A kind of Optimum design method and device for bi-axial magnetic gears which has the following steps: a. provide a non-axial magnetic gear device which comprise two magnetic gears filled with hard magnetic material b. fix the interval between two magnetic gears and the ratio of out ring radius of the two magnetic gears to the thickness of hard magnetic material c. the torque-magnetized coefficient curve of the hard magnetic material has extremum d. according to the characteristic of the magnetic gear device, magnetize the two magnetic gears with an optimum magnetized value e. separately change the interval between the two magnetic gears and the ratio of out ring radius to the thickness of hard magnetic material; and repeat steps c and d.
