Question

Which is the way to reduce iron loss in induction motors select one: a. Increase stator yoke b. All the above c. Low loss magnetic material d. Reduce flux density

Answer 1

Explanation:

➡️ The wire in the coil itself also contributes to audible noise (it vibrates with the frequency of the magnetic field), but does not contribute to core losses. So the short answer is that core losses in a transformer do not pass energy from primary to secondary, thus they are not proportional to load.
