Introduction to DC Fans

DC fans are electric fans driven by DC motors, which convert electrical energy into mechanical energy through electromagnetic interaction. It consists of motor impeller, stator and rotor through the magnetic repulsion and attraction between permanent magnet of stator and rotor to drive the air flow. It works in accordance with the same principle as a conventional electric motor. DC cooling fans are nearly used in most electronic products such as computers, telephones, videos, gaming devices, stereos, and other household appliances, to ensure their normal and efficient operation.

Advantages of OD4020-12MS DC Fans

OD4020-12MS is a DC fan with a diameter of 40 * 40mm and a thickness of 20mm. The fan has a rated voltage of 12VDC, a current rating of 0.10A, and a rated power of 1.2W. It boasts several advantages. First, OD4020-12MS has a low starting voltage and robust performance. With a lower starting voltage of 4.5VDC compared to other fans in the same class, the OD4020-12MS offers superior performance and reliability.Second, the fan is low noise and energy efficient. The fan runs at a maximum noise level of 28.5dBA, which is lower than many other fans. It also has an energy saving rate of 40%.Finally, it has a long service life. The fan is designed to last up to 50,000 hours of continuous operation.

Application Field of OD4020-12MS

As mentioned above, OD4020-12MS has many advantageous features, which make it ideal for various applications. It is commonly used in computers and other electronic devices to provide cooling and ventilation. Furthermore, it can be used to cool air conditioners, electric radiators and other items such as medical instruments.

Working Principle of OD4020-12MS

The fan\'s basic principle of operation is the same as in other fans using DC motors. The fan consists of a motor, an impeller, a stator, and a rotor. When the DC power is supplied to the motor, the stator and rotor interact with each other magnetically. This causes the rotor to turn and the impeller to spin, thus pushing the air through the fan. As the air flows, it is cooled down by the fins on the motor case, providing cooling and ventilation to the electronic components.

Conclusion

The OD4020-12MS DC fan is a powerful, reliable and energy efficient fan, which can be used in numerous electronic devices to provide cooling and ventilation. With its low starting voltage, low noise and long service life, the fan is sure to meet the needs of any application.
