In a D.C. generator the magnetic neutral axis coincides with the geometrical neutral axis, when_______________?
Correct answer: A. there is no load on|he generator
- A. there is no load on|he generator
- B. the generator runs on full load
- C. the generator runs on overload
- D. the generator runs on designed speed
Explanation
With no armature current, armature reaction is absent, so the magnetic flux axis is not displaced. The magnetic and geometrical neutral axes therefore coincide at no load.
