As shown in figure "B" of the illustration, what does the M-G set's three-phase drive motor mechanically drive? Illustration EL-0101
AI Explanation
The correct answer is A) the DC generator armature.
The M-G set's three-phase drive motor mechanically drives the DC generator armature, which then generates the necessary DC power for the electrical systems. This is the key function of the M-G set, to convert the ship's three-phase AC power into the required DC power.
The other answer choices are incorrect because: B) the DC generator field is electrically excited, not mechanically driven; C) the DC motor armature is not part of the M-G set; and D) the field rectifier is an electrical component, not a mechanical drive.
