Abstract

A magnetic-geared motor in which an electric motor and a magnetic gear are magnetically combined is expected to be put into practical use. In a previous paper, a magnetic-geared motor was prototyped, and the feasibility and usefulness were demonstrated. However, the efficiency of the prototype geared-motor is not enough high. This paper describes the efficiency improvement of the magnetic-geared motor by both increasing torque and reducing losses. The improved geared-motor demonstrates that the efficiency is improved remarkably. Furthermore, feasibility for applying to walking support machines is studied.
