The structure of an AC fan, often referred to as an AC fan, consists mainly of the fan blades, rotor, stator, fan frame, and bearing system, which work together to fulfill the function of the fan. While the basic components of an AC fan are the same, the advantages and disadvantages of DC fans and AC fans are different, with the AC fan being one of the most active components.
The main body of the AC fan is the stator, and the components of the stator include the motor, outer frame, bearings, grommets, springs, upper cover, silicon steel sheet, lower cover, and circuit board. The function of the stator is to provide power for the fan and drive the rotation of the fan through the rotation of the motor. The motor of the stator is usually an AC motor, which is characterized by high efficiency, stability and low noise to meet the use of the fan.
The rotor of an AC fan is composed of fan blades, shaft center, magnetic ring, magnetic ring outer frame, and oil ring and other components. The role of the rotor is to convert the power provided by the stator into wind power, and through the rotation of the fan blade, the air is sucked in from the inlet of the fan and then discharged from the outlet. Most of the fan blades have an odd number and the curvature of the blades is slightly curved to ensure that the airflow is concentrated.
The fan frame of an AC fan is a whole composed of fan blades, rotor, stator and other components, its role is to support and fix these components, but also play a protective role to prevent the fan from being damaged during use. The fan frame is usually made of metal material for high strength and durability.
The bearing system of an AC fan is made up of bearings, bushings, tiles and other components, which serve to support the rotation of the rotor and also serve to reduce friction and noise. The life of bearings is usually 50,000 hours, and the life of oiled bearings is 250,000 hours, so regular replacement of bearings can extend the life of the fan.
Overall, AC fans have a simple structure that is easy to maintain and care for, as well as being highly efficient, stable, and low-noise, making them a widely used device for products such as those in the home appliance industry, machinery industry, and manufacturing equipment industry.
