Why are coil windings prone to burning out?

WhyCoil PlateWhy is it easy to burn out? It is common for the induction cooker's coil to burn out due to excessive use, but it is unreasonable for the coil to burn out because of overuse. For example, in hot pot restaurants, the induction cookers are used for a long time, and it is very rare for the coils to burn out. However, in our home, it seems that the coils are often burned out.
For high-power coil plates, the wire diameter of the coil plate requires a larger size. In fact, during the actual development process, this relationship cannot be used to judge whether it is feasible or not. The two important parameters of the coil plate are inductance and its Q value. The key is to test the working temperature in the machine. Generally, if the temperature does not exceed 180 degrees, I have seen the temperature of the price machine coil plate reach 190 degrees. Otherwise, the hand coil of the coil plate will break first. The higher the power of the high-power coil plate, the greater the current in the coil. Of course, the temperature generated will also be higher. Therefore, under the condition of ensuring good heat dissipation, both inductance and Q value should be improved.
In fact, when we choose an induction cooker, we should pay attention to the coil issue. The coil is theoretically made of copper wire. The images show two coil plates, the left one is good, and the right one is made of aluminum. Overall, the copper wire is denser, while the poor quality one is looser. The copper wire is heavier in terms of airflow. However, it cannot be seen from the surface because there is a layer of paint covering it. Therefore, to understand this coil issue, it is necessary to disassemble it. The white one is aluminum, and the red one is copper.
We see how to identify the induction cooker's coil.Coil PlateWhen we know how to identify the induction cooker's coil, we should also know how to choose an induction cooker. If it really burns out, we can directly replace the induction cooker's coil.
