What is a transformer inductor core?

Transformer inductor core is an important component in a transformer, which is mainly responsible for transmitting the magnetic field and increasing the inductance, thus improving the efficiency and performance of the transformer. Inductor cores are usually made of silicon steel sheets or iron oxide magnetic materials, and their main function is to provide low permeability and high inductance while reducing hysteresis and eddy current losses.

The design and manufacture of the transformer inductor core directly affects the performance and efficiency of the transformer. Typically, inductor cores will use multi-layer windings, where insulated silicon steel sheets or iron oxide magnetic materials are wrapped together through insulating paper to form a toroidal core. This design reduces eddy current losses and hysteresis losses, increases permeability and inductance, and thus improves the efficiency of the transformer.

Inductor cores are usually round or rectangular in shape and require precise design and machining during the manufacturing process. The size and shape of the core affects the inductance and coupling coefficient of the transformer, which in turn affects the performance and power transfer efficiency of the transformer. Therefore, when designing a transformer, it is necessary to reasonably select and design the inductive iron core according to the voltage, current, power and other parameters, in order to achieve the purpose of improving efficiency and reducing losses.

In general, the transformer inductor core is an indispensable part of the transformer, which plays an important role in carrying magnetic field, increasing inductance, reducing losses, and directly affects the performance and efficiency of the transformer. In the design and manufacture of transformers, special attention needs to be paid to the selection of materials, shape and processing technology of the inductor core to ensure the stable operation and efficient work of the transformer.
