Laminated cores, in electrical machines, are used to reduce____________?
Correct answer: B. eddy current loss
- A. copper loss
- B. eddy current loss
- C. hysteresis loss
- D. all of the above
Explanation
Laminating the core breaks up the paths available for circulating eddy currents and increases their effective resistance. It therefore reduces eddy-current loss, not copper or hysteresis loss directly.
