On an older two-generator, two-motor DC diesel-electric drive system as shown in the illustration, what are the characteristics of the main propulsion generators? Illustration EL-0141

Question

Accepted Answer

The generators of are the direct current type whose output voltage is varied by varying the generator field strength and whose output polarity is reversed by reversing the generator field polarity.

Answer

The generators of are the direct current type whose output voltage is varied by varying the generator rotational speed and whose output polarity is reversed by reversing the generator armature direction of rotation.

Answer

The generators of are the alternating current type whose output voltage is varied by varying the generator rotational speed and whose output phase sequence is reversed by reversing the generator rotating field direction of rotation.

Answer

The generators of are the alternating current type whose output voltage is varied by varying the generator field strength and whose output phase sequence is reversed by reversing the generator field polarity.
