Standalone fans are usually powered by an electric motors, often attached directly to the motor’s output, with no gears or belts. The motor is either hidden in the fan’s center hub or extends behind it.
In machines with a rotating part, the fan is often connected to it rather than being powered separately. This is commonly seen in motor vehicles, where the fan is connected to the drive shaft or through a belt and pulleys. Another common configuration is a dual-shaft motor, where one end of the shaft drives a mechanism, while the other has a fan mounted on it to cool the motor itself.
