Why Must The Core Of A Transformer Be Laminated

Reduce all above losses.

Why must the core of a transformer be laminated.

Reduce eddy current losses. In a power amplifier this not only wastes power and limits operation with batteries but increases operating costs and requires higher rated output devices. The iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer. They work by induction.

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. A transformer core is laminated to. The purpose of providing an iron core in a transformer is to. Comment related questions on transformers.

Why iron core is thin laminated in transformer. A new location or just. Laminated magnetic core reduces eddy currents. A maximum theoretical efficiency of 25 is obtainable using usual configurations but 50 is the maximum for a transformer or inductively coupled configuration.

Transformers are basically two coils of wire wrapped around a core of iron. The figure below displays side view of transformer core where the eddy current flow in a solid and laminated core is indicated with red colored lines. Eddy current is induced in core and circulates normal to the width of the core causing heat. The reason we laminate the iron cores in transformers is because we want to limit what are called eddy currents.
