9GA0612K1021

DC Fans, such as 9GA0612K1021, are electric fans specially designed for DC power supply system. It is a small-sized motor whose structure is similar to AC motors, but their operating principles are very different. In DC motor, the stator and the rotor are axially aligned, with the rotor directly driven by the permanent magnet field generated by the stator.

The coils of the stator wound with insulated copper wire make the rotor rotate by generating magnetic field. When the AC waves of the applied voltage reach the desired magnetic field, the propulsion of the rotor is realized and the rotating speed is changed according to the difference of the applied voltage.

DC fans have a wide range of applications. They are used in various electronic equipments such as computers, microcontrollers, video recorders, microwaves, and more. In addition, they are widely used in automotive, transportation, and home appliances industries. They are also suitable for industrial applications such as petroleum, chemical, medical, and so on.

The working principle of 9GA0612K1021 is based on DC motor. It works by passing electric current through two stationary coils mounted on the core of the motor. The current in the coils produces a magnetic field that interacts with the permanent magnet field of the rotor, thus generating a force which causes the rotor to rotate. The speed of the rotor could be adjusted by changing the voltage applied to the stator.

DC fans have many advantages over other electric fans. They have a higher load capacity, better performance, higher efficiency, and a longer lifespan. They are also highly reliable and have low maintenance costs. Furthermore, they provide a safe operating environment for electronic devices since they do not produce electric sparks or noise.

In conclusion, 9GA0612K1021 DC fan has a wide range of applications and its working principle is based on the DC motor. It has many advantages such as high reliability, performance, and efficiency. Moreover, it is a safe choice for electronic devices since it does not generate electric sparks or noise.
