DC Fan, also known as brushless DC fan, is a fan powered by DC motor and is a type of precision motor. DC fan, in the form of axial fan and radial fan, is widely used in computers, air conditioners, refrigerators, ovens, laser printers and small home appliances. DC fans can be subdivided into two major categories: vaneaxial fan and blade type axial fan.

9WF0824S402 is a DC fan that is part of the blade type axial fan category. It is largely composed of a motor, a fan, and a frame. The motor is made of a DC permanent magnet motor, along with a stator, a rotor, an end bell, an impeller, and a control circuit. The stator is composed of the stator core, the stator coils, and the brushless DC motor controller (which is also known as electronic commutator). The stator core is made of two sections of pre-wound coils, the rotor, and the winding wires. The wiring of the stator coils is connected to the bottom of the rotor so that the output shaft of the motor drives the fan. The fan has both a stator and an impeller and it rotates with the airflow produced by the motor. The frame is composed of a hub, a blade, and a stator rim. It fixes the impeller, the stator, and the motor together.

The working principle of 9WF0824S402 is based on the principle of a rotating magnetic field. Due to the arrangenment of the stator coils and the rotor, the permanent magnet motor produces a rotating magnetic field when its stator coils are energized by a DC voltage. This rotating magnetic field will interact with the rotor, producing a torque that causes the rotor to rotate. The rotating speed can be adjusted according to the volage of the energized coils (or motor speed control current). The rotating speed of the motor will rotate the impeller and the fan, thus forming a strong air flow. The 9WF0824S402 can reach the air flow of 20.39 cubic feet per minute and the static pressure of 0.47 inch H2O.

9WF0824S402 is a widely used fan with its high quality, simple structure, and easy maintenance. It can be widely used in ovens, air conditioners, dishwashers, and computer components. It can also be used in some precise instruments.. Meanwhile, it can also be applied in electronic products which require heat dissipation and cooling, such as laser printer and refrigerators.
