Summary:The magnetic harmonic gear has been studied because of its high magnet use efficiency. However the magnetic harmonic gear are difficult to assemble. So, a new type of the magnetic harmonic gear was proposed. This magnetic gear has the stackable structure and is assembled easily. It was confirmed by simulation that the radial magnetic flux was strengthened by alternately arranging the axially magnets with the same poles and the maximum transfer torque and the magnet utilization efficiency improved. Therefore, we make a prototype of the stackable harmonic type magnetic gear using Halbach array and measure and examine torque characteristics.
