DC Fans

DC fans are a type of cooling system that is typically used in a wide variety of consumer electronics. It utilizes a direct current (DC) motor to generate airflow through its rearward blades. This type of fan has many advantages over traditional fans, such as being smaller, lighter, and more reliable. DC fans are also capable of producing higher airflow and static pressures. In addition, DC fans offer quieter operation than classical fans.

MR4020E12B1-RSR Application Field and Working Principle

The MR4020E12B1-RSR is a long life, durable DC brushless fan meets the demands of high performance cooling applications. It features an optimized DC brushless motor which allows high air pressure with low noise levels. The motor consists of a permanent magnet rotating assembly, stator windings, and an electronic control module. The rotor is magnetized in lengthways axial directions. The magnetic field extends outward in both directions and interacts with the stator windings. When the rotor rotates, the changes in the magnetic field induces an alternating current in the stator windings. This causes rotation of the shaft and an increase in air flow.

The MR4020E12B1-RSR is designed for use in a variety of applications, including personal computers, TVs, routers, and automotive applications. It features a range of stator windings, from 3.2 to 8.0 watts, that provide a range of air flow from 17.5 to 38.5 CFM. The optimal design provides durable performance while supplying a strong static pressure, with no fan shuddering. The motor is also designed to allow it to start up under low input current, preventing the fan from stalling when starting.

The MR4020E12B1-RSR also features a range of accessories, including a controller, filter, and brackets, which allow the fan to be conveniently installed in a variety of locations. The controller allows for the speed of the fan to be adjusted in-circuit, giving the user control over the air flow and noise levels. The filter allows for the fan to be used in dusty environments, helping to protect the fan in adverse conditions. The bracket can also be used to secure the fan in place, ensuring it does not become dislodged during operation.

The MR4020E12B1-RSR is a top of the line DC fan which can be used in a variety of applications. It provides strong performance with low noise levels, whilst allowing for in-circuit speed control. Additionally, it has a a wide range of accessories, enabling users to install and customize the fan to their specific needs.
