Ward Leonard method of speed control is basically a______________?
Correct answer: B. armature controlled method
- A. field control method
- B. armature controlled method
- C. field diverter
- D. frequency control method
Explanation
The Ward Leonard system varies the DC motor armature voltage by supplying it from a separately driven generator, while the field is usually kept constant. It is therefore fundamentally an armature-control method.
