The armature core of dc generator is cylindrical in shape and keyed to the rotating shaft.
Asked by haroon rehman.
The sum of the eddy currents in the laminated core is smaller than the current in the solid core.
Balance the weight of the core for balanced rotational motion.
The top image depicts a solid armature while the bottom image shows an armature made of five laminations.
Asked by wiki user.
Lamination highly reduces the eddy current loss and steel sheets provide low reluctance path to magnetic field i e decreases hysteresis loss.
The rotating part of the dc machine or a dc generator is called the armature.
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.
Answer for why is the armature core of a dc machine laminated.
To prevent eddy current and hysteresis.
10 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.
Reduce the weight of the core.
Armature of dc generator.
Some through holes are provided in the laminated armature core in a dc machine to.
The yoke is stationary and no flux variations take place and hence the.
To reduce the eddy current loss.
What is the main factor which governs the size and rating of an electric machine.
Why armature core is laminated in dc machine.
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.
