Transformer Core Are Laminated For What Purpose

Electrical energy can be transferred between separate coils without a metallic conductive connection between the two circuits.

Transformer core are laminated for what purpose.

A transformer core is laminated to a reduce hysteresis loss b reduce eddy current losses c reduce copper losses d reduce all above losses. For efficient flux linking between these windings one low reluctance magnetic path common to all windings should be provided in the transformer. The main purpose of a transformer core is to provide a closed magnetic path to the magnetic flux. Without disturbing the closeness of the magnetic path we can design two types of core.

The performance of a transformer mainly depends upon the flux linkages between these windings. These are the core type and shell type. 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. Purpose of transformer core.

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. In an electrical power transformer there are primary secondary and sometimes also tertiary windings.
