New description: : 【New technology field】 This creation is about a DC brushless centrifugal fan, especially a DC brushless centrifugal fan with high life, low noise, power saving and environmental protection. [Prior Art] According to the SPA gas exposure pad, the purpose of high static pressure is required for gas exposure. In addition, the vacuum cleaner requires high vacuum for suction, and it is often used by a lightweight and portable “centrifugal fan. It is known that the centrifugal fan used for gas exposure is mainly provided with more than one fan blade on the housing, and one side of the housing is combined with an AC or DC motor, and the AC or DC motor spindle is coupled to drive the fan. The fan blade, through the AC or DC motor spindle, reaches the rotating process of the interlocking fan blade, and the outside air is introduced into the predetermined destination. However, the centrifugal fan currently used for generating the suction force by the vacuum cleaner mainly has more than one fan blade disposed in the casing. An AC or DC motor is coupled to one side of the housing, and the AC or DC motor spindle is coupled to drive the blade, and the AC or DC motor spindle reaches the interlocking fan rotation process to introduce the air in the vacuum cleaner to a predetermined destination. Although the most common AC or DC motor centrifugal fan in the industry mentioned above has its cost advantages, the negative technical issues include: The AC or DC motor consumes a lot of power, and the call price cannot be effectively reduced. Second: The high-decibel mechanical noise generated by the AC or DC motor is more harmful to consumers. 3 M385162 Third: AC or DC The difference between the high and low speeds of the motor is small, and the high turbulence cannot be generated, so that the guided gas capacity is small, the variability of the intake air amount is poor, and the accuracy control of the associated speed is not ideal, so it cannot be made. In addition, in recent years, there are missing AC/DC series brushed motor centrifugal fans to overcome the many technical problems mentioned in the traditional AC motors, but due to AC and DC. The brush motor uses a carbon brush as the driving surface, and the carbon consumption will produce fine toner. The carbon powder will diffuse into the air, which will cause environmental pollution, and for the human body, it is easy to dope carbon due to the inhaled air. Dust particles, and improve the chronic diseases of the lungs, so the existing AC motor-type money fan, or AC-DC series brushed motor-type centrifugal fan, are not completely ideal Technical issues, still waiting for the industry to propose better solutions.
