Fan

Fan is found in almost everyone house, its very much needed when temperature increase and humans feels hot especially during summer.

Fan working mechanism.

Electric fan works on the principle of conversion of electric enegry into mechanical energy and in this case mechanical energy is the rotarty motion. When AC is supplied to electric fan it first reaches capacitor. capactior sends high energy to the stator windings.

stator windings develops rotating magnetic field and which forces the rotor to rotate in the direction of magnetic field.

electrical energy is converted into mechanical energy, rotor and housing to spin and the blade attached to the housing throws away the air nearby and create cooling effect.

Parts of Fan

Capacitor : capacitor is used to store energy, this store energy is used to rotate the fan from rest state.

Axle: Axle is the metallic rod mostly made up of mild steel. Axle is connected from ceiling to fan housing 

Bearings: Ball bearings are used in the electric fan, 2 bearings which are link between housing and axle gives the rotary motion to the housing.

stator : stator windings is to convert electric current into magnetic field.

Rotar: Rotar in the electric motor is the permanent magnetic in the shape of half circles.

Housing: outer part or the electric fan.

Blades : Blades or wings used to rotate.

Future of electric fan.

Electric fan make use of 9% of residential energy, which is almost equal to power plant energy, so in future by using BLDC  technology  we can reduce use of energy by electric fan.

BLDC motor are more efficient.
