What are the core materials affecting the quality of DC fans?

The specifications and sizes of DC fans are very large, and the parameters used by each customer are different, which makes the production of DC fans prone to quality problems. If one parameter, or several parameters, several specifications, and years of production, how many problems can be solved, but if there are thousands of specifications, then there are the same several. One problem, then, is that the problem has not been completely solved, and another problem has come. The most important one is the material problem. The core materials that affect the quality of DC fans are as follows.
 
First, the driver chip, the chip is not sensitive, or burned out in operation, the fan does not turn.
 
Secondly, bearing and shaft core affect the sound of fan operation
 
Other materials, such as wires, plastic frames, labels, buckles, etc., are relatively simple and less likely to cause problems.
