In the modern era of science and technology, the popularization and use of electronic equipment inevitably brings about the problem of electromagnetic interference. Especially in the use of cooling fans, traditional brushed fans often produce electromagnetic interference, which brings inconvenience to users. This time brushless cooling fan is your best choice. How does it reduce electromagnetic interference? Mainly through four ways:

Use an electronic controller instead of a mechanical commutator: Just like our A17051A industrial high-speed axial flow brushless cooling power cabinet fan uses an electronic controller instead of the mechanical commutator of the traditional brushed cooling fan. In this way, electromagnetic interference caused by mechanical friction can be reduced, while the electronic controller can precisely control the speed and current of the motor, thereby reducing electromagnetic radiation.

Ground and grounding: Some wholesale 24v DC brushless fans will also improve the ground and ground, good grounding can reduce electromagnetic radiation and interference. Ensure that the ground cables of the brushless cooling fan are securely connected to the grounding system of the entire system.

Then the previous answer to eliminate the brushless cooling fan electromagnetic interference way.

The use of shielding materials: the shell of the brushless cooling fan is usually made of metal materials, like our A08025 brushless motor cooling axial fan is made of aluminum alloy shell, and shielding materials are used on the circuit board and cable, so that the spread of electromagnetic radiation can be effectively blocked and the conduction of interference can be reduced.

Optimize motor design: The motor design of brushless cooling fans is often more complex than that of brushed motors, requiring precise electromagnetic fields

Analysis and optimization. Some wholesale AC brushless cooling fans can reduce electromagnetic radiation by optimizing motor design, brushless cooling fan motors usually use three-phase structure, through reasonable winding design and magnetic field distribution optimization, you can reduce the occurrence of electromagnetic interference.
