Why Armature Core Is Laminated In Dc Machine

The rotating part of the dc machine or a dc generator is called the armature.

Why armature core is laminated in dc machine.

Safe the steal for lamination. Why the armature core in d c machines is constructed with laminated steel sheets instead of solid steel sheets. The armature core of a dc machine is laminated to reduce the eddy current loss. 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.

Armature of dc generator. Balance the weight of the core for balanced rotational motion. 11 what is the function of armature in a dc generator. The armature consists of a shaft upon which a laminated cylinder called amature core is placed.

Reduce the weight of the core. Some through holes are provided in the laminated armature core in a dc machine to. The top image depicts a solid armature while the bottom image shows an armature made of five laminations. To prevent eddy current and hysteresis.

Asked by haroon rehman. What is the main factor which governs the size and rating of an electric machine. 10 why is the armature core of a dc machine laminated. Answer for why is the armature core of a dc machine laminated.

2020 06 25 17 28 04 2020 06 25 17 28 04. Ventilate air during rotation. 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 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. The sum of the eddy currents in the laminated core is smaller than the current in the solid core. The yoke is stationary and no flux variations take place and hence the.
