DC Fans

DC fans are electric motors that are specially designed to move air through an enclosure. The motors used in DC fans range from simple three-phase motors to brushless DC motors equipped with magnets and commutators. The voltage applied to a DC fan is usually greater than the voltage applied to the motor, allowing it to spin at faster speeds. This makes them ideal for applications where a steady and powerful airflow is required.

9CRD0412P5J03 Application Field and Working Principle

The 9CRD0412P5J03 fan is a 12V DC fan that features a fan size of 40mm x 40mm x 20mm and a mehanical draw of 0.19A. This fan is designed for use in small electronics enclosures that require a steady and powerful airflow. The 9CRD0412P5J03 operates on Brushless DC motor technology and utilizes commutation for efficient operation and long life. It has a high speed of 6500 RPM and a low noise level of 24.5 dBA, making it perfect for most applications.

The motor in the 9CRD0412P5J03 uses brushes and magnets to create a rotational field. As the motor rotates, it generates a magnetic field which is then used to create an electric current in the commutator. This electric current is then used to power the fan wheel, causing it to rotate and move the required amount of air. The brushes in the motor are used to regulate the flow of electricity to the commutator, thereby controlling the speed of the fan.

The fan itself is made up of two components: a fan wheel and an impeller. The fan wheel pushes air through the enclosure while the impeller moves the air to the desired location. The fan wheel is composed of a series of blades that rotate rapidly in order to move air through the system. The impeller makes use of multiple stationary vanes to direct the airflow. This allows the fan to provide very reliable airflow with minimal noise output.

The 9CRD0412P5J03 is a great choice for applications that require a quiet and reliable airflow. Its brushless DC motor technology ensures efficient operation and its low noise level makes it suitable for even the most sensitive of applications. With a high speed of 6500 RPM and a mechanical draw of 0.19A, the 9CRD0412P5J03 is an extremely powerful fan perfect for applications that require efficient and loud operation.
