In referring to the illustration of the Ward-Leonard drive system, what type of DC generator is used? EL-0153
Official USCG Answer & Rule Citation
Correct Answer: Option D — Separately excited generator.
Ward-Leonard drive systems utilize a separately excited DC generator where the main shunt field is powered by an independent external DC source, such as an exciter or solid-state supply. This permits precise, wide-range voltage and speed control of the connected DC propulsion or winch motor.
