To reduce the eddy current loss.
Why armature core is laminated in dc machine.
Why armature core is laminated in dc machine.
Asked by haroon rehman.
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.
Lamination highly reduces the eddy current loss and steel sheets provide low reluctance path to magnetic field i e decreases hysteresis loss.
The armature core of a dc machine is laminated to reduce the eddy current loss.
Ventilate air during rotation.
What is the main factor which governs the size and rating of an electric machine.
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 rotating part of the dc machine or a dc generator is called the armature.
The armature consists of a shaft upon which a laminated cylinder called amature core is placed.
The top image depicts a solid armature while the bottom image shows an armature made of five laminations.
Why the armature core in d c machines is constructed with laminated steel sheets instead of solid steel sheets.
Some through holes are provided in the laminated armature core in a dc machine to.
Reduce the weight of the core.

11 what is the function of armature in a dc generator.

10 why is the armature core of a dc machine laminated.
The sum of the eddy currents in the laminated core is smaller than the current in the solid core.
The armature core of dc generator is cylindrical in shape and keyed to the rotating shaft.
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.
To prevent eddy current and hysteresis.
Safe the steal for lamination.
