torque and rotates the motor. And it also contains a number of windings.We know when a current carrying conductor is placed in a magnetic field produced by a coil when current is passed through it,it experiences force.
But the rotor needs rotating magnetic field. This can be done by applying different phases to different winding. But in our houses were we get only a single voltage face, it could be spilt into two with the help of the capacitor.
Actually the capacitor helps in phase shift(i.e a time offset between currents) and manner it look like a multi phase system. To spilt the phase there are also other methods but using a capacitor is inexpensive.
HOW DOES IT WORK:
Due to the inclined design of the blades of the ceiling fan it pushes the air downwards. Thus the air coming down and takes away the heat from our body surface and makes us feel cool, same as in case of engines in automobiles(i.e heat from the fins (that increase the surface area) is taken away by the air). And this hot air raises up as it becomes lighter and is forced to leave the room from the top.
These are the best cooling systems since they were invented as they consume very little amount of current and reduce the monthly bills. It's setup is very simple when compared to a typical AIR CONDITIONER.
And further several advancements are made by adding extra fitting likes Lights etc.,and remote controllers have also been developed other than speed control regulators.
Many creative designes have been made and you can just google them as Designer Ceiling Fans.
ANY QUERIES:
