Reduce eddy current losses.
Why transformer core is laminated.
For this reason electrically isolated laminations are utilized to manufacture transformers.
The core is not designed to have any currents flow through it.
But a solid iron core has some own disadvantage due to to some losses.
Why is the core of a transformer laminated.
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.
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.
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 magnetic core reduces eddy currents.
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.
The purpose of providing an iron core in a transformer is to.
It is however a conducting loop that experiences a changing magnetic field it will therefore have small current induced in it.
Eddy current is induced in core and circulates normal to the width of the core causing heat.
