This paper proposes a new electric magnetic-geared (EMG) machine, which artfully incorporates the magnetic gear into an outer-rotor inserted permanent-magnet (PM) machine, purposely for electric unmanned aerial vehicle (e-UAV) application. The proposed EMG machine artfully shares the sandwiched-rotor for both the PM machine and the magnetic gear. As a result, the proposed machine can run in the high speed and high power for propelling the e-UAV. The design details, operation principles, static characteristics, and machine performances, as well as the propulsion performances of the proposed machine, are elaborated and discussed. The finite-element method is utilized to verify the validity of the machine design and performances, with emphasis on the e-UAV application.
