Title: Ryo Miyamae: Patents in Electrical Machinery and Marine Gear Systems

Introduction

Ryo Miyamae is an inventor based in Kobe, Japan, whose patent work addresses electrical rotating machines and marine propulsion systems. He is associated with Kawasaki Jukogyo Kabushiki Kaisha and has 2 patents listed in the provided information.

Latest Patents

Miyamae’s listed patents focus on practical design improvements for rotating machinery and marine gear systems.

“Rotor of Electrical Rotating Machine” describes a rotor with permanent magnets held between a rotor shaft and an outer sleeve. The sleeve consists of multiple short sleeves arranged along the shaft’s axis, with adjacent ends mechanically joined to transmit torque. This construction provides a way to retain the magnets while connecting the sleeve sections to transfer rotational force.

“Marine Reduction Gear” combines a reduction gearbox with an electrical rotating machine. The gearbox accommodates the engine-connected input shaft and propeller-connected output shaft, and supports both the output shaft and the electrical machine’s stator. A central shaft rotates with the output shaft and carries the machine’s rotor. The arrangement is intended to reduce the installation space required for the electrical rotating machine.

Career Highlights

Miyamae’s listed inventions connect electrical machine design with marine drivetrain engineering. His work includes both rotor construction and the integration of an electrical rotating machine into a marine reduction gear.
