Laminations of core are generally made of________________?
Correct answer: C. silicon steel
- A. case iron
- B. carbon
- C. silicon steel
- D. stainless steel
Explanation
Armature-core laminations are made from silicon steel because its high electrical resistivity reduces eddy-current loss and its magnetic properties keep hysteresis loss low. Cast iron, carbon, and stainless steel are not the standard core material.
