Abstract
A modular electric propulsion device for ships according to an embodiment of the present disclosure may be easily mounted in a ship after removing an existing engine from the ship because a switch board for power distribution, and an inverter and a motor for power conversion are modularized inside a single casing, and may be installed in a minimum space for installation because a distance between motor rotation shafts may be made close to each other even when two modular electric propulsion devices for ships are mounted in a dual installation manner.
Claims9
A modular electric propulsion device for ships, the device comprising:
- a casing;
- a space partition plate provided inside the casing and dividing an inner space of the casing into a plurality of different spaces;
- a switch board fixed to the space partition plate in a first space and receiving and distributing external power, and separately outputting the power as power to be supplied to an inverter and power to be supplied to loads of a hull;
- the inverter fixed to the space partition plate in a second space among the spaces such that the inverter is spaced apart from the switch board, the inverter being configured to convert and output the power supplied from the switch board;
- and
- a motor which is fixed in a third space among the spaces such that the motor is spaced apart from the switch board and the inverter, the motor being configured to generate driving force by receiving the power from the inverter,
- wherein no engine is provided inside the casing,
- only the motor is provided as a single power source, and
- a rotation shaft of the motor protrudes directly from a front surface which is a surface facing a rear of the hull among surfaces of the casing.
