DC Fans

The term "DC fan" describes a wide range of fans driven by direct current (DC) power, from small 12 volt fans designed to cool an enclosed area such as a computer cabinet to large 24 volt industrial fans used in a variety of applications.

The 9S1212M402 DC fan is a small, low-cost fan motor specifically designed for use in consumer and office electronics. It is a compact, low-noise, brushless DC motor capable of producing more than 10 watts of power output, which makes it well suited for high-performance cooling applications. The fan comes with both a 5V and 12V operating voltage range and is designed to operate in a wide range of environmental conditions.

The 9S1212M402 DC fan is designed to be highly reliable and highly efficient. Its integrated circuitry and regenerative braking enable it to reach speeds up to 10,000 revolutions per minute (RPMs). The fan also has a low-level magnetic field, which can help reduce the interference from electric fields in sensitive electronic systems. The fan also has a very high tolerance for voltage transients, ensuring its reliability when used in any environment.

The 9S1212M402 DC fan application field can be divided into two primary categories: cooling and ventilation. The fan\'s high power output and high-speed motor make it ideal for cooling applications. The fan can be used to cool computers, TVs, printer, audio equipment, and other electronics by drawing in air and providing aided circulation. The fan is also capable of dissipating small amounts of heat from electrical components.

The fan can also be used in ventilation applications, such as circulating air in automotive, industrial, and military environments. Its high RPMs make it suitable for moving large volumes of air at low pressures. The fan is—in some cases— even capable of driving small amounts of fluid, facilitating liquid cooling applications. The fan\'s small size and low power consumption also make it ideal for use in portable electronics.

The 9S1212M402 DC fan’s working principle is simple. When the fan is activated, a small electric current flows through the copper windings located in the stator. This electric current creates a magnetic field, which interacts with the fan\'s rotor-mounted permanent magnets. This interaction causes the fan to rotate within its housing, creating air movement.

As the fan spins, air enters one side of the fan and is pushed out of the other side, providing airflow to the surrounding area. The fan\'s speed and amount of airflow can be controlled by adjusting the electric current, allowing the speed to be adjusted to optimize cooling or ventilation performance.

The 9S1212M402 DC fan is a great solution for a wide range of cooling and ventilation applications. Its small size and low cost make it an ideal solution for consumer electronics, yet its reliable and efficient design make it suitable for a wide range of industrial applications as well.
