How do Fans work? 06/10/16
“How do the fans in our everyday lives work?”
Have you ever wondered how does a fan work? You might be surprised to find out that the operation is surprisingly very simple. A fan is primarily powered by an electrical motor. Attached to this motor are rotors. When the motor spins, the rotors will create a pressure difference in the air which in turn creates wind. Fans often have casing around them to simultaneously protect the rotors from exterior damage and to direct the wind flow. You can think of a fan almost like the reverse wind turbine, with a motor using energy creating wind in the air instead of wind creating energy in a generator.
