The armature core in a DC machine is usually made of laminated iron. True or False?

Understand the Problem

The question is asking about the material typically used for the armature core in a DC machine, specifically whether it is laminated iron or not.

More Information

The armature core in a DC machine is indeed made of laminated iron. Laminations help in reducing the eddy current losses in the core, thus minimizing heat generation and improving the machine's efficiency.

Tips

A common mistake is confusing the purpose of lamination with the materials used. Lamination reduces eddy current losses but doesn't change the fact that the core is still made of iron.
