Abstract The gyro stabilizer that reduces the lateral fluctuation of a ship generates a precession torque of the gimbal using the flywheel moment of inertia. An electric motor is needed to drive the flywheel. The conventional gimbal has a problem of a increase in installation space and weight because the fastening between the flywheel and the motor is made of a belt pulley. Therefore, this paper proposes an integrated structure in which the motor is installed inside the flywheel and presents the optimal design of the built-in motor to improve performance. The mechanical and electrical effectiveness of the proposed gimbal was verified through stress analysis, electromagnetic analysis and thermal analysis.
