The core of a transformer is laminated so that energy loss due to eddy currents may be reduced.
A transformer core is laminated to.
This arrangement increases the overall resistance of the core.
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.
Transformer core laminations the core is not generally made of the solid transformer core material that is solid crgo silicon steel.
You can buy powdered iron.
A transformer core is laminated to a reduce hysteresis loss b reduce eddy current losses c reduce copper losses d reduce all above losses ans.
Steel sheets have a resistance to magnetic reversal and the silicon reduces that.
For the transformer core you want to use steel laminations with 3 silicon for the magnetic properties.
The core laminated transformer to neutralize these eddy currents it is necessary to section the core into very thin sheets isolating them from others by means of a layer of varnish or oxide in such a way that even if one exceeds the other the eddy currents in a sheet could never be short circuited with the currents of the adjacent sheets.
There are many causes due to which energy is lost in transformer.
Eddy current is one of them.
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.
So as to minimize the lost heat by eddy currents the core of transformer is laminated.
However you can make your own custom core that actually works quite well.
