There are typically three main types of iron losses in electrical machines:
1. Hysteresis Loss – This occurs due to the magnetization and demagnetization of the iron core as the magnetic field changes.
2. Eddy Current Loss – These are losses caused by circulating currents induced in the iron core due to the changing magnetic fields.
3. Implementation Losses (or Stray Losses) – These can result from imperfections in the material or external factors affecting the efficiency of the magnetic circuit.
These losses contribute to the overall inefficiency in magnetic materials used in electrical machines.
Answer: a
Explanation: There are basically 2 losses present under the core loss or iron loss. They
are hysteresis loss and the eddy current loss.
Two main types of iron losses are present: hysteresis loss and eddy current loss.
