A fan works by using an electric motor to rotate blades that push air forward. The motor contains a rotating shaft with angled blades attached. When the motor spins the shaft, the blades cut through the air at an angle, pushing it forward and creating a continuous flow of air that we feel as a breeze.
The electric motor is the heart of the fan. It consists of a stationary part called the stator with electromagnets, and a rotating part called the rotor. When electricity flows through the electromagnets, they create magnetic fields that cause the rotor to spin. The shaft connected to the rotor transfers this rotation to the fan blades.
The blade design is crucial for creating airflow. Each blade has an angled, curved shape that cuts through the air efficiently. As the blade moves, it creates a pressure difference - higher pressure on the back side pushes air forward, while lower pressure on the front side helps pull air along. The curved shape and angle direct the airflow in the desired direction.
To summarize how a fan works: An electric motor converts electrical energy into rotational motion. The angled blades create pressure differences that move air forward. This continuous rotation produces steady airflow for cooling, using a simple yet effective design found in many applications.

Here's how a complete fan operates: First, electricity powers the motor. The motor then rotates the central shaft. The fan blades, attached to this shaft, spin along with it. As the angled blades move through the air, they push it forward, creating a continuous stream of airflow that provides cooling and ventilation.
