The armature core of dc generator is cylindrical in shape and keyed to the rotating shaft.
Why armature core is laminated in dc machine.
To reduce the eddy current loss.
Reduce the weight of the core.
The armature core of a dc machine is laminated to reduce the eddy current loss.
The function of armature is to rotate the conductors in a uniform magnetic field and provide a path of very low reluctance to the magnetic flux.
Motor armatures have to be made of thin laminations of iron to work efficiently a plain solid iron armature would waste a lot of energy in at least two ways the magnetic field that is produced by.
The rotating part of the dc machine or a dc generator is called the armature.

The top image depicts a solid armature while the bottom image shows an armature made of five laminations.
The yoke is stationary and no flux variations take place and hence the.

Why armature core is laminated in dc machine.
The armature consists of a shaft upon which a laminated cylinder called amature core is placed.
To prevent eddy current and hysteresis.
Asked by haroon rehman.
The sum of the eddy currents in the laminated core is smaller than the current in the solid core.
Lamination highly reduces the eddy current loss and steel sheets provide low reluctance path to magnetic field i e decreases hysteresis loss.
What is the main factor which governs the size and rating of an electric machine.
Ventilate air during rotation.
Balance the weight of the core for balanced rotational motion.
Why the armature core in d c machines is constructed with laminated steel sheets instead of solid steel sheets.
Armature of dc generator.
Answer for why is the armature core of a dc machine laminated.
Safe the steal for lamination.
