135. On DC diesel-electric drives, how is the speed of the DC propulsion motor primarily controlled?
The speed of the DC propulsion motor in a DC diesel-electric drive is primarily controlled by changing the generator engine speed, as this directly affects the generator's output voltage and consequently the motor's speed; altering the motor field excitation, generator polarity, or generator engine speed are not the primary control methods.
