Eddy Current Laminated Core Transformer

Each lamination sheet will have an eddy current circulates within it.

Eddy current laminated core transformer.

The transformer core made from e and i lamination transformer core made from e and i lamination eddy currents are generated in a transformer core which heats the core and causes losses by altering the current. Intro to eddy current theory duration. The central iron core is constructed from of a highly permeable material made from thin silicon steel laminations assembled together to provide the required magnetic path with the minimum of losses. If the core is one component its size is wide and thus small which reduces losses due to a greater current.

The eddy current loss is proportional to f 2. A transformer core is laminated to a reduce hysteresis loss b reduce eddy current losses c reduce copper losses d reduce all above losses. In an ac transformer using thin sheets of iron coated with lacquer and glued together can minimize loss caused by eddy currents that would flow in a solid iron core. The result of all this insulation is that the unwanted induced eddy current power loss in the core is greatly reduced and it is for this reason why the magnetic iron circuit of every transformer and other electro magnetic machines are all laminated.

So that resostance increase to resist circulating current. The resistivity of the steel sheet itself is high reducing the eddy current losses by making the laminations very thin. A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical electromechanical and magnetic devices such as electromagnets transformers electric motors generators inductors magnetic recording heads and magnetic assemblies it is made of ferromagnetic metal such as iron or ferrimagnetic compounds such as ferrites.

So at higher frequencies the eddy current loss is very high. Why the core of transformer is made up of laminated core. So it is the current which circulates in iron core of the traffo. The sum of individual eddy current of the laminations are very less compared to that of using single solid iron core.

The core is made from e and i lamination.
