Summary:Although the researches into increasing the transmission torque and the torque density of magnetic gears are performed, setting the torque to the required value after assembling is almost not done. In this study, we examined adjusting the step-out torque by inserting a plane rectangular coil between opposed magnetic gears. It is possible that the magnetic field generated from a coil decreases the step-out torque. Therefore, the relationship between the characteristic value of the coil and the transmission torque was investigated experimentally. The theoretical value of the transmission torque decrease rate by calculation and the experimental result are compared. When the rotational frequency was less than 700 rpm, the transmission torque reduction rate by the coil was about the same as the calculated value, and adjusting the step-out torque by the coil is expected.
