Abstract: A new type magnetic harmonic gear is proposed. The new magnetic gear has the stackable structure and is assembled easily. The proposed magnetic gear has stacked ring magnets and thin iron plates for the inner and outer rotors. And the two types of the inner and the outer rotors are compared. The proposed magnetic gears can transmit the maximum transmitted torque over 1 Nm and the input rotational speed exceeding 2000 rpm. Furthermore, the influence of a stack on the maximum transmit torque is revealed through the experiment. Also the maximum transmitted torque is checked through the simulations.

Keywords: Magnetic gear, stackable structure, magnetic flux concentration, maximum transmission torque
