The 9WS0812F402 is a DC fan with many features that make it an attractive option for a wide range of applications. This article will discuss the 9WS0812F402 DC fan’s application field and working principle.

Application Field

The 9WS0812F402 is a medium-sized axial fan that is rated for 24VDC operation and is suitable for a variety of cooling applications. It is designed to operate in up to 70°C environments and boasts a MTBF of 50,000 hours. The fan uses a F series two-pole brushless DC motor, which offers several advantages.

• Unmatched speed control capabilities.
• High reliability and long operating life.
• Low power consumption.
• Low running noise levels.

The 9WS0812F402 fan is specifically designed to provide efficient cooling for high-density enclosures. The fan’s high-output motor and low power consumption mean that it can provide plenty of airflow without drawing too much power. This makes it an ideal cooling solution for many applications, such as automation control systems, computers, servers, and audio/visual equipment.

Working Principle

The 9WS0812F402 fan is a DC brushless fan that operates on a two-pole DC motor. The fan utilizes a series of permanent magnets attached to the fan’s rotor to create a strong magnetic field. This magnetic field interacts with the current flowing through the fan’s stator, causing the rotor to spin. The motor’s two-pole design ensures that the rotor will always spin in the same direction, providing consistent, reliable airflow.

The fan utilizes an integrated electronic speed controller to adjust its speed. The speed controller utilizes pulse-width-modulation (PWM) technology to vary the amount of current being sent to the fan’s motor. Increasing the current will cause the fan to spin faster, while decreasing the current will cause the fan to spin slower. This allows the user to set the fan’s speed depending on their requirements.

The 9WS0812F402 DC fan is a reliable and efficient cooling solution that can be used in a variety of applications. Its low power consumption and low operating noise make it an ideal cooling solution for high-density enclosures. Its two-pole brushless DC motor and integrated speed controller provide precise control over the fan’s speed, making it a versatile and flexible choice for a variety of applications.
