A magnetic gear transmits torque without contact. The torque just before the gear idling defines the maximum transmission torque of the magnetic gear. The maximum transmission torque of the magnetic gear is defined by the strength of magnet and the gap between gears at the stage of design. In this paper, we focus on the adjusting method of the maximum transmission torque at the time of use. The adjusting method is to change the facing length of the magnet gears by shifting the one of gears in the axial direction. Thus, we reveal the relationship between the torque and the facing length and the relationship between the torque and the gear gap. The limit torque can be assigned on basis of the obtained relationship.
