We all know that the primary function of an induction heater is to heat. We are aware of its purpose, but many users are unfamiliar with how it works. Some believe that understanding the working principle is unnecessary, as knowing how to use it is sufficient. If you think this way, you're mistaken. To use an induction heater effectively, it's essential to understand its working principle. The following article mainly introduces what the working principle of an induction heater is.

What is the working principle of an inductive heater?

The inductive heater can be compared to a transformer. Its working principle involves placing a primary coil with more turns and a secondary coil with fewer turns on the same core. The voltage ratio between input and output is equal to the ratio of the coil turns, while the energy remains constant. Therefore, the secondary coil produces a high current under low-voltage conditions. For an inductive heater, the bearing acts as a short-circuited single-turn secondary coil, passing a high current at lower AC voltages, thereby generating a significant amount of heat. The heater itself and the magnetic yoke remain at a normal temperature. Since this heating method induces a current, the bearing gets magnetized. It is crucial to ensure that the bearing is demagnetized in the future to prevent it from attracting metal magnetic particles during operation.

We hope the working principle of the induction heaters we've introduced is helpful to you. If you find this knowledge not particularly practical, that's fine.
