| Abstract |
In the EV sector, geared motors with a single gear ratio are commonly utilized. This study aims to replace conventional geared motors with magnetic geared machines(MGM) by integrating magnetic gears. When designing an MGM, simply applying the conventional design methodology of magnetic gears is insufficient, as the influence of the shared rotor, which serves as the coupling component between the magnetic gear and the motor, must be considered. Therefore, this paper proposes a new design methodology for magnetic gears that accounts for the influence of the shared rotor in an MGM. Furthermore, the study presents the design process for an MGM specifically intended for EV applications. |
