As is well known, many industries currently on the market are utilizing... Cooling fan From small electronic devices to large refrigerator cabinets, cooling fans play a crucial role in ensuring that product temperatures remain within a controllable range, thereby extending the lifespan of these products. The cooling fan market is vast, and competition among cooling fan manufacturers is intense. Moreover, different manufacturers offer cooling fan models with varying features and functions. As a result, consumers often find it somewhat daunting when choosing a cooling fan—uncertain about which brand or model would be the best fit for their needs. Now, let’s take a closer look together!
 
1: Bearing Type
Bearings are divided into ball bearings and oil-impregnated bearings. Oil-impregnated bearings are sleeve bearings that rely on sliding friction and use lubricating oil as a lubricant. They represent a relatively common bearing technology in the market. This type of bearing is low-cost and simple to manufacture. Its advantages include quiet operation with low noise levels during initial use, as well as an affordable price. Ball bearings, on the other hand, utilize rolling friction. They consist of two metal rings with steel balls or steel cylinders positioned between them, supplemented by some grease for lubrication. This design significantly reduces friction between bearing surfaces, effectively extending the service life of fan bearings. As a result, the heat generated by the heatsink is reduced, further prolonging its lifespan.
2: Fan Noise
In addition to cooling performance, the operating noise of fans is also a common concern among users. Fan noise is closely related to friction and air flow. The higher the fan speed and the greater the airflow, the louder the noise will be. Moreover, the vibrations inherent in the fan itself are also an important factor that cannot be overlooked. To address this issue, we’ve tried using larger-sized fans. Under the same airflow conditions, a larger fan operating at a lower speed will produce less noise than a smaller fan running at a higher speed. Another factor that we often overlook is the fan’s bearing. Since the rotating shaft and bearing experience friction and impact when the fan spins at high speeds, this is a major source of fan noise as well. Therefore, we recommend that consumers choose reputable manufacturers when purchasing cooling fans to ensure quality.
 
The above is a brief sharing of useful knowledge on distinguishing between the noise and unusual sounds produced by cooling fans.

The pivot joint is fixed at the position of the motor stator base, ensuring an appropriate gap between the rotor and the stator. Of course, there must also be a clearance between the shaft core and the bearings to prevent the shaft core from becoming locked and thus unable to function. The stator structure of the motor—hereafter referred to as the "stator"—is designed in such a way that, once power is supplied, an induced magnetic field will be generated between the rotor and the stator. The control circuit then drives the electric fan motor into operation. Therefore, in the conventional fan motor design, as long as the fan rotor, the motor stator, and the drive circuit work together via the pivot joint between the shaft core and the bearings and through magnetic field induction, the motor can operate effectively.
