Some through holes are provided in the laminated armature core in a dc machine to.
Why armature core is laminated in dc machine.
Ventilate air during rotation.
The armature consists of a shaft upon which a laminated cylinder called amature core is placed.
The yoke is stationary and no flux variations take place and hence the.
Answer for why is the armature core of a dc machine laminated.
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.
11 what is the function of armature in a dc generator.
To reduce the eddy current loss.
To prevent eddy current and hysteresis.
The armature core of dc generator is cylindrical in shape and keyed to the rotating shaft.
Why the armature core in d c machines is constructed with laminated steel sheets instead of solid steel sheets.
Reduce the weight of the core.
Balance the weight of the core for balanced rotational motion.

Armature core rotates and comes under n and s poles alternately and this flux variations produce hysteresis and eddy current losses in the core and hence the core is laminated.
The top image depicts a solid armature while the bottom image shows an armature made of five laminations.
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.
The armature core of a dc machine is laminated to reduce the eddy current loss.
