The continuous advancement of technology, Cooling fan The applications of cooling systems are continually expanding, demonstrating that they can be used in a wide variety of settings and on diverse types of equipment—ranging from large-scale applications like aircraft and buses to smaller devices such as electric toothbrushes and electronic masks. Of course, each of these devices has a finite lifespan, and when the cooling fan stops working, it can directly affect the device’s operational life. So, what factors need to be considered when evaluating the reliability of cooling fans?
1. Temperature Rise: The temperature rise refers to the increase in temperature of the motor itself relative to the ambient temperature. Typically, during operation, the temperature rise of a motor should not exceed 110 degrees.
 
2. Current: The chip’s current-handling capability must be carefully considered. During design, the actual current will be lower than the chip’s rated current.
 
3. Voltage Resistance: Regarding the voltage stability of customer products and the voltage tolerance of cooling fans, some products have unstable voltages that tend to be higher than expected.
 
4. Anti-interference: Some products are installed in environments with strong static electricity where cooling fans are used, so it’s necessary to... Cooling fan Add protective treatment
 
5. Waterproofing: For some products designed to operate in humid environments or underwater, we need to consider the waterproof rating of the cooling fan.
 
The above 5 items are Cooling fan In addition to the reliability factors that must be considered in and of themselves, there are also installation-related factors, odor considerations, and other aspects that require adjustments to cooling fans. Whenever customers raise these issues, we will promptly implement appropriate countermeasures.

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.
