Transformer Core Are Laminated For What Purpose

These are the core type and shell type.

Transformer core are laminated for what purpose. The performance of a transformer mainly depends upon the flux linkages between these windings. Electrical energy can be transferred between separate coils without a metallic conductive connection between the two circuits. 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 a reduce hysteresis loss b reduce eddy current losses c reduce copper losses d reduce all above losses.

In an electrical power transformer there are primary secondary and sometimes also tertiary windings. For efficient flux linking between these windings one low reluctance magnetic path common to all windings should be provided in the transformer. 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. Without disturbing the closeness of the magnetic path we can design two types of core.

The main purpose of a transformer core is to provide a closed magnetic path to the magnetic flux. A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer s core which induces a varying electromotive force across any other coils wound around the same core.
