As the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) continues to strengthen regulations regarding ship fuel emissions, the importance of eco-friendly vessels is increasing, accompanied by advancements in related technologies. To ensure the safe operation of electric propulsion ships, extensive research is required on the maintenance and predictive maintenance technologies of propulsion systems, such as motors and rotors. However, due to the limited availability of operational data from electric propulsion ships that have not yet been commercialized conducting such studies poses significant challenges. In response, this study presents the development of a device specifically designed to generate and measure vibration data for electric motors used in electric propulsion ships. The device simulates potential failure causes, such as bearing failure and shaft misalignment, using a small-scale electric propulsion motor. During the development process, issues such as current leakage were identified and addressed through the installation of insulation pads and the replacement of couplings. To validate the performance of the developed device, vibration data from the electric motor in a normal operating state were collected and compared with data obtained using a verified measurement instrument, the oscilloscope. The results confirmed the effectiveness of the device in accurately generating and measuring relevant vibration data.
