Transformer core is laminated.
A maximum theoretical efficiency of 25 is obtainable using usual configurations but 50 is the maximum for a transformer or inductively coupled configuration.
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.
Reduce all above losses.
Reduce eddy current losses.
A new location or just.
Laminated magnetic core reduces eddy currents.
The core of any transformer is laminated for the following reasons.
For this reason electrically isolated laminations are utilized to manufacture transformers.
The central iron core is constructed from of a highly permeable material made from thin silicon steel laminations assembled together to provide the required magnetic path with the minimum of losses.
A transformer core is laminated to.
To control it s weight regulate the energy loss due to eddy currents increase the formation secondary voltage.
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.

Laminated core is a rectangular shaped type of soft magnetic core.
The core of a transformer is laminated so that energy loss due to eddy currents may be reduced.
Which has been specially designed to carry large input and output power transmissions since loss due to eddy currents is less.
Which has been extensively used in power transformers distribution transformers and isolation transformers.
This ensures that the parts of core are separated from each other and there is less area available for eddy currents rusting of core may be prevented by coating of anti rust material.
The way to reduce these unwanted power losses is to construct the transformer core from thin steel laminations.
