Armature of a synchronous machine is____________?
Correct answer: D. all of the above reasons
- A. of reducing number of slip rings on the rotor
- B. armature is associated with large power as compared to the field circuits
- C. of difficulty of providing high voltage insulation on rotor
- D. all of the above reasons
Explanation
The armature is placed on the stator because it carries the larger power, permits easier high-voltage insulation, and avoids carrying heavy currents through rotor slip rings. Therefore all three listed reasons apply.
