The present invention relates to a motor-series-arrangement type vessel electric propulsion system and, more specifically, to a vessel electric propulsion system capable of efficiently placing power means propelling a vessel in an internal space of a compartment by placing the power means in series along a drive shaft such that the power means can share a load; and enabling repair work during operation without causing the vessel to stop by allowing one of a plurality of power means to be repaired while operating the rest thereof. To achieve the purpose, the vessel electric propulsion system includes: a propulsion case (10) located on one side inside a vessel, and having a compartment (11) formed therein; a propulsion part (20) including a drive shaft (22) having one side partially inserted into the propulsion case, and having the other side equipped with a propeller (21), and at least one power means (23) provided to rotate the drive shaft (22); and a power control part (30) individually including a power conversion part (31) converting a power system of the vessel into a power system required for the power means (23), and a switch part (32) opening and closing the power supplied from the power conversion part (31) to the power means (23).

    본 발명은 전동기 직렬 배치형 선박 전기추진 시스템에 관한 것으로서, 더욱 상세하게는 선박을 추진하는 동력수단이 구동축을 따라 직렬로 배치되어 부하를 분담하도록 하여 격실 내부 공간에 동력수단이 효율적으로 배치될 수 있고, 복수의 동력수단을 활용하므로 하나의 동력수단을 보수하는 경우 나머지 동력수단을 구동하여 선박을 중지하지 않고 운전 중에 보수할 수 있는 선박 전기추진 시스템에 관한 것이다. 상기 목적을 달성하기 위하여, 본 발명에 따른 선박용 전기추진 시스템은 선박 내부 일측에 위치하며, 내부에 격실(11)이 형성되는 추진케이스(10); 일측은 상기 추진케이스(10) 내부에 일부 삽입되며, 타측은 프로펠러(21)가 장착되는 구동축(22)과, 상기 구동축(22)을 회전하도록 하나 이상의 동력수단(23)이 구비되는 추진부(20); 및 상기 선박의 전력계통을 상기 동력수단(23)에 요구되는 전력계통으로 변환하는 전력변환부(31)와, 상기 전력변환부(31)에서 상기 동력수단(23)으로 공급되는 전원을 개폐하는 스위치부(32)가 각각 구비되는 전력제어부(30);를 포함한다.
