Zusammenfassung:The utility model belongs to the technical field of brushless direct current fans, and particularly provides a brushless direct current fan with low electromagnetic radiation. The fan comprises a shell assembly, a stator assembly, a rotor assembly and blades. The shell assembly comprises an outer frame, an inner frame, a solid connecting frame, a hollow connecting frame, a wiring hole, a grounding piece, a slotted pan head screw and a shielded wire. A printed circuit board assembly and a shell assembly of the fan form a grounding design through a grounding piece, a slotted pan head screw and a shielded wire, a low-impedance access is provided for high-frequency interference signals, and meanwhile interference of the high-frequency signals on an electronic system is restrained. In the design process of the printed circuit board, the total length of the circuit is shortened to the greatest extent in accordance with the principle of first complexity and then simplicity and first large and then small; and heat in
