Outline of Final Research Achievements

In this study, we conducted a feasibility study of a magnetic-geared motor and generator by both numerical analysis and experiment.
First, we compared an axial-gap-type magnetic-geared motor to a radial-gap one. As a result, the radial-gap one is superior to the axial-gap one even if the machine structure becomes flat, because the radial-gap type can be utilize a dead-space inside the gear part, thus the space utility factor was improved in comparison with the axial-gap one.
Next, prototype tests of the radial-gap-type magnetic-geared motor were conducted. As a result, torque of the prototype machine exceeded a required characteristic.
