A fan is a motorized machine used to create an air flow. The fan consists of an arrangement of rotating blades. The entire rotating blade is known as a wheel, rotor, or wheel. Usually it is included in a package or box. Fans are used to circulate air through rooms and buildings to cool them, and when current passes through the wire, a magnetic field is produced which exerts a force in a clockwise motion. watch who converts electrical energy into mechanical energy. This action rotates the motor windings. As the coils rotate, the fan picks up this rotational movement and transfers it to the fan blades.
