Introduction

DC Fans are widely used in various applications. MR4020H12B1-RSR, a DC fan produced by NMB-MAT, is one of the most popular DC fan models. It utilizes a highly efficient Brushless Direct Current (BLDC) motor, which makes it suitable for intensive use and vibration-free operation. This fan boasts advantages such as efficiency, low noise, performance consistency, and small size.

Applications and Technical Specifications

This DC fan is frequently utilized in various applications, including small IT systems, heaters, ovens, refrigerators, and electronics cooling. Its dimensions are 40 x 40 x 20 mm, and the speed of the fan can reach up to 13,500 RPM. Its total airflow is supplied to 48 l of air per minute, while its static pressure can reach up to 1.321mmH2O.

Working Principle

The MR4020H12B1-RSR is powered by a Brushless Direct Current (BLDC) motor. The stator consists of three magnetic coils arranged in a circle, which induces current in the rotor’s winding. This current creates an energy field that interacts with the stator’s magnetic field to create motion. This magnetic cycle creates rotational energy in the permanent magnets in the rotor. The power control circuit of the DC fan controls the speed of the motor as well as the amount of power required by the fan.

Advantages

The MR4020H12B1-RSR offers advantageous features such as small size, powerful motor, high airflow, and low noise. Its small size makes it suitable for applications that require space optimization, while its powerful motor drives the fan with a speed of 13,500 RPM and a total airflow of 48 l per minute. Additionally, its specially designed blades provide noise-dampening characteristics and ensure an exceptionally quiet operation.

Conclusion

The MR4020H12B1-RSR is one of the most popular DC fan models produced by NMB-MAT. Thanks to its efficient Brushless Direct Current motor, this fan offers an exceptionally quiet operation and a high level of performance consistency. Its small size and powerful motor make it ideal for use in small IT systems, heaters, ovens, refrigerators, and electronics cooling.
