This article deals with the magnetic gears with modulating ring and mechanical epicyclic gears and their operation. A power transmission analysis is done and permits to obtain an analogy of the kinematics between the two gear systems. Moreover, a transposition of the mechanical epicyclic gear arrangements to a magnetic gear arrangements can be made. Finally, a load repartition evolution description is proposed to complete the comparison between magnetic gears with modulating ring and mechanical epicyclic gears.
