In the industry standard production, in order to prevent the fan blade group from separating from the brushless motor during high-speed rotation, almost all the fan blade groups applied to the brushless motor limit the rotating shaft in the shaft hole of the brushless motor through a clamping ring at one end of the rotating shaft penetrating through the shaft hole, so that when a brushless motor finished product with the fan blade group is sold, the fan blade group is integrally arranged with the brushless motor, the fan blade group is difficult to take out from the brushless motor without professional skills, and when the fan blade group is assembled into the fan finished product, the disassembly difficulty is higher.

Therefore, in the field of fans using brushless motors, the fan blade set cannot be directly detached from the fan for cleaning. And in the working process of the fan, because the blades on the fan blade group rub with the air for a long time, static electricity can be generated on the blades, and the existence of the static electricity can adsorb dust mixed in the air, therefore, after the fan works for a period of time, a lot of dust can be accumulated on the blades, so that the working efficiency of the fan is seriously influenced, and in serious cases, the phenomenon of burning-out caused by overvoltage of the brushless motor due to the larger rotation resistance of the fan blade group can also occur.
