In which single-phase motor, the rotor has no teeth or winding ?
Correct answer: C. Hysteresis motor
- A. Split phase motor
- B. Reluctance motor
- C. Hysteresis motor
- D. Universal motor
Explanation
A hysteresis motor uses a smooth cylindrical rotor made of hard magnetic material, with no rotor teeth, slots or electrical winding. Its torque is produced by hysteresis between the rotating field and the rotor material.
