How do you minimize core losses?
Hysteresis and eddy current loss constitute core loss. It can be reduced by replacing solid core by laminated core... by adeeb
How eddy current losses andhysterious losses can be reduced?
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.
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 is the reason for using laminated core?
Insulation of laminated core is required to reduce the circulating current points due to touching the two plates. This results in more iron loss and heat produced
Core loss of an induction motor?
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.

How Core losses can be reduced?
by using the laminated core
Why don't we use one piece for transformer core?
If, by 'one piece', you mean solid -as opposed to laminated- then the answer is that a solid core will have significantly-higher eddy current (circulating current) losses than a solid core.

It is essential for a relay energized by alternating current to have what?
a laminated core and a shading coil

Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
Why is the core laminated?
The iron core of Transformers is laminated to reduce eddy currents, which cause a loss of energy.
How do you reduce core losses in distribution transformer?
Reducing core losses is a design responsibility of the manufacturer. They do this by laminating the core (to reduce eddy-current losses) and carefully selecting the type of material used for the core (to reduce hysteresis losses). There's very little that you, as the user, can do about reducing core losses.
