摘要

This paper presents a new type of two-stage magnetic gear based on the nutation gearing principle. According to the structure of two-stage nutation magnetic gear, the spatial coordinate relationship between different gears is constructed. The analytical mathematical model of the magnetic torque of the two pairs of magnetic gear and the whole magnetic gear system was obtained. A test model was also built to verify the theoretical calculations.
