According to the large-flow low-noise brushless electronic fan and the automatic machining equipment thereof, the position accuracy during welding of the fan blades and the impeller is improved, automatic welding of the fan blades and the impeller is achieved, the labor intensity of workers is reduced, the working efficiency of products is improved, and the large-flow low-noise brushless electronic fan is convenient to use by a user.

Description

technical field [0001] The invention relates to the technical field of fan processing, in particular to a brushless electronic fan with large flow rate and low noise and automatic processing equipment thereof. Background technique [0002] The brushless DC motor consists of a motor body and a driver, and is a typical mechatronic product. Since the brushless DC motor operates in a self-controlled manner, it does not add an additional starting winding to the rotor like a synchronous motor with heavy load under variable frequency speed regulation, nor does it cause oscillation and out of step when the load changes suddenly. The permanent magnets of brushless DC motors with small and medium capacity are now mostly made of rare earth NdFeB materials with high magnetic energy levels. Therefore, the volume of the rare earth permanent magnet brushless motor is reduced by one frame size compared with the three-phase asynchronous motor with the same capacity. [0003] The brushless ...

Problems solved by technology

[0004] This welding method requires the welder to set the welding point with his eyesight and experience. The position accuracy is not high, and the uneven distribution of the blades makes it shake during the rotation process. The welding method needs to be operated at close range. The welder needs to wear protective clothing and walk around Walking on the roulette, the work efficiency is low and the labor intensity of the workers is high. The convenience of installation and the stability of the current structure need to be improved. Therefore, we propose a large-flow, low-noise brushless electronic fan and its automatic processing equipment.
