Riunting in a synchronous motor takes place___________?
Correct answer: B. when load varies
- A. when supply voltage fluctuates
- B. when load varies
- C. when power factor is unity
- D. motor is under loaded
Explanation
Hunting, or rotor oscillation about its steady torque angle, is commonly caused by sudden changes in mechanical load. Supply disturbances can also contribute, but load variation is the standard answer here.
