Before electric fans were available, people relied on manual fanning – and it was a tiring job. Today, electric fans are everywhere – in homes, offices, and cars. Some are built into the cooling system of air-conditioning systems while others adorn the ceiling (ceiling fans).
A simple electric fan works on a basic principle: electricity is converted to mechanical energy that spins the blades. The electrical energy passes through the fan motor windings, stator and rotor, which are connected to a shaft bearing assembly on the inside of the housing, and the outer fan blades. The shaft bearings provide rotary motion to the blades, which in turn produce the wind that cools you down or blows away dust and other particles in the room.
Desk and pedestal fans are portable and offer multiple settings, including oscillation, while tower fans provide the most powerful airflow. Often, they come with remote controls and adjustable tilt to direct the airflow. For the ultimate in quiet and efficiency, look for smart models that allow you to set a timer or adjust the temperature from anywhere in your home.
For your car, an electric radiator fan mounts directly to the factory fan shroud or radiator and eliminates the belt-driven fan on the accessory/water pump shaft. This helps improve horsepower and torque by reducing the engine drag caused by the factory fan. Adding a battery-powered fan can also help keep your radiator and water pump cool after the engine has been shut off. electric fans
