Under which of the following conditions hunting of synchronous motor is likely to occur?
Correct answer: A. Periodic variation of load
- A. Periodic variation of load
- B. Over-excitation
- C. Over-loading for long periods
- D. Small and constant load
Explanation
Hunting is the oscillation of the rotor about its equilibrium position when the torque or load changes periodically. A periodic variation of load repeatedly disturbs the rotor angle and produces this effect.
