Fan Basics: What is a Fan? - Continental Fan

Feb 18, 2019  A fan is a power-driven machine used to move a volume of gas. In other words, a fan is an air moving device. In its simplest form, a fan comprises a motor, a fan housing and a rotating impeller. A fan’s impeller design, its rotational speed, and the power supplied by its motor dictate the volume of air that the fan is capable of moving and ...

Axial fan design - Wikipedia

The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the number and shape of the blades. Fans have many applications including in wind tunnels and cooling towers. Design parameters include power, flow rate, pressure rise and efficiency.

Selection of direct drive fans (those with the motor shaft connected to the fan wheel or propeller) is nearly the same as belt drive selection. However, there are two differences worth noting. Where belt drive fan speed can be altered by adjusting the motor pulley, direct drive fans (since they have no pulleys) must use a different method.

Fan motor - definition and glossary

Fan motors are very simple in construction. They consist of a synchronous or asynchronous electric motor, with a fan wheel of the associated shaft, and the connections for the lines. However, DC motors are used (e.g. in computers or in a car). All motors consist of a stator and contain a rotating rotor inside, which is surrounded by pole-pieces.

Radial fans are industrial workhorses because of their high static pressures (upto 1400 mm WC) and ability to handle heavily contaminated airstreams. Because of their simple design, radial fans are well suited for high temperatures and medium blade tip speeds. Forward-curved fans are used in clean environments and operate at lower temperatures.

External rotor motor basics: Design and applications

Jun 06, 2018  Fan and blower applications are one of the more common uses for external rotor motors thanks to a specific design benefit: The external rotor can serve as the hub of the fan or blower impeller. This provides a compact package and allows the impeller to act as a large, rotating heat sink and assist with motor cooling.
