Top 10 EI Lamination Core Factory in the world

Introduction to EI Lamination Core

EI lamination cores are fundamental components in electrical transformers, inductors, and other electromagnetic devices. They are typically made of thin sheets of electrical steel, which are stacked together to form a core. The "EI" shape refers to the combination of an "E" - shaped lamination and an "I" - shaped lamination. This design provides a closed magnetic circuit, which helps to minimize magnetic leakage and improve the efficiency of the electrical device. The use of laminated cores instead of solid cores reduces eddy current losses, as the thin laminations are insulated from each other, interrupting the flow of eddy currents.
