What Is an AC Fan Motor?
An AC fan motor is used in a fan that runs on AC power. It uses AC power, and its drive load is a fan.
There are two types of electricity: DC power and AC power. DC power is a power source in which the current direction is always in one direction, while AC power is a power source in which the current direction is periodically switched.
Applications of AC Fan Motors
AC fan motors are used in various applications, from consumer products to industrial equipment. The most familiar example is a fan. Some electric fans are equipped with AC fan motors. Most household outlets are AC-powered, and AC fan motors are used in electric fans because of their simple construction.
Industrial applications include fans for local exhaust ventilation. They are used when working underground, in sewage tanks, or in other areas where lack of oxygen is a concern.
Principle of AC Fan Motors
An AC fan motor is an AC motor with a fan (vane) attached to its shaft axis. Eddy currents are generated in the rotor due to changes in the magnetic field generated when current is applied to the stator.
As a result, an induced current is generated by the so-called "Fleming's" right-hand (generator) law. The induced current and the magnetic field generate power by Fleming's left-hand (motor) law.
AC fan motors have two AC power sources, single-phase and 3-phase. AC motors normally do not run on single-phase alone. Therefore, single-phase AC fan motors are usually those with a built-in capacitor to advance the phase or those with a structure called shading.
The advantage of AC motors is that they are simple in construction, have fewer parts, are more robust, and have a longer service life. The disadvantage is that it is more difficult to adjust the operating speed compared to DC motors.
Since AC motors operate on commercial power, are robust, and are easy to maintain, they are expected to continue to be widely used in the future, depending on the application.
Other Information on AC Fan Motors
1. Differences Between AC Fan Motors and DC Fan Motors
The difference between AC and DC fan motors is the fan drive power source. AC fan motors operate on AC power, while DC fan motors operate on DC power.
AC fan motors have a constant rotation speed of the fan (blades) depending on the frequency of the AC power supply, while DC fan motors can inexpensively vary their rotation speed with a circuit.
2. What is an AC Axial Fan?
An AC axial fan is an axial fan driven by an AC motor. An axial fan is a fan in which the direction of airflow with the fan is in the axial direction. The wind is generated in the direction perpendicular to the direction of rotation of the blades that generate the wind (axial direction).
As an application, it is often used for cooling machines that generate heat. Relatively little increase or decrease in airflow due to resistive objects is a characteristic of axial fans. In addition to axial fans, there are centrifugal fans and oblique flow fans, which differ in the direction in which they blow air.
Centrifugal fans are fans that generate airflow orthogonally to axial fans, causing airflow in the centrifugal direction. A diagonal flow fan is like a fan between an axial flow fan and a centrifugal fan. It draws air in from the axial direction and blows air out in the diagonal direction of the shaft. It is characterized by its lightweight, small size.
3. Structure of AC Fans
A typical fan structure consists of an impeller, casing, main shaft, and bearing.
- Impeller: The impeller is the part that produces the airflow and is the heart of the fan. It is related to airflow efficiency, and various types depend on the application, environment, and other factors.
- Casing: The casing is the outer frame of the fan itself and the inner part that creates the airflow path.
- Spindle: The central shaft of the fan has the strength to support the impeller.
- Bearing: The part that receives the rotational motion of the spindle and supports the spindle while smoothing its action. The bearing reduces friction and wear. This is an essential part because the poor quality of this part can lead to failure due to mechanical wear.
