There seems to be lot of misunderstanding and misinforming factors) concerning the instructions of turning of ceiling fans and table fans remaining in opposite instructions.
As a matter of fact in a lot of the relevant literature, the term 'motor' itself has actually been wrongly used as well as any type of practically experienced person can make out this.
Technically, both types of electric motors work based on the concept of a single phase induction electric motor. A single stage motor has a stationary pair of windings (in what is called a stator) positioned in quadrature with each various other and also created to bring currents with a phase distinction of 90 degrees preferably, from a solitary phase AC supply.
The various other component of the induction electric motor is the rotor, the turning component which can be stated to be a number of conductors in which currents are induced. The currents coming on the stator windings create an electromagnetic field, say revolving clockwise. The further chain of electric events make the rotor comply with the magnetic field as if to catch it. i.e, the blades runs clockwise also. If a button is provided to reverse the instructions of current in among the stator winding, the magnetic field as well as thus the blades runs in the anticlockwise direction.
In a ceiling follower, the stator with its winding is enclosed by the rotor to which the follower blades are attached. A ceiling fan is installed near the ceiling so that depending upon the direction of rotation, it can push air downstream (normal usage as a fan) or it may be utilized to suck cozy air upwards (as in winter season, specifically in cool nations) by reversing
the direction of rotation making use of a control switch.
The direction being clockwise or anticlockwise is loved one. Looking from below, if the ceiling follower runs in an anticlockwise instructions, looking from the ceiling, it is clockwise.
Really, there seems to be an interesting background for this convention (Sujit K. Biswas, Jadavpur University,4 th Apr, 2014, ResearchGate|Share and find research).
When DC electric motors were being made use of earlier to Air Conditioner motors, the commutator as well as brushes of the DC motor were positioned in the direction of the ceiling for factors of ease of access.
as well as maintenance. Most significantly, with this established, the Dc electric motor was running in a clockwise instructions from the commutator end (ceiling end) in keeping with the right-hand man screw convention, faucet turning direction to stop water circulation etc. Place in easy terms, a person on the floor would certainly observe an anticlockwise instructions. This convention has been preserved even after DC motors were changed by Air Conditioner electric motors.
Practically every little thing about the ceiling fan is true with a table follower, practically. Nevertheless, it is claimed that as opposed to the commutator side dealing with the vertical wall surface behind (ala ceiling for a ceiling fan), for factors of beauty, it was turned around, as if to deal with the onlooker ahead. This transformed the instructions of turning from the viewer's point of view, to the clockwise instructions. Even after the replacement of DC electric motors by Air Conditioning electric motors, the very same convention is still being followed.
An Air Conditioning motor, unlike a DC motor, is a mechanically in proportion electric motor considering its major working parts as well as either end can be made to be the user end (such as blades in a fan) by ideal mechanical style. In theory, therefore, a table fan can be made just with ideal mechanical style to run anticlockwise.
Electrically, both ceiling and table followers are similar (Both have stationary windings getting AC supply and both have a blades for induction of currents as well as induction electric motor activity and also do not add to the difference in directions.
