Fan death is a misconception that people have died as a result of running an electric fan in a closed room with no open windows. While the supposed mechanics of fan death are impossible given how electric fans operate, belief in fan death persisted to the mid-2000s in South Korea , [ 1 ] [ 2 ] [ 3 ] and also to a lesser extent in Japan .
Electric Fan (Feel It Motherfuckers): Only Unclaimed Item from the Stephen Earabino Estate is a 1997 work of art by John S. Boskovich.The piece consists of a functioning electric box fan, the only possession Boskovich was able to keep that belonged to his partner, Stephen Earabino, following his death in 1995.
The motor is either hidden in the fan's center hub or extends behind it. For big industrial fans, three-phase asynchronous motors are commonly used, may be placed near the fan, and drive it through a belt and pulleys. Smaller fans are often powered by shaded pole AC motors, or brushed or brushless DC motors. AC-powered fans usually use mains ...

A standard cooling fan is a DC motor with blades attached. By varying the voltage input across the acceptable range for a fan, the speed of the fan will increase (to added voltage) and decrease (to reduced voltage); a faster fan means more air moved and thus a higher heat exchange rate.

An internal fan-cooled electric motor (colloquially, fan-cooled motor) is a self cooling electric motor.Fan cooled motors feature an axial fan attached to the rotor of the motor (usually on the opposite end as the output shaft) that spins with the motor, providing increased airflow to the motor's internal and external parts which aids in cooling.
Brushed DC motors were invented in the 20th century and are still common. Brushless DC motors were made possible by the development of solid state electronics in the 1960s. [4] An electric motor develops torque by keeping the magnetic fields of the rotor (the rotating part of the machine) and the stator (the fixed part of the machine) misaligned.
