Why Must The Core Of A Transformer Be Laminated

A maximum theoretical efficiency of 25 is obtainable using usual configurations but 50 is the maximum for a transformer or inductively coupled configuration.

Why must the core of a transformer be laminated.

Transformers are basically two coils of wire wrapped around a core of iron. In a power amplifier this not only wastes power and limits operation with batteries but increases operating costs and requires higher rated output devices. Laminated magnetic core reduces eddy currents. 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 purpose of providing an iron core in a transformer is to. Reduce eddy current losses. For this reason electrically isolated laminations are utilized to manufacture transformers.

The core is laminated to reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one. A new location or just. Reduce all above losses. Comment related questions on transformers.

A transformer core is laminated to. 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. 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. They work by induction.
