Transformer Cores Are Laminated With

Wikipedia defines eddy currents as.

Transformer cores are laminated with.

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. Eddy currents are loops of electric current induced within conductors by a changing magnetic field in the conductor due to faraday s law of 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.

However when a magnetic flux flows in a transformers steel core two types of losses occur in the. The purpose of providing an iron core in a transformer is to. Laminated core transformer showing edge of laminations at top of photo interleaved e i transformer laminations showing air gap and flux paths transformers for use at power or audio frequencies typically have cores made of high permeability silicon steel. Reduce all above losses.

The iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer. A transformer core is laminated to. But a solid iron core has some own disadvantage due to to some losses. Reduce eddy current losses.

Most transformer cores are constructed from low carbon steels which can have permeabilities in the order of 1500 compared with just 1 0 for air. Thus to reduce the losses solid core is not used in transformer.
