The advantage of dc motors compared to induction motors (AC) is the ease of controlling when operating, although it must ignore the economic problems. For ships that move under water, will have difficulty in the operation of the generator, therefore must be provided a large number of battery accumulator for the operation of equipment on board. This battery is also used to supply electric power to dc motor propulsion drive. This is where the need to learn about the performance of dc motor to support underwater ship operations, need to be studied about the operation of dc motor when the vessel performs maneuvering operations, slow sailing, high speed sailing and other ship operations may be. In the theory of regulating the speed of motor rotation dc there are 3 methods are: first setting magnetic flux, secondly setting the anchor current and thirdly the incoming voltage regulation (terminal voltage). Motor rotation setting through terminal voltage settings is also called Ward Leonard system, this is the smoothest rotation arrangement that has a spin range from zero to motor nominal rotation. From both explanations mentioned above then in this paper will be examined the application of the dc motor as a driver on the ship that moves below the surface of the water, in this study will use ship and motor real data’s and in completing it will support by a calculation program. Observation by using software will be focused to get correlation between input voltage, motor rotation and speed of ship and torque. From the results of the assessment will be obtained conclusions about the operational dc motor for maneuvering conditions, slow sailing, fast sailing etc.
