Laminated Iron Core In Transformer

Instead of having one big solid iron core as the magnetic core material of the transformer or coil the magnetic path is split up into many thin pressed steel shapes called laminations.

Laminated iron core in transformer.

Iron core is thin laminated in transformer to avoid the loss of eddy current. The iron core made by thin metal strips and lamination insulated by a coat of varnishes or papers. Transformers are basically two coils of wire wrapped around a core of iron. The eddy currents cause energy to be lost from the transformer as they heat up the core meaning that electrical energy is being wasted as unwanted heat energy.

The laminations used in a transformer construction are very thin strips of insulated metal joined together to produce a solid but laminated core as we saw above. Why iron core is thin laminated in transformer the iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer. The iron core transformer provides better power transfer than does the air core transformer. Laminated core is a rectangular shaped type of soft magnetic core.

Which has been extensively used in power transformers distribution transformers and isolation transformers. The majority of transformers you will encounter in navy equipment contain laminated steel cores. Which has been specially designed to carry large input and output power transmissions since loss due to eddy currents is less. Carbonyl iron cores are often called rf cores.

They contain significant amount of carbon. Laminated means made up of insulated layers of iron glued together rather than being in a single solid lump. Thus it provides for the efficient transfer of power. Each metal strip has thickness near about the o 5mm.

Eddy current is induced in core and circulates normal to the width of the core causing heat. You can also choose from ei lamination steel coil laminated transformer core as well as from non oriented silicon steel oriented silicon steel laminated transformer core and whether laminated transformer core is aisi gb or astm. The reason we laminate the iron cores in transformers is because we want to limit what are called eddy currents. The as prepared particles e type and have onion like skin with concentric shells separated with a gap.

A transformer whose core is constructed of laminated sheets of steel dissipates heat readily.
