Application Field of 9WS1248H102
The 9WS1248H102 is widely used in a variety of industrial, commercial machinery, and household appliance cooling systems, such as air purifier, medical equipment, military equipment, 3C product cooling, automotive equipment, etc. It is also used in high temperature and high-power systems, such as LED lights, power amplifiers, and cameras.

Working Principle of 9WS1248H102
The 9WS1248H102 DC fan works on the principle of a motorized armature winding captured in a static magnetic field in an electromagnetic circuit. The motor armature windings consist of copper wire wound on thin metal rods, which pass through the stator’s radial slots. The motor is coupled to the fan blades through a belt or shaft, and is driven by the armature winding and the fields created by the stator’s permanent magnet. The fan blades spread the airflow across a larger area, which increases the efficiency of the motor. When the motor is in motion, the air is forced around the fins attached to the blades, thus providing cooling for the components.
