A prototype of the flux-modulated type magnetic gear is manufactured and tested to evaluate its efficiency and torque transmission characteristics. According to the test results, the maximum torque transmission is proportional to the gear's size and the flux density of each rotor. The efficiency of the gear is dependent upon core material and core shape. As for the gear made for trial purposes, the efficiency of 99% was obtained in the maximum. The prototype gear obtained comparative advantages over mechanical gears with respect to efficiency and noise.
