Overview of the development of marine electric propulsion

Ship electric propulsion is not a new term. This term appeared in 1838 and has a history of more than 160 years. Ship electric propulsion develops with the continuous progress of the ship and shipping industry and the electrical and power electronic technology. In the 

Application of ship electric propulsion

Application of ship electric propulsion

Electric propulsion is mostly used on ships with the following characteristics:(1) Ships requiring high maneuverability;(2) Ships with special nature of work are required;(3) Ships with large-capacity auxiliary machinery;(4) Military ships.The use of electric propulsion on some of the following ships has particularly outstanding advantages, and 

Characteristics of ship electric propulsion

Characteristics of ship electric propulsion

Compared with direct or geared propulsion, the main advantages of electric propulsion are: (1) Flexible layout and installation. The prime mover of large ships is almost without exception installed in the lower space of the stern, and at the same time, a longer drive shaft 

The composition and classification of electric propulsion system

The composition and classification of electric propulsion system

The ship’s electric propulsion system is generally composed of propellers, electric motors, generators, prime movers and control equipment. Its structure is shown in Figure 1. Among them, the mechanical energy of the prime mover Y is transformed into electrical energy by the generator G, which
