Abstract
In this paper, we investigate the characteristics of a novel magnetic-geared induction motor, in which the rotors synchronize with the rotating magnetic field produced by the coils. The operational principle that the high-speed rotor is driven as an induction motor and the low-speed rotor is rotated as a magnetic gear is described and the characteristics are computed using 3-D finite element method. In addition, the computed characteristics are verified by carrying out measurements on a prototype. The rotation speed was not decreased although loads were increased. This inherent behavior was verified by the measurements.
