eddy current can be reduced by using laminated cores. and also be reducing the thickness of the stampings. transformer iron loss is the combination of eddy current loss and hysterisis loss. both the losses depend on core of the transformer and iron loss is a constant loss.

Does a laminated iron core increase eddy current losses?

No, the purpose of laminating the core is to reduceeddy-current losses.


How is eddy current related to the thickness of the stampings of core?

A: Eddy currents are current losses if an iron bolt is used to hold the core lamination together that alone will cause losses. Usually a brass bolt is used to eliminate losses

Core loss of an induction motor?

Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.


What is eddi current?

An 'eddy' (not 'eddi'!) current is a current that flows in the magnetic circuit (core) of an electrical machine, due to a voltage induced into that core by a changing magnetic field. Eddy currents cause energy losses in electrical machines. To minimise eddy currents and, therefore, their losses, machines use laminated cores which restrict the paths through which eddy currents can flow.

What are the losses of a transformer?

Various energy losses occur in transformers:Copper losses, the resistance to the current flow in the windings which heats the conductors.Iron losses, which are of two kinds:eddy current losses which flow in the laminations of the core caused by the magnetization and re-magnetisation of the core, which also causes heatingof the core. Eddy current losses can be greatly reduced by not making the out of a solid piece of iron. That is why transformer cores are generally made of lots of separate thin "laminations" which are insulated from one another by being bonded together using an epoxy resin adhesive.hysteresis losses which are again caused by the magnetizing and de-magnetising of the core. These are reduced by making the laminations of silicon steels, which have lower hysteresis losses than plain iron.Together all these losses lead to a total efficiency of about 97 to 98%, which will alter depending upon the load current that the transformer is supplying.


Why core loss depends on voltage?

Core loss depends on voltage because it is primarily due to hysteresis and eddy current losses in the magnetic core material. When the voltage increases, it leads to higher magnetic flux density variations within the core material, causing an increase in hysteresis and eddy current losses, thus resulting in higher core losses.
