The fan is also equipped with a tachometer output for monitoring the fan\'s speed.

In terms of working principle, the MD4028E24B-RSR fan utilizes a small electric motor to directly drive the fan\'s blades. This motor operates silently, providing an efficient and reliable cooling. The fan also utilizes a number of components to convert electrical energy into mechanical motion, which helps to power the fan. These components include a commutator, brushes, and a stator.

The brush system of the fan is the heart of the motor and is responsible for providing power and speed control to the fan blades. The brush is made up of two metal pieces that rotate around a commutator. As the fan blades rotate, they generate an electrical current that causes one of the metal pieces to move, thus creating a torque and driving the fan. The movement of the brush is regulated by the stator, allowing for speed and load control.

In summary, the MD4028E24B-RSR DC fan is a highly efficient and reliable cooling solution designed for a variety of applications. It is designed with ball-bearing technology, an automatic restart feature, and a wide voltage range, making it suitable for a number of devices. Additionally, the fan utilizes a brush system to power its blades, ensuring silent operation and excellent cooling performance.
