A hysteresis motor works on the principle of__________?
Correct answer: A. hysteresis loss
- A. hysteresis loss
- B. magnetisation of rotor
- C. eddy current loss
- D. electromagnetic induction
Explanation
A hysteresis motor develops torque because the rotor magnetisation lags the rotating stator field, producing hysteresis torque associated with hysteresis loss. Eddy-current and induction effects are not the primary operating principle here.
