Compact Diesel-Electric Drive

Today diesel-electrical drives are found almost exclusively in cruise ships, mostly in combination with the highly maneuverable POD drive. The power supply required for the electric motors is provided by means of high-performance diesel generators. The compact design evident here (diesel engine and generator are located in the same compartment) not only demands an optimum torsional stiffness level from the flexible coupling to adjust the torsional vibration state, but also a high misalignment capacity within a compact design. Added to this comes the necessity to reduce the amplitude of the structure-borne noise between the engine and generator.
