59. How is the speed of the propeller shaft directly coupled to an AC synchronous drive motor changed when powered by either a dedicated or integrated constant frequency alternator in an AC diesel- electric drive system?
Propeller shaft speed in a constant-frequency AC diesel-electric system is controlled by varying the output frequency of the power converter, as synchronous motor speed is directly tied to the input frequency.
