What is iron core

The iron core of a transformer is one of its key components and performs important electromagnetic functions. The iron core is usually made of silicon steel sheets (also known as silicon steel sheets), and its main function is to concentrate and guide the magnetic field, thereby improving the efficiency and performance of the transformer. Here are some key features and functions of the iron core:

High magnetic permeability: One of the main characteristics of silicon steel sheets is its high magnetic permeability, which can effectively concentrate the magnetic field lines and reduce magnetic flux leakage, thereby improving the efficiency of the transformer.

Low loss: Silicon steel sheets have low hysteresis and eddy current losses because their grain orientation and microstructure have been specially treated to reduce energy loss when the magnetic field changes.

Construction: The iron core is usually composed of multiple thin sheets or layers, each separated by insulating material to reduce eddy current losses. This construction can effectively control the path of the magnetic flux and reduce energy losses.

Improve efficiency: A high-quality iron core can effectively improve the energy efficiency of the transformer, making the transformer more efficient in the process of power transmission and conversion by reducing energy loss and heat generation.

Material selection: According to the design requirements and use environment of the transformer, different levels of silicon steel sheets can be selected to achieve the best electromagnetic performance and economic benefits.

In general, the iron core, as the core component of the transformer, directly affects the performance and efficiency of the transformer. Through careful design and reasonable selection of materials, more efficient and reliable power conversion and transmission can be achieved.
