Abstract: A rotor of an electrical rotating machine includes: a rotor shaft; a cylindrical sleeve externally fitted to the rotor shaft and extending in an axial direction X; and a plurality of permanent magnets serving as field magnets, the plurality of permanent magnets being provided between the rotor shaft and the sleeve in a radial direction and retained by the sleeve around the rotor shaft. The sleeve is formed by a plurality of short sleeves arranged in the axial direction X, and end portions of the short sleeves that are adjacent to each other, the end portions being butted together in the axial direction X, are mechanically joined together in a torque-transmittable manner.

Abstract: A power system of a ship includes a first power storage device, a second power storage device, and a control system. The first power storage device has an energy density higher than that of the second power storage device. The second power storage device has a power density higher than that of the first power storage device. The control system is configured to: as a power generator application, prioritize discharging the first power storage device over discharging the second power storage device, such that base power is continuously supplied to an onboard electrical load connected to an onboard bus; and as a grid stabilization application, prioritize charging/discharging the second power storage device over charging/discharging the first power storage device to compensate for frequency variation or voltage variation of an onboard power grid.

Abstract: A marine reduction gear makes it possible to reduce the installation space of an electrical rotating machine. A marine reduction gear includes: an input shaft coupled to an output shaft of an engine; an output shaft coupled to a propeller shaft that rotates a screw propeller; a gearbox accommodating an input gear provided on the input shaft and an output gear provided on the output shaft, the gearbox supporting a first bearing that supports the output shaft in a rotatable manner; and an electrical rotating machine including: a central shaft that rotates together with the output shaft; a rotor fixed to the central shaft; and a stator surrounding the rotor. The gearbox supports the stator and a second bearing that supports the central shaft of the electrical rotating machine in a rotatable manner.

Abstract: In a power storage system, a bidirectional DC-DC converter is set into mode for charging a secondary battery with electricity when a first state of charge (SOC) of the secondary battery is larger than a minimum value of the first SOC, and a second SOC of the capacitor is smaller than a maximum value of the second SOC, and the converter is set into mode for discharging electricity from the secondary battery when the first SOC is smaller than a maximum value of the first SOC, and the second SOC is larger than a minimum value of the second SOC. Based on an internal resistance of the secondary battery, the second SOC, a voltage of a direct current link in case of no load connected to DC link, and an error in a current on a direct current link side, a conduction ratio (D) of the converter is calculated.
