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.
An axial box fan for cooling electrical equipment. Axial-flow fans have blades that force air to move parallel to the shaft about which the blades rotate. This type of fan is used in a wide variety of applications, ranging from small cooling fans for electronics to the giant fans used in cooling towers. Axial flow fans are applied in air ...
Elektrobau Mulfingen GmbH is the parent company of the ebm-papst Group, a manufacturer of electric motors and fans.The group was formed in 2003 from the merger of the companies Elektrobau Mulfingen GmbH & Co. KG (ebm), Papst Motoren GmbH and Motoren Ventilatoren Landshut GmbH and operates international production sites (including in Germany, China and the United States).

This plant manufactures Ventilation equipment, special electrical motors, axial and radial fans and accessories for agriculture, engineering, AC-equipment and cooling industry.
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
This instantaneous blade adjustment capability is an advantage that is possible with axial fans only. Cooling fans - (also referred to as "cooling tower fans") - These are axial fans, typically with large diameters, for low pressures and large volumes of airflow. Applications are in wet mechanical cooling towers, air-cooled steam condensers ...

Water-cooling radiator transfers a lot of heat, and radiator fans have large static pressure (opposed to case fans that have high airflow) for dissipating heat. Laptop computers lack large openings in the case for warm air to escape. The laptop may be placed on a cooler – somewhat like a tray with fans built in – to ensure adequate cooling.
